The
Scientific Paper on Hum Geography follows this preamble.
(We fear less what we understand)
The HUM is an unusual noise, heard usually, but not exclusively,
nocturnally. It is reckoned only to be
heard by between 2 and 11% of the World’s population in industrialised regions
and is characterised by tones matched by hearers in the region 30-80 Hz yet not
necessarily detectable by acoustic detectors or instruments at these
frequencies. Superimposed upon the higher frequencies perceived are present
pseudo random modulations in the region 0.25-5 Hz giving an effect sounding
like a very large bee trapped in a bottle but often considerably lower pitched
and barley discernable yet can be extremely
annoying or distressing to some of those afflicted.
The HUM was first heard in the UK in the late 1960’s and early
1970’s and first heard in the USA in 1976 but more extensively the early
1990’s. More recently, it is heard in Scandinavia, Germany, Australia and New
Zealand and now even parts of Italy, Russia, China, South Africa and South
America. It seems that as the World
becomes more industrialised there are more cases of the HUM. This fact alone suggests the HUM must,
somehow, be associated with infrastructure.
Only a handful of past publications have sought to understand
the HUM and there are several World Wide Internet Forums on the subject which
sometimes sadly get abused by idiots and crackpots banding about UFO and
conspiracy theories. Such ideas frustrate the real Science of the HUM. The present author’s internet publications
are attempting to redress the balance.
These are of
course exactly the times when pumped storage is generating!!!

Abstract – First hand experience of this enigmatic, infrasonic phenomenon is
described. The effects of location and weather conditions on the perceived HUM
characteristic and level are investigated. It is shown that the HUM is a very
real physical phenomenon. Further that at least for certain electro-sensitive
individuals, two additional essential ingredients for their perception or
augmentation of the HUM appear to be both the presence of UHF/ microwave
electromagnetic radiation and low frequency magnetic fields, the latter
either arising from 50 Hz mains or power grid or, alternatively, powerful local
medium wave a.m. radio transmissions, which of course vary considerably with terrain
and geographic location. This requisite
for both field types is confirmed using both anthropogenic and
laboratory field sources. Furthermore
there is a fairly critical dependence on the strength of both fields concerned
which goes a considerable way to explaining the previously reported almost
hap-hazard nature of the HUM. Possible mechanisms for this kind of interaction,
at microwave intensities often much lower than those involved in the Frey
effect and at a cellular biological level are discussed. One of the individuals
concerned can also perceive a 50 Hz magnetic field as a continuous low
frequency buzz in the absence of significant levels of higher frequency
radiation. A dependence of the HUM level
on coupling at the air-body interface and on the presence of passing vehicles
and wind speed confirms the involvement of at least one UHF or microwave
electromagnetic or acoustic component. The author’s son, an individual living
in the same household as the author and his wife rarely hears the HUM but
reports fewer sleep disturbances on nights when weather conditions reduce the
HUM amplitude. An additional explanation
of why the HUM is mainly perceived at night and not in cities is presented. Various cases of the HUM around the World are
re-investigated and can be qualitatively explained by the arguments advanced
herein. The HUM is a nocturnal nuisance
and nightmare for some individuals, the human rights implications of sleep
disturbance are discussed. There may
also be implications for the health and well being of even those individuals
who do not physically perceive the HUM per se.
Introduction
The LFN ( low frequency noise/infrasound phenomenon) known by some as the HUM under its various guises; ‘Taos’, ‘Kokomo’, ‘Largs’ and ‘Bristol’, to name but a few, seems to ‘heard’ or perhaps it is more accurate to say ‘perceived’ ubiquitously throughout the Western World by between at worst and best estimates some 2% and 11% of the population. Those who perceive this phenomenon, mainly, although not exclusively at night, are known as ‘hummers’. Both the present author and his wife are hummers. Their son who lives in the same household, although younger than the main hearing group, also occasionally hears the HUM and suffers sleep disturbances at the times when the author perceives the HUM. Thereby this work presents both first-hand subjective evidence of the HUM allied with particularly relevant scientific viewpoint and new hypotheses.
An excellent review of the history, occurrence and some alleged causes of the HUM phenomenon has been given recently by (Deming 2004). While the present author in agreement with Deming, comes to the conclusion that the HUM is electromagnetic in nature he doubts however Deming’s exotic conclusion concerning TACAMO transmissions as the general cause of the HUM, instead preferring the notion that they may only be a small part of the HUM ‘jigsaw’ puzzle.
Interestingly, Deming has stated that relatively speaking the hum has is perceived more extensively in Britain than anywhere else. The present author believes this is to do with the small physical size of Britain relative to the positions of its Electricity distributions system and possibly additionally to its locations of its major UHF Television transmitters which are often co-sited with or very close to powerful medium or long wave a.m. broadcast transmitters.
More recently it has been proposed by Dawes that simply ELF emissions from the UK Power Grid itself, http://homepages.tesco.net/~John.Dawes2/cause.htm, rather than house wiring per se, is the prime and only cause of the HUM phenomenon in Britain. Dawes sees the power grid’s interactions with the local ionosphere as a prime mover for the HUM. There is certainly a huge energy density in the power grid connected to the longest ‘Beveridge’ antenna in the land. It is reasonable to assume some power then will couple to the ionosphere and in fact this has recently been observed, see Mannone (2006). The argument advanced being that most HUM cases in the UK seem to follow the distribution of the 400KV 50Hz electricity distribution grid and that the HUM is still perceived when household electricity master switches are turned off. However, set against this, Britain is so small there are few areas devoid of proximity with the power grid, therefore a lot more people ought to be hearing the HUM if Dawes’ hypothesis is to be believed and if the Hum is purely and singly down to just the power grid.
Others have advanced the notion
the coastal locations are required for any manifestation of the HUM. Indeed,
two of the main UK high profile HUM locations, namely; Largs in Ayrshire, Scotland and Bristol in South
West England meet this criterion. However, these two locations are also
significantly close the super grid power
grid, and equally close to High Power
UHF Television transmitters and additionally close to medium and long wave a.m.
broadcast facilities of 10-100 KW. There
are also locations in

HUM was first perceived extensively at night in

similar proportion of locations in the

Deming (2004) has suggested TACAMO transmissions as the most likely cause of the HUM since these are a powerful source of VLF radio. However such transmissions would not be expected in all locations at all times and would perhaps be more prevalent for coastal manifestations of the HUM.
A re-examination of the data from
the most significant world –wide locations shows some of them are not
necessarily on coasts and that they all have two things in common. They are located
close to both high power UHF TV installations
and high power medium wave a.m. broadcasting facilities often either closely
sited or even co-sited with the former.
Sometimes a microwave mobile phone signal gives stronger field strength
than a TV transmitter, see
The possible exception has been microwave hearing by personnel exposed to radar signals at field strengths of far greater amplitudes than those present in the background environment. In any event regular or routine exposure of the general public to such amplitudes would not be permitted by internationally agreed exposure limits (http://www.emfs.info/issue_ExposureLimits.asp) and so can be ruled out as the general cause of the HUM.
The remaining then is that the
HUM may potentially either arise or be augmented as a combination of the influence of human
exposure to simultaneous high and low frequency electromagnetic fields with in
most cases adequate sources being those fields arising from UHF television and
installations and medium wave broadcast transmitters. This hypothesis potentially explains the rise
of HUM cases in Britain during the 1970’s. In some locations the dominant field
strength in the UHF/microwave regime will be that from mobile phone towers rather
than TV towers and it would seem that there is some evidence to support the
hypothesis that emissions from the former in conjunction with strong medium
wave fields can also augment the HUM.
All three of these types of signal sources are now ubiquitous in society. A certain criticism then of this hypothesis would be that there are fewer HUM reports from big cities than from suburbs and more rural areas. Valid reasons for this discrepancy will be explained later.
The locations
A series of fixed locations in
The fixed locations are as follows
The locations are now described in more detail with respect to geography, underlying geology and electromagnetic environment. Location 1 is the author’s present home town and locations 2-5 were visited while travelling in connection with another employment.
Location 1;
Location 2; Gringley on the Hill
Gringley
is a rural village location on Jurassic limestone and clay sedimentary strata
and is located some 15 km east of
Location 3;Lifton,
Lifton is a tiny low- lying, rural village located on Sedimentary strata and a few kilometres to the North of intrusive igneous strata. It has no nearby high voltage cables or sub-stations and a weak cell phone and very weak TV signal. Lifton is 30 km distant from the nearest TV transmitter and 50km distant from the nearest substantial a.m. radio transmitter.
Location 4;
Location 5; Elford,
Elford is a small low lying village on mixed sedimentary strata and next to a wide river. Elford has overhead low voltage electricity cables with no sign of a local sub-station and no nearby cellular towers. Interestingly some of the properties in the village feature in the British book of ghosts! High voltage grid wires are located about 10 km away. Elford is 25 Km distant from co-sited UHF TV and FM radio and 70 Km away from a major AM radio transmitter at Droitwich.
Local Mobile and outdoor locations
A variety of more local mobile and outdoor locations have been chosen although these are limited to a 10km radius of Bangor and its immediate surroundings. Choice was for proximity to the sea, the high voltage 400KV grid, and TV masts or cell phone towers – all potential and previously ascribed sources of the Hum. It has also been possible to study the effects of the weather upon perception of the HUM at these locations.
Subjective experiences at the various locations
Reports are included of both the experiences of the author and his wife, both hummers, at Location 1 and the various mobile and open air locations.
Reports are only available as the subjective experience of the author alone at locations 2-5.
Location 1
The author’s wife first noticed the Hum in the master bedroom at location 1 almost immediately since moving in some three years ago. She perceives the Hum as the classic ‘fly or wasp trapped in a bottle intermittent buzzing noise’. Repeated attempts to clear the HUM by relocating the bed failed, as expected. Now so sensitised to the HUM, she hears it almost every night and often in other nearby locations even in cars or the open air, particularly near the sea. Both the author and his wife hear the HUM at all locations throughout their house at location 1, however it is loudest nearest windows.
The author began hearing the HUM in location 1 about twelve months ago, prior to that, the only electro- sensitivity or similar he had ever displayed was nausea and vertigo with CRT type computer monitors (thank God for TFT technology) and hearing (inner -head perception) the odd squeak or whistle when constructing and testing extremely high power VHF and UHF amateur radio equipment.
The author’s perception of the HUM is more varied than that of his wife. Firstly the perceived level varies from quiet to sleep disturbing, secondly the perceived modulation on top of an approximate 30Hz background, varies from ‘animal voice’ or ‘lullaby’ to annoying steep rise time ‘Morse –code like’ emanations culmination in either ear popping crescendos or the feeling of the whole head ringing. Sometimes there is ‘modulation’ superimposed on high pitched tinnitus.
Throughout 2005 and in the first
six months of 2006 the author identified a pattern in the Hum which only
appeared to present close to periods of full moon. Of course tides vary with
the moon and to some extent coastal winds. Initially the HUM sounded to the
author more like the classic throbbing diesel engine but over the last month or
so from October 2006, this pulsating modulated HUM however, seems to have
become more aggressive and almost omnipresent nocturnally and can sometimes
even be heard in the daytime subject to interruption by traffic. It is known
that recent changes have happened in the local UHF/microwave environment at
location 1 which may account for these changes in the HUM. Firstly BBC Digital Radio now transmits
from Llanddona. Secondly the North
Both the author and his wife only appear to be sensitive to the HUM on the right side of the head or at least it is perceived in the right ear. A recent study seeking to find the best position for wearing a body mounted 2.45 GHz antenna ( See et al 2007) has shown the right ear and shoulder to be the pair of body points with the lowest radio frequency impedance i:e most penetrable to radio frequency radiation .
The author’s wife has not tried shielding the HUM and seems to be able to consciously blank it out on some nights. The author however, is unable to do this, and has resorted to various methods of screening. It is found that a small square of conductive plastic from a PC component bag pressed firmly between the pillow the facial cheek and outer ear is quite effective. On some occasions, if a hand or non conductive plastic is employed for shielding, a changed or increased pulse repetition frequency (PRF) in the Hum is noted, where subjectively the PRF seems to increase from about 2 Hz to about 10 Hz.
As stated location 1 is extremely noisy in both the very low and very high frequency electromagnetic environments. There is a strong 3D standing wave field at either 900 MHz or 1800 MHz cell phone frequencies as borne out by measurements employing standard satellite finder equipment independently powered up by 9 volt battery.
Low frequency measurements have been taken using ‘Spectrum Lab’ software and a PC Sound card attached to various antenna systems including VHF whip, a ground loop and a torroidal transformer winding. Sometimes when the HUM is prevalent there appears to be swept frequency signals in the range 1-400 Hz and an imbalance in the harmonic content of the 50 Hz mains frequency. This will not be reported on further herein but is worthy of further investigation.
The HUM phenomenon was not significantly influenced by the outage of the Wylfa Nuclear Power Station between May 7th and July 7th or thereabouts 2006-personal communication station Health and Safety manager. The significance of this is that during the outage there would have been more incoming load on the power grid. Dawes (2006) has stated the phenomenon to be dependent on the power grid load.
The 50 Hz magnetic flux density
at location 1 fluctuates from 0.1-0.2 micro-Tesla across each room and was 0.6
micro-Tesla adjacent to the house wiring harness and was 9.0 micro-Tesla
adjacent to the house electricity meter. The RMS microwave electric field in
the master bedroom at location 1 varies between 0.1 and .3 volts per meter in
the bulk of the room but in the range 0.4 to 3 volts per metre in contact with
the windows. The RMS electric field
measures at 882 KHz (Radio
Location 2
The author only had occasion to stay in Gringley one night in early October 2006. The author’s wife meanwhile was reporting the usual phenomenon present at location1.
No HUM was perceived by the author in Gringley on retiring to bed. A very weak effect was however perceived on waking at 0400-0600 but significantly different from that at location 1. The effect perceived was simply that of a very distant and gentle buzzing noise with slow and continuous undulations in amplitude with a periodicity of approximately 0.2-.5Hz. The effect was in no way unpleasant, like that at location 1 and hence the author was able to return to sleep.
Location 3
The effects at Lifton were pretty much identical to the effects at Gringley. Meanwhile the author’s wife perceived the usual HUM at location 1.
Location 4.
Location 5
The house at Elford was allegedly haunted. Certainly the drainage system made some very peculiar gurgling! The guest bedroom the author was in felt somewhat colder than he was accustomed to and he did wake at least half a dozen times in the night. A slight buzzing noise started during the night at about 0400 hours and it was pretty much the same as at locations 2 and 3 maybe slightly louder.
It was not possible to make flux/field measurements at locations 2-5 or to investigate the effects of the weather thereupon since the author’s visits to those locations were only transitory overnight stays.
The mobile and outdoor locations
There have been reports of the
HUM being heard in vehicles but very few outdoor reports. To date the author
assumed this must have been due to masking by the hearing of noise in the
classical sense. Four mobile/outdoor locations were chosen (OL1-4).
Location OL1
This was about 2km South of Bangor and chosen to be as close as practically possible to a privately located GSM ‘Macro cell’ and other communications towers all some 350 metres distant. This tower also carries other trunked radio, PMR and TETRA over a wide range of frequencies from 150 MHz to 2.2 GHz and a couple of 10GHz links at maximum powers of 32dBw per carrier. The 50 Hz magnetic flux density in the vehicle was 0.1 micro-Tesla.
Location OL2
This was about 5km SE of Bangor
and chosen to be immediately underneath a 400KV super grid pylon but with good
line of site to a plethora of cellular and TV towers and to the Radio
Location OL3
This was also chosen to be underneath a 400KV super grid pylon about 4km North of Bangor on the island of Anglesey in a low lying location quite well screened from cellular tower and TV radiation. The magnetic field densities were as location 2.
Location OL4
This was chosen for its proximity
with the sea. It was a quiet coastal location about 5km NE of Bangor and known
as the
Observations at the ‘OL’ Locations
Several visits to each location
were made. The only location where the HUM phenomenon could be perceived
regularly inside the vehicle and irrespective of external conditions was
location OL4. On some occasions the
HUM phenomenon was so intense that it could even be perceived outdoors against
the background noise of the wind and waves!
Due to sea path propagation the medium wave radio
The location where the HUM phenomenon could sometimes be perceived the loudest was location OL2. Perception at this location appeared to depend on the wind speed and was minimal at high wind speed. Another very unusual phenomenon was noted at this location. Use of a standard GSM handset at the author’s right ear at this location provoked an intense and painful sound pulsation in the left ear of the author, one not usually sensitive in any way whatsoever to the HUM phenomenon. It is obvious that the vehicle would not have made an overly efficient screen to the 50Hz magnetic component from the power lines and indeed some 35% of the measured flux density entered the vehicle. It would have been expected, however, that a vehicle forms a pretty effective Faraday cage to the 50Hz electric component.
A strong phenomenon of sorts could be perceived at location OL1 but it did not appear to have the same pulse repetition characteristics as at location 1. It could only be perceived inside the vehicle. This may be because the site is elevated and nearly always very windy. The unusual characteristic could have been because the location is completely surrounded by communications towers of several different frequencies ranging from 400 MHz to 2100 MHz.
No HUM phenomenon whatsoever could be perceived inside the vehicle at location OL3. However an interesting observation was made outside the vehicle on an extremely wet and windy night. The author found that if he stood immediately centrally underneath and in-between the conductors and firmly plugged his ears, a faint inner-head continuous buzzing at either 50 or 100 Hz could be perceived rather akin to the nocturnal buzzing at fixed locations 2,3, and 5. This tends to lend a certain amount of support to the Dawes (2006) hypothesis and the idea that at least some humans are sensitive to 50 Hz ELF through some diction means other than by their external ears. However, the auditory effect evoked by sensitivity to this stimulus is not viewed by the author as being the same phenomenon as the ‘diesel engine’ or ‘wasp in bottle’ like HUM as more commonly perceived and described World-wide.
The HUM, vehicles and the weather
The author has conducted
painstaking studies of many variables which are said to effect perception of
the HUM World Wide. At least at location 1 the largest single dependency of the
amplitude and occurrence of the HUM is on wind speed. This is perfectly
consistent with a UHF/ microwave sources being paramount for producing the
effect. The effects of moving foliage on microwave propagation paths are well
documented (Crosby 2006) and (Zhang 2006) and there can be significant
attenuation and path loss. Thus on windy nights, in particular when the wind
speed exceeds about 20 knots the HUM is not perceived at location 1. Fortunately, although urban, location 1 is
nevertheless surrounded on most sides by foliage and tall trees between it and
the nearest communications towers. Passing vehicles also momentarily attenuate
the HUM at location 1. This is suggestive that the offending signal source is
being scattered into the premises at location 1 from somewhere at or close to
ground level. There are metallic fences and other metallic building structures
opposite location 1 which could be responsible. The notion of street level
microwave fields is more consistent with GSM rather than TV as the major
uhf/microwave source at location 1. It is known that GSM antennas are purposely
designed to radiate along a strongly downwards pointing projection angle (Health.http://www.hants.gov.uk/regulatory/advice/mobilebase.html).
There have also been anecdotal reports from elsewhere that rain attenuates the HUM or that the HUM is much louder in periods of fine settled weather. These are also perfectly consistent with effects on UHF/microwave field strength.
The HUM has almost exclusively being described as a night-time curse. In addition to the fact that it is much quieter at night so people have more chance to discern the phenomenon, there are generally less vehicles moving at night so that UHF and microwave fields present will be more spatially coherent and generally a lot less scattered. When a passing vehicle extinguishes the HUM at location 1 there appears to be a ‘dead time’ of some 2-5 seconds before it is perceived to start again. This dead time is perceived similarly by both the author and his wife. Large proteins and bio molecules have relaxation times which range from picoseconds to seconds (Kostov 1999); the longer times particularly for protein folding, possibly suggestive of direct biological interaction in the HUM perception process, see later. Further it has been stated that biological systems communicate and function coherently (Budagovsky 1999) and (Johnjoe McFadden Quantum Evolution, Chapter 11) therefore coherence time may be a likely factor involved in the detection of electromagnetic radiation by such systems. Moving vehicles and the wind certainly have two things in common; both will certainly disrupt the spatial coherence amplitude of a complex web of standing background UHF or microwave field(s).
Why there are few or no HUM reports from big cities
Because the
So why are
Further possible evidence for electromagnetic involvement
The author can stop the HUM by using a small square of electro-conductive plastic pressed firmly against the sensitive side of his head and face. Even ordinary plastic reduces the HUM level and changes the perceived sound to an increased PRF. The dielectric loss of these materials at UHF and microwave is significant particularly as there will be parallel lumped coupling with the skin. Thus this is further evidence that a radio frequency signal contributes to the HUM. The right ear is one of the easiest points of access of radio frequencies into the body (See et al 2007) and both the author and his wife perceive the HUM in that bodily region.
Initial conclusions to be reached from all the observations
The observations of the present
author are not unlike those of the ‘EmsciTek’
consulting company who were asked to
investigate various locations in
Further, it would appear for that
at least for two specific individuals, namely the author and his wife to
perceive the HUM more or less as previously described elsewhere there always
needs to present at least two significant
electromagnetic components and at significantly different ends of the
radio frequency spectrum. In
There remains the possibility that in addition to medium wave fields, 50 Hz fields at appropriate levels might also, in some way, be involved in the perception of the HUM, thinking particularly significant event involving the GSM handset at location OL2. However, one should perhaps remember that power lines can also act as very good long wire antennas for higher frequencies and lower than 50 Hz as well.
What seems to be emerging is a notion that the HUM is a LFN phenomenon that is somehow also potentiated or augmented by certain types of electromagnetic fields.
An EM field of course has components and it may be possible further to investigate their influence.
Microwave power and ELF field strength dependence; electric or
magnetic?
Since a car acts as a good Faraday screen to electric fields at D.C. and low frequencies it is safe to assume that the low frequency interactions experienced at location OL2 are probably magnetic in origin. On the other hand both electric and magnetic components of a UHF /microwave signal can easily enter a vehicle through its windows,
Having established that frequencies from two very different ends of the radio spectrum seem to need to be simultaneously present for the HUM’S perception, the question arises what if any is the significance of 50 Hz. Can 50 Hz magnetic fields augment the microwave induced HUM as an alternative to medium wave fields?
In order to further explore microwave power dependence and elucidate if 50 Hz low frequency field strength is involved, other experiments were performed. This was particularly important, for it seemed that at the outset odd to the author that he might be proposing a mechanism wherein the interaction of very tiny fields could be perceived and results in the HUM, but yet say the higher fields associated with normal use of a GSM handset didn’t! Perhaps this notion however, is not that strange. The Science of field matching is applied elsewhere, in MRI tomography, for example.
Two experiments were tried. In each experiment the GSM Handset emitted RMS microwave field strength of 112 volts per meter. In the first experiment a GSM handset was activated in a silent call to the author’s landline telephone and left at the end of a room some 6 metres long at a date and time when the HUM was not apparently present. The author moved quietly round the room. At no position in the room could any auditory sensation be perceived. In other words a single carrier 900MHZ microwave electric field strength ranging between 2.85 and 112 v/m in the presence of ambient background medium wave and 50 Hz fields did not provoke an effect. It is interesting to note that at its lowest value this represents electric field strength only some fifteen times the value of the microwave electric field strength which is present when the HUM is being perceived on quiet motionless nights. Thus there is a possible notion of critical relative field levels and perhaps even frequencies to perceive/augment the HUM in the first instance. Further in an ordinary room space, the predominant 50Hz fields would be expected to be electric fields arising from house wiring and perhaps Dawes (2006) ‘wall voltage’
In a second experiment, the GSM Handset was similarly activated and placed adjacent to the right ear of the author which was also placed proximal to a magnetic flux density of 68 micro-Tesla from a fluorescent tube choke. In an instant, buzzing and fluttering noises could be perceived inside the head of the author, which ceased when the handset was de-keyed. This is confirmation that at least in evoking some sort of auditory response, at 50 Hz the magnetic field component is most important. In contrast, since the HUM could be perceived in a vehicle at location OL4 where the 50 Hz magnetic field was minimal there is also the suggestion that a magnetic field at medium wave a.m frequencies is also important in the perception of the HUM. For both frequencies the subject are in the near field.
These experiments suggest that a critical regime of field and flux strength for both the high and low frequency activating components and possibly also of frequency for the latter component are all required to come together to produce a discernible physical auditory effect. It would seem that at least for a 50 Hz magnetic field instead of or in addition to a background medium wave field that the numeric values of flux level expressed in micro-Tesla have to be comparable with the values of Field strength in Volts per meter, i.e. The two fields somehow seem to need comparable amplitudes to biologically ‘modulate’ each other. A well understood analogue of this is for example in electronics wherein amplitude modulation in radio transmission systems when to achieve 100% modulation the audio and radio frequency amplitudes necessitate being equal. It is to be expected that such critical coincidences in amplitudes of two or more field types will only at rather specific geographic locations, which also appears to be a feature of the Hum. Similar cases of types of flux quanta or fields interacting at critical and quantised levels are of course commonplace elsewhere and are commonly exploited in medicine for example in the guise of magnetic resonance and electron spin resonance.
D.C. Magnetic Field dependence
Biological systems have evolved in the earth’s natural and slowly fluctuating magnetic field. In order to ascertain if static DC fields are relevant to HUM perception a small loudspeaker magnet was placed on the head of the author in a variety of positions whilst he perceived the HUM. There was a barely perceptible increase in HUM amplitude with the magnet in situ and anterior to and above the author’s right ear. Such a magnet is expected to have a value of flux density some times greater than the earth’s natural field and locally, ought to swamp out that field. The conclusion is perhaps then that static DC fields are not particularly relevant to the perception of the HUM. The earth’s natural field is of course subject to natural pulsations and this experiment alone is neither sufficient to include or dismiss their relevance in HUM perception. It should also be remembered that the magnet could also have been acting as an antenna enhancing the omni-present anthropogenic microwave field. Neither can the contribution of stellar microwave fields arriving from outside the earth’s geo-sphere be totally ruled out.
Theories of Electrophonic Hearing of the HUM
Vibrations and electromagnetic signals can come from underground rocks. This is predominantly expected of igneous rock which contains quartz and other piezoelectric materials. The HUM is heard in locations which do not lie on igneous rock, the type most likely to be piezoelectric, and sufficient evidence has been presented here and elsewhere to dismiss Earth Piezoelectricity as a major cause of the HUM. That is not to say the geo-electric effects (Beamsish 2006) will not contribute in some way to the local 50Hz field at any location or to the ground wave strength of medium or long wave radio waves both of which are proposed here to be potentially important in the perception of the HUM. Seismic-electric and seismic magnetic effects may be important in the HUM and will be discussed elsewhere.
Dawes (2006) has suggested that ‘electro- gravity’ signals from the power grid are the sole cause of the HUM in the UK. One can certainly see how the 50 Hz could modulate the ionosphere which might under some circumstances result in an AGW ( atmospheric gravity wave) giving rise to acoustic pressure waves or an EA (electro-acoustic) disturbance of the atmosphere. Since a similar pattern is not observed with the power grids in other countries direct hearing of 50 or 60 Hz by whatever mechanism can probably be ruled out as the cause of the traditional ‘diesel engine throb’ associated with the HUM world-wide but could conceivably have a part to play in explaining the effects which the author experienced in locations 2, 3 and 5. Some have argued that HAARP or other ELF military communications systems may have a part to play in the HUM. It is also feasible to see how these too could give rise to AGW type, EA or even ELS (electro-scalar) atmospheric waves. However, it should be remembered that the first reports of the HUM predate installations such as HAARP and SURA.
All the locations World-wide in
which the HUM is perceived appear to be proximal with powerful medium wave a.m.
broadcasting transmitters. Coincidentally, powerful VHF FM transmitters are
almost always co-sited with these. To date there are no well documented HUM
reports from regions more than 20 or 30 Km distance from such transmitters.
Deming (2004) has made reference to people who hear the aurora or large
fireballs entering the earth’s atmosphere, both of which are potentially
capable of producing radio frequency electromagnetic energy in the kilohertz
regions, not so far away from the a.m broadcasting
band. One possible conclusion is then that ‘hearing’ or some kind of
bio-detection of medium wave frequencies alone is sufficient to explain the
HUM. Set against this is the fact that
there is only one reported location where the HUM is discerned which does not
also have a very proximal high power television transmitter, this is Victoria
B.C.in
The observations at the authors’ residence, location 1 are not consistent with the HUM arising simply as a result of a medium wave signal. A medium wave signal would not be disrupted by wind and rain or by moving vehicles.
On balance then hearing of a medium wave signal alone can be discounted as the sole stimulus of electrophonic hearing of the HUM. As stated earlier that does not mean to say that a medium wave or low frequency component is not an important or even crucial addition to a UHF or microwave component in HUM perception/or augmentation.
Microwaves are known to generate sound in polymeric and dielectric materials given appropriate power levels and pulse widths or time –gating. It is thought this generation is due to thermo-elastic and electrostrictive mechanisms (Guo 1988, Hosten 1998 and Bacon 2001). There is no reason to suppose that these mechanisms might not also prevail in biological molecules particularly biopolymers with similar structures. Frey (1962) has proposed a thermo-elastic mechanism for hearing microwaves. According to Frey it has been shown that microwaves of appropriate power level and pulse modulation period can be heard by a considerable sub-set of the population.
Estimates of the peak power from a GSM Handset are about 8 times the RMS output. Power levels from the mobile Handset are just about within reach of provoking an auditory response according to the Frey (1962) effect dependent on pulse width. However, in this present study, a response with the handset could only be provoked in the presence of a considerable 50 Hz magnetic field. Doubtless during Frey’s original experiments there would have be some background low frequency fields present. These are more or less ubiquitous in social housing as well as in scientific premises. Sadly, the values of such low frequency fields are not documented in the work of Frey thus a further evaluation is not possible.
The microwave electric field strengths in the bedroom at location 1 are some two to three orders of magnitude below those documented in the Frey effect but it is still a hundred times greater than those recommended for sleeping areas by the Burgerforum
BRD proposal 1999, see http://www.powerwatch.org/news20050207_tonight.asp
It is unlikely then that the Frey effect of thermo-acoustic stimulation is the likely biological detection mechanism for the HUM. However erring on a note of caution, it should be remembered that Frey (1962) did not consider the effect of animal or human bombardment by multiple radio frequency carriers in the UHF and microwave spectrum characteristic of the real life situation in many homes today, both afflicted and otherwise by the HUM. It is possible that beats between various carriers may give rise to bio-acoustic effects hitherto not yet adequately investigated. However, even if there were to be a sub-set of the population who can perceive microwaves well below the threshold levels defined by Frey (1962) as a result of beats between several microwave sources, this still does not account for the observable facts, i.e. the need for there to be present a significant and additional low frequency a.c. field.
There is some evidence to suggest that such deposits as calcites exist in the pineal gland (Baconnier 2002 and Lang 2002). Similar compounds exist in the sacule (part of the inner ear concerned with gravity, acceleration and balance). However, the observable facts simply do not support these as the seat of the HUM detection and perception. If detection were by means of a sort of ferroelectric detector one would expect a direct dependence on field strength with perhaps just one resonance frequency depending on the size and location of the deposit. One would also expect less dependence on location and many more HUM hearers. This is quite simply not observed. However, under some circumstances HUM like effects are observed at certain key distances form transmitters, this may involve ferroelectric deposits and quantum mechanical magnetic vector potential effects which will be discussed later and elsewhere.
Notions of coherence and quantum
effects in Biology were first pointed out by Herbert Fröhlich FRS (1949). Fröhlich truly was a Physicist ahead of his time, as has
been pointed out by Smith (2006) very recently. Smith (2006) cites more than
twenty Fröhlich references including Fröhlich, H. (1980).
Larmor resonance of cellular structures and ion cyclotron resonance are simply two such examples of coherence involving magnetism and electromagnetic fields.
These models ( Ledner 1990), Volpe 2003), (Matronchik
2005), (Nair 2006) and (Pafur 2006) have been used to
explain the non –thermal behaviour of isolated collections of living cells
exposed to electromagnetic fields. It would seem they also hold out the most
reasonable promise to explain the manifestation of the HUM as a non-thermal
biological effect. Both models predict
quantisation in the range of allowable field, frequency and flux values which
will bring about biological effect either rotation of cellular organelles in
the former model or rate modulated ion efflux and biological activity in the
latter. Both models are in support of
the observable results for the HUM at the various locations studied and of GSM
handset experiment. The notion that
quantization be required with respect to levels of allowable field(s) to bring
about an effect fully supports the observed hap-hazard nature of the HUM at
locations World Wide, in that not all locations could possibly be expected to
support the required field or flux Eigen values. Only when locations with a ‘perfect match’ to
the required resonance conditions are found will the HUM be perceived. Even at a fixed location or building wherein
residents sometimes perceive the HUM, there is no reason to suppose ideal
conditions for its perception at times will be met. For instance UHF and microwave and cell
phone signal paths tend to fade with changes in ambient weather conditions etc.
(BBC NEWS (2006)
The ion cyclotron resonance model explains how mainly low frequency electric or magnetic fields might modulate a biological process in the presence of a fixed DC field such as that of the Earth. Ion cyclotron resonance frequencies for common biological ions are in the region 1-200 Hz. Thus invoking the phenomenon of ion cyclotron resonance alone would be sufficient to explain the author’s personal sensitivity to the 50 Hz power grid. On the other hand, if ion cyclotron resonance alone was responsible for the perception of the HUM one would have perhaps expected a much more pronounced effect from the loudspeaker experiment.
Larmor resonance of larger cellular organelles is predicted to occur causing slow rotation at microwave frequencies (Matronchik 2005) and under the influence of constant or slow time varying magnetic fields (which could presumably be applied at 50 Hz or even at kilohertz or medium wave frequencies) this would be an alternative mechanism for the coupling and detection of low energy microwaves in say the inner ear. The mass and charge of cellular organelles vary as a result of interactions with proteins and ions. It is feasible to see therefore how under certain conditions processes set up by Larmor resonance in biological systems may be modulated by ion cyclotron effects and vice versa. Movement of whole cellular organelles in the cochlear or its nearby region as a result of these unique resonance processes will be sufficient to set up piezoelectric stimulation of the cochlea’s hairs and hence produce an evoked auditory response, with or without the aid of ion cyclotron resonance. The slow rotation associated with Larmor resonance would also be expected to give rise to quite long temporal coherence times and would elegantly explain the dead time experienced in HUM perception after say the passage of a nearby vehicle.
Further with coherent ‘bio-detection’ of the HUM non-linearity and long coherence times would mean perceived responses might bear little if any semblance to the original modulating frequency or pulse repetition frequency. The noise presently perceived by the author has some slight semblance of GSM TDMA or CDMA modulation but cannot be accurately discerned as either. GSM and TETRA signals do vary in amplitude, but are not amplitude modulated per se. Nevertheless, it would seem, some hearers of the HUM certainly seem to perceive more complex noises the more background ‘electrosmog’ is present. It is possible the original idling diesel engine effect comes about from a combination of just one dominant UHF or microwave carrier and one dominant ELF or MF field. Either the perceived fluctuations are internally generated, being due to blood flow or external and due to slowly fluctuating variations in the UHF or microwave path which are well documented. Similarly there are slow fluctuations in the underlying earth’s D.C. magnetic field, but in view of the ‘loudspeaker result’ these may be less relevant or even discounted. Little wonder then that some ‘hummers’ have been almost driven mad trying to come to terms with their ‘inner’ sounds. Little wonder even many physicians and general practioners have ascribed the HUM to low frequency tinnitus or even schizophrenia! Sadly we now know for sure this is definitely not the case. The proponents of sub-cellular and quantum theories of electromagnetic interaction will take relief that their hypotheses now at last appear to be vindicated and validated not only in the test tube but also by whole body evidence at the ‘person’ level.
As of 2005, a scientific hypothesis suggests
the HUM originates on the eardrums of affected individuals as a result of the tensor
tympani muscle trembling. In other words they suggest that the HUM
is nothing other than a form of tinuitus. (The tensor tympani is a muscle
within the inner ear for tightening the eardrum.)
The 40-page hypothesis can be read in German on the pages of the German
Association for Research about the Hum, IGZAB (InteressenGemeinschaft Zur
Aufklärung des Brummtonphänomens). See: http://www.IGZAB.de . See de:Brummton Phänomen.
It is difficult to see if the HUM is simply due to tinutus why removing the affected indivuduals from a particular location also removes the HUM. Tensor Tympani Syndrome has been reported previously (see Klochoff 1979). Klochoff (1979) explains how the Tensor Tympani Muscle only produces a reflex which responds to very strong and startling noises in humans. However, very interestingly, reflexes could also be initiated in the muscle as components of startle response initiated elswhere in the body! For instance such initiation could by via an orbital air jet. Raised tension in the tympanic membrane as a result of spasm of this muscle can render the ear upto ten times more sensitive to air pressure changes than normal. The representative impedance pattern of the ear however, showed slow variations with pulsatile spikes superimposed. Certainly the present author is often conscious of something vibrating inside his ear when he perceives the HUM, but at a much faster pulse repetition frequency. The outer ear canal can act as a Helmoltz resonator and thus blocking or partly blocking the outer ear flap would be expected to change the pulse repetition frequency if it were actively radiating sound. This is exactly what happens for the author. The low random buzzing pulse repletion frequency of the HUM gives way to a higher regular pulse repletion frequency of approximately 10Hz as the ear is gently covered with a hand or piece of plastic and the signal cuts off altogether when conducting plastic is used instead. The rate of trembling of this muscle or whatever other structures are excited, clearly and significantly exceeds the rate during that which is described as the ‘Tonic Tensor Phenomena’ (Klochoff 1979). It seems inconceivable that such a rare biological phenomenon would affect two separate individuals in the same household simultaneously, as is the case when the author and his wife perceive the HUM. Unless that is the syndrome is being triggered by outside influence. Klochoff (1979) states that 80% of individuals afflicted by Tensor Tympani Syndrome also suffer from dizziness and vertigo. Neither the author nor his wife suffers from these.
The proposition thus, which is open to contention, is whether or not the tensor tympani muscle or other parts of the ear tremble of their own accord in certain individuals for whatever physiological reasons, or are induced to tremble by external means. Directly coupled low frequency and voltage stimulations cause nerve impulses to be created and can cause muscle twitching. This mechanism is exploited in electrical muscle toning devices. Remotely coupled electric and magnetic fields are known to cause bio-effects at high levels. The question is here then how do they produce significant bio -effects at levels which have hitherto by many considered as being safe.
6. Combinations of the above, the body as a
coherent detector
A possible mechanism for the HUM could be some kind of combination of mechanisms 4 and 5 above. An experiment was devised to see if the HUM could be created purely electromagnetically under laboratory conditions. The author did not have access to UHF and microwave signal generating equipment but did have a GSM handset and also used a VHF frequency source of 144.74 MHZ. A swept lower frequency source was available spanning 1.6 – 40 MHZ.
With the GSM handset in a silent call to the author’s landline telephone and a lower un-modulated frequency of 1.6 or 8 MHZ and field strength of 110 V/m, a weak effect could be perceived. Rather than the usual pulsation of the HUM the author was only able to create a weak buzzing sensation in the inner ear, but given that the signal sources were at higher field strengths than the external signals thought to produce the HUM and single and un-modulated frequencies, this biological effect in his own body is regarded as significant . Further the mechanism above would suggest and confirm that two distinct high and low frequency groups were necessary.
Some HUM hearers and electro-sensitive individuals say that they experience biological effect other than the HUM per se. For example Huttenen has observed involuntary hand movements in a moving VHF electromagnetic field. http://herkules.oulu.fi/isbn9789514297601/isbn9789514297601.pdf
While exploring the combined effects of a range of high and low frequency groups the following was found. At frequencies of 5.16 and 144.74 MHZ both fed into indoor omni-directional aerials and with his head in the near-field of the aerials, estimated to be at some 110 volts/meter at both frequencies, a strong twitching of the author’s left eye lid was induced.
The author has thus shown
biological effects as experimental
proof of the existence of ‘two frequency
bio-effects’ and further he believes
than on the weight of evidence provided such effects are also a feasible cause
of either HUM perception and/or
augmentation in the general population
at large. Similar to the 50 Hz
experiments it would appear that the field strengths at the two frequencies
need to be comparable for the effect to be induced.
It has been noticed that transmission bursts from the local 150 MHz paging transmitter modulate background 50Hz field amplitudes at location 1. A human brain however sensitised or entrained to slow changes from a modulation envelope in this way be it by ion cyclotron resonance or pineal deposits may some how then be able to coherently detect that modulation form the higher from envelope by say Larmor resonance or whatever. Thus some combination of the above hypotheses may turn out to be the actual mechanism of HUM perception. It is interesting to note that in the case of the Kokomo HUM the Emscitek study points out that the signals from WIOU were so strong they were modulated onto all the local electricity supplies and house wiring, possibly then they also modulated the local cell phone transmission in some way. The body or brain or certain neurones then act like some sort of a coherent or phase sensitive detector for all the envelopes concerned. Even free and bound bodily water may be involved.
Smith (Dallas,2000), has recently linked
biological coherence and acupuncture and has been studying acupuncture and
homeopathy in relation to water memory imprinting which he shows to be a physical
effect based on frequency rather than a chemical effect. The classical and Voll
acupuncture meridians are shown by Smith to have associated high and low
frequency bands, which can be entrained to respond to external stimuli. Several of the important acupuncture
meridians and their main stimulating points are seen to have frequencies which
coincide with radio and microwave frequencies in the environment.
For instance, in relation to HUM perception, it
is possible that the small intestine high frequency band of 1.2 MHz, frequency
as defined by Smith, could be entrained by medium wave broadcast transmissions.
It is astonishing to note, that on standard acupuncture charts, this
The kidney and liver upper frequency bands are
47 KHz and 240 MHz respectively. It is very interesting to not that these are
two other meridians which acupuncturists have used to treat tinnitus. Smith (Dallas 2000) has shown that the kidney
meridian will entrain at 50 KHz. Both these frequencies ought to be present in
the radio frequency environments of many locations. 50 KHz will arise as beats
between multiple TDMA GSM users and 240 MHz is very close to the new DAB radio
broadcasting band. Interestingly Deming
(2004) has stated that kilohertz radio frequencies may also be a feature of the
TACAMO system which he alleges is the main cause of the HUM.
In the specific experiments which produced
movement evoked bio-effects in the body of author, frequencies of 144 .74 and
5.16 MHz produced eye lid spasm. If Smith’s hypothesis is correct then these frequencies could have been coupling
into the body at GV14 and possibly also at the Gall Bladder Meridian. 5.16 MHz
is very close to twice the natural Gall Bladder frequency stated by Smith
(Dallas 2000). Of course quantized Eigen values or harmonic frequency jumps are
to be expected in coherent systems.
Again employing Smith’s ideas, in the experiment with the mobile handset
and the co-applied lower frequencies of either 1.6 or 8 MHz which produced
auditory response it is possible the fourth harmonic of the liver frequency or
Ren Mai was being stimulated by the handset and the lower frequency applied was
stimulating either the small intestine or stomach meridian by entrainment. Now we can see there are several equally
possible mechanisms for the body to detect or coherently absorb electromagnetic
radiation. It is not unreasonable to assume that one or a combination of these
is responsible for bringing about vibration of component(s) of the ear either
directly or indirectly as by initiation of the startle response and hence
attendant perception of the HUM. Because
of the complexity and non-linearity of the processes concerned the original
pulse patterns or modulations in the stimulus signals are unlikely to be
preserved.
Smith
(2002) points out the general dangers of frequencies from the external
environment to biological systems, especially man. He further re-examines cancer epidemiology of distance related
effects from radio and television transmitters. He states that for coherent
detection it is necessary to have the magnetic A and B fields 180 degrees out
of phase. Since the A field (strictly A-potential) travels through the true
vacuum and is not slowed by the refractive index of air as is the B field then
there will always be a frequency and distance dependent phase difference between
the A and the B field from radio transmitters. For a full understanding of
Smith’s hypothesis it is necessary to first understand the quantum mechanical
phenomenon known as the Aharonov-Bohm
effect (http://en.wikipedia.org/wiki/Aharonov-Bohm_effect).
Particualry, since Webb et al. (1985) have demonstrated Aharonov-Bohm
oscillations in ordinary, non-superconducting metallic rings; for a discussion,
see Schwarzschild (1986) and Imry & Webb (1989) and Bachtold et al. (1999) have detected the effect in carbon nanotubes, it
is not unreasonable to suppose that the Aharonov-Bohm effect would not be relavant in biologoical systems
or within their component water and cells.
On this basis Smith
(1989) accounts for why cancer clusters maximize not in the immediate vicinity
of a powerful VHF FM transmitter but some 5 Km distant. The ratio of the speed of electromagnetic
waves in a vacuum compared to that in air is 1.0003 to 1, so that at a frequency
of 100 MHz this represents a half wave length or 180 degrees of phase
difference of 1.5 m (transit time difference 5ns) or maximum biological coherence at some 5 Km
from the transmitter. It is exactly here where the ratio of observed to
expected cancer cases doubles! In fact
close to the transmitter there are no cases of cancer over and above those
expected normally. Further credence for Smith’s ‘acupuncture’ hypothesis (Smith
(Dallas 2000)) is lent when one considers that 98.4 MHz is the centre frequency
for the acupuncture ‘allergy’ meridian according to Smith. Interestingly many VHF FM broadcasting
transmitters in the
An alternative mode of detection for
the HUM is just as possible. Imagine that the electromagnetic stimulation
renders the ear much more sensitive to changes in pressure similarly as in
Tonic Tensor Phenomenon. When it is
really quiet, usually at night the HUM is mainly perceived. It is possible that
the HUM is airborne infrasound only perceived because of this sensitizing
effect of the dual frequency electromagnetic radiation. This does not detract from the need for a
coherent radio frequency component or components or from the fact that the UHF
component of the HUM is disrupted by passing vehicles. Airborne infrasound is
ubiquitous in the environment at frequencies from .01-10 Hz and with coherence
lengths of up to 100metres. It is known
that infrasound can be used as a detector of approaching storm fronts etc... It
is interesting to note that some reports of the HUM correspond with weather
phenomena and Jet streams. This
hypothesis is strongly supported by the notion that the HUM is mainly heard
indoors because outdoor noise and pressure changes at higher frequencies may
overwhelm the infrasound being perceived. To test this, radio and sound sources
could be set up inside an anechoic chamber. Unfortunately, the author has no
access to one at present. On the
other hand, heightened sensitivity to infrasound may not require being a
consequence of the Tensor Tympani itself, vibrating or otherwise. Smith (Dallas 2000) and elsewhere (Smith
1989) has stated that for bio- effects involving water imprinting, the relative
phases of the magnetic potential A and
field vector B are important. The A
component is unaffected by matter whereas the B component is. Thus any pressure
field which locally modulates the air density, will change its refractive index
and hence the magnitude and phase of the B component. Thus pressure changes due
to atmospheric infrasound will modulate the B component. This ‘modulation’
could then be perceived as the HUM. The highest profile places where the HUM has
been perceived in
It is interesting to examine the distances involved. It is reasonable to assume that entry of an electromagnetic signal may be at whole body level, i:e the body acting rather as a half-wave antenna. Taking a typical FM broadcast frequency of 100 MHz, yields a half wavelength of 1.5 metres, about the height of a teenage child. Taking typical cell phone frequencies of 900 MHz and 1800 MHz respectively yields half wavelengths of 16 and 8 cm respectively i.e. significant fractions of the linear dimension of a human head. The longest motor neurons in the human body have axons which are over a metre long, comparable then with the wavelengths of these radio frequencies.
Assuming cells
in the body truly respond in a coherent manner, we can expect some sort of
stimulus to be excited more or less uniformly throughout the body, or
alternatively that coupling is into long axons, for non-linear and quantum
effects classical radio frequency attenuation need not apply.
Nevertheless it is probably safe to assume that if an auditory response
is initiated this will be in the regions of the head or brain normally
responsible for evoking such responses when the ear is stimulated acoustically.
This would line up with the notion of a possible involvement of the small
intestine acupuncture meridian and the fact that the right ear is more
sensitive to the effect. It is known
that the main site of electrical transduction for the acoustics side of
the ear is within the cochlea and that
the dimensions of this structure’s
‘hairs’ range from 3-500 microns with most being in the tens of microns
size bracket and about 3 microns in diameter.
It is not unreasonable to assume, that effectively then, any
‘modulation’ of the B field(s) involved ought at least to produce an amplitude of deflection of a few percent of the size of these
hairs of these hairs, if hearing of the
HUM is focused within the traditional hearing apparatus of the ear! Calculation
shows this to be a tiny phase shift of the original transmitted frequency i.e.
some 0.002 degrees. The author has show
that at location 1 the HUM disappears completely with wind a speed exceeding
some 20 Knots, similarly it momentarily disappears when cars pass by at similar
speeds. Calculation of the Doppler shift on a wavelength of 32 cm (frequency
900 MHz) yields some 0.3 microns at speed of 20 Knots. It would seem that if
the HUM is perceived in this way, there must be a saturating effect above a
certain hair displacement. Assuming the bulk B field component which arrives at
location 1 is scattered randomly by the induced wind movement then this will
also disrupt any spatial and temporal coherence in the incoming signal and
cause loss of the HUM perception. Alternatively and secondly the induced
modulation of the B field by the wind might be in phase with the normal external
auditory response and therefore not perceived by the brain as the same
annoyance or irregularity as with slower or quieter modulations which give rise
to the HUM. Either argument is further
in support of the notion that the HUM will not as readily be perceived in big
cities as in more rural locations, because of higher background noise and
continuous vehicular movement as cited earlier.
The Hum single effect or multiple?
Deming (2004) has pondered over whether the HUM World-wide is a single effect or has multiple causes. He concluded that on balance the HUM is probably a single universal effect.
However, the weight of the evidence presented here is that possibly two separate or multiple cause(s) and effects have been identified.
At least from the author’s personal experience, he would appear to possess some sensitivity to 50Hz fields as borne out by the experiment at location OL3. This experience was far more like the phenomenon experienced at locations 2, 3 and 5 and was not in any way unpleasant. A possible mechanism for ‘hearing’ 50Hz in this way is most likely ion cyclotron resonance. 50Hz also corresponds closely with integer harmonics of the low frequency bands of several of the acupuncture meridians as given by Smith. That is not to say that 50 Hz electric fields could not modulate higher frequency B fields in line with mechanism 7 as outlined above. 50 Hz and other ELF frequencies may also appear directly as infrasound and building vibrations due to several various other geophysical mechanisms which will be discussed at a later date.
The Hum World-wide however, is
often described as an unpleasant, highly irritating and all penetrating noise
much more like a ‘wasp trapped in a bottle’ or an ‘idling diesel engine’. This
is the very sound perceived on still nights by the author and his wife at
location 1 and the other recorded mobile and outdoor locations in the immediate
In the laboratory it has also been possible to bring about other similar but not identical physiological effects besides the HUM by using appropriate combinations VHF and HF/MF electromagnetic fields.
Further work
An experiment was initially proposed by the author during the writing of this paper to prove once and for all that the HUM is not in the mind of the sufferer. It is proposed that a portable EEG machine be used on a collection HUM sufferers during sleep at times when the HUM is present and not and /or at locations with the HUM present and not. The influence of a serious disturbance like the HUM should show up on brain waves. The author believes it may even show up on the brain EEG’S of people who don’t physically perceive the HUM as aural stimulation, given the experiences of his own son. It would seem, on making a thorough and final search through the literature towards the end of the writing of this work that a very similar study (The Austrian Study 2005) has, indeed, recently been made and has been cited by Dr Grahame Blackwell at http://www.starweave.com/masts. Its results show significant perturbations in the EEG trace of individuals placed within 50 metres of a mobile phone base station transmitter without their prior knowledge of its location.
Humans are not the only mammalian species to suffer adverse effects as a result of pulsed electromagnetic radiation. A recent study has shown cows too are very adversely affected; see Loscher and Kas (1998).
HUM Prediction
Based on the ides of Smith (Dallas 2000) it should be possible to predict with some certainly precisely which sites will suffer from the HUM and those which will not. From epidemiological cancer studies (Smith 1989) it would appear that sites wherein for a given radio frequency the magnetic A and B components are exactly 180 degrees apart (i.e. in anti-phase) ought to be associated with the largest bio-effect. If the HUM is a bio-effect then at the largest probability of hearing the HUM ought also to be associated with the same type of phase difference.
The present author proposes that it would be instructive to follow a natural extension of these ideas and consider sites where A and B are in anti-phase as a result of any odd integer multiples of 180 degrees. At these sites too the HUM effect should be maximised. Broadly this appears to be borne out by the experimental results
For example, Location 1 is some 400 meters from a 900 MHz
TDMA GSM Macrocell. This represents a phase
difference of 144 degrees between the A and B magnetic components at that
frequency, sufficient to suggest significant biological effect if adopting the
ideas of Smith (Dallas 2000). The
recently installed Police Tetra Mast on Bangor Mountain some 1.25 Km distant presents a serious problem with the A
and B fields being exactly 180 degrees apart. Consistent with such ideas,
Location 1 has a serious HUM problem which as of late, as predicted by the
theory got worse. On the other hand at
location 4 East Hoathley had no HUM problem.

From Table 2 it can be clearly seen that
locations which have no HUM are, either as originally predicted in this present
work, large distances from UHF TV transmitters and AM radio transmitters,
Location 4 fits this category or alternately they may be located much closer to
such transmitters provided they are not located in such a way as to have the A
and B magnetic components from nearby VHF, UHF or microwave sources arriving in
anti-phase. A significant exception
to this rule, at first sight, appears to be location OL3 which has the relevant
230 MHz DAB signal components arriving in an odd integer multiple (5) of
anti-phase. Location TX1 also has no HUM but the DAB signal components arriving
almost in anti-phase. The conclusion must be therefore that DAB does not
contribute to the HUM. This is perhaps
hardly surprising
in that DAB uses an unusual modulation
technique known as COFDM (coded orthogonal frequency-division multiplex). The
multiplex data stream is spread over about 1500 QPSK-modulated carriers so
that, in spite of interference and drops in field strength, the COFDM
demodulator in the receiver picks up an adequate number of signal components
for evaluation. Perhaps because all the
energy is not packed into one discrete frequency bio-effect is less likely. The
modulating frequencies of the individual carriers are also well above the
threshold of human hearing. However, it should also perhaps not be forgotten
that DAB is transmitted in the 220-240 MHz band, a band of frequencies close to
the natural frequency of the liver meridian according to Smith (Dallas
2000). The liver meridian is actually
one used by acupuncturists for treating tinnitus! An intrinsically very similar modulation
method is used for digital television so any assumptions relating to TV
transmission and the HUM will be perhaps more likely to relate to UHF Analogue
TV. This would also line up with the observation of the HUM mainly appearing in
Certainly the locations that have bad HUM,
namely; location 1 and location OL2 and the worst HUM; namely location OL4 have
the A and B components of the UHF TV signal arriving in anti-phase. This is
complemented by the same components of the TETRA signal arriving in anti-phase
at all three of these locations. At
location 1 there may also be some contribution from VHF FM and particularly 900
MHz GSM as borne out by the effects of cars passing at street level. Both these signals also have A and B
components almost in anti-phase. In
locations OL2 and OL4 however the VHF FM magnetic components are almost in
phase so this might tend to rule out VHF FM transmissions as a major player in
the HUM.
The
locations with moderate HUM were all significantly more distant from a
UHF TV transmitter. Sources of the HUM at AF1 and RL2 would appear then to be
predominantly 1800 MHz GSM whereas at RL1 900MHz GSM would appear to be
responsible. These being the only possible HUM causing transmissions arriving
at the aforesaid locations with their two relevant magnetic components in
anti-phase.
Very close to the main GSM macro cell co-sited
with TETRA, some 350 meters distant, location OL1, a different subjective HUM
experience occurred. The HUM was more like continuous white noise and has much
less of a pulsating characteristic. Clearly there was a bio-effect but not the
same as those at greater distances or with fewer frequencies involved.
Similarly this was the case as close as practically possible to the UHF TV
mast, some 300 meters, location TX2, there were similar effects. It should not be
forgotten however that an appropriately ordered GSM signal was also present at
this location. It should not be
forgotten how enormous the field strengths and power levels would have been at
this location. These results for the HUM
appear to add considerable credence to Smith’s (1989) explanation of cancer
epidemiology around TV masts.
Such investigations will form the basis of important further work for the present author and ought hopefully similarity for others in this exciting and challenging field. With the advent of newer modulation methods and precise future documentation and site assessment the HUM might, hopefully, become a plague of the past.
The overall conclusion based solely on Table 2 is then that for perception of the HUM there has to be a source of UHF or microwave frequency (ies) at 400 MHz or above wherein the magnetic A and B components arrive at the hearer in anti-phase. More often than not the UHF component can be provided by a powerful television transmitter but in some locations 400 MHz TETRA or 900 or 1800 MHz GSM signals also contribute to a greater or lesser amount. Additionally there needs to be proximity of less than 17 Km with a powerful AM radio transmitter (10KW at source). The additional contribution of 100 MHz VHF FM to the process is possible but questionable. The author intends to conduct further studies into HUM prediction in order to fully validate the magnetic A/B hypothesis and to show which type of UHF frequencies and transmission most provoke the HUM. It is hoped to submit the results of such a study as a short follow up paper.
Psychological studies and Medical Statistics.
Another ideal way to assess the effects of the HUM would be to conduct psychological tests on HUMMERS and non- HUMMERS in both real trials and double blind trials. Schools and Universities could check for correlation of exam results with student’s residential location and measured field strength(s) therein for example.
Medical statistics could be checked to see if there are increased reports of ‘tinnitus’ coming from certain areas or locations where the HUM is either known or expected to be prevalent according to the above hypotheses. Physicians and doctors who are not aware of the HUM would to date have been expected to have diagnosed HUM sufferers as victims of low frequency tinnitus, depression or even schizophrenia!
Legal significance.
As more and more evidence gathers to prove that the HUM is a real biological effect it may become necessary for the relevant industries to take this on board. European Human Rights Law states that individual residents of member states have the right to peaceful and undisturbed sleep. Clearly for HUM sufferers that is not always possible.
Some European countries are
taking a sensible and cautious approach and have adopted the BurgerforumBRD proposal 1999, see http://www.powerwatch.org/news20050207_tonight.asp.
The future
Human kind is probably living through the greatest changes in their natural and anthropogenic environment ever encountered. Besides a rise in the HUM we are seeing unprecedented rises in teenage mental illness and mental illness in general including geriatric dementia. Evolution is being hurried at a hitherto unnatural pace.
The author sincerely believes that electromagnetic pollution is a major contributing factor.
It would be almost impossible to turn our backs on the technology we have developed and come implicitly to rely upon unless of course we are eventually forced to do so by catastrophic global disaster. We should perhaps consider using technology to our advantage by providing homes with electromagnetically screened sleeping areas or using systems to reduce the coherence of microwave radiation entering our homes or even by developing electromagnetic and or acoustic masking technologies rather similar to noise cancelling headphones on a jet fighter. Further it would make common sense for the major players in the broadcasting and telecommunications industries to fund such developments if they are not eventually to be driven out of business by law suits filed by millions of injured parties. The author’s personal opinion is that it will shortly be proved that ‘HUMMERS’ are just the tip of an iceberg. Prevention is better than cure; otherwise a potential scandal far greater than dioxin or asbestos might lie just around the corner.
