Abstract
A short general review of the Hum and progress in its
research is presented. The paper defines Hum type 3 as that associated with
electricity and power. Two chance findings
during a radio show phone in session have enabled the author to make very profound
and important links with the ceasing of certain key power generation nodes in
the UK and spontaneous eruptions of the Hum immediately thereafter in other
areas and hypotheses for this are advanced. The signal properties emitted by power systems
are shown to ideally match the received signal properties of the Hum.
Introduction
The Hum is a generic term for a usually pulsating low
frequency sound which is either difficult and/or impossible to trace and/or
record and is perceived by a relatively small percentage of populous. The Hum has been described by those afflicted
as sounding rather like a large bee trapped in a bottle or a distant irregular
idling engine. The noise is often louder at night and in semi-rural or urban
areas which in themselves are not too distant from industrial areas, larger
cities, power stations or high voltage pylons.
In the UK and the USA high
pressure gas mains also often follow the same or similar corridors to the high
voltage electricity distribution grid as
this makes planning consent easier and limits dual scarring of the
landscape.
The characteristics of the Hum are also closely
associated with those of low frequency noise. The latter though is often
traceable. The present author was initially sceptical about the involvement of
the electricity power grid in the Hum but over recent years and aided by
experiment, personal experience, anecdotal reports and further informed by the results of a
radio Wales phone in program called ‘Good Evening Wales’ he is now absolutely
convinced. The author has given Hums
associated with the power grid a specific title and refers to them as Hum Type
3.
Hum type 3 differs from other types of Hum in that the
source per se seems untraceable other than it maximises in certain houses in
certain geographic locations and under power lines and sometimes at certain key
distances from radio transmitters when in a parked vehicle. Clearly Hum type 3
is prima facia an incredibly complex beast and indeed the author feels that one
reason traditional scientific journals have rarely embraced the Hum is that
they simply don’t understand it. Others
have ridiculed the Hum and those who research it as, once again, it is basic
human nature to ridicule or scoff at things we don’t understand. Even University academics who have
investigated the Hum haven’t got very far. Thus as a totally independent
researcher, the author feels proud that he his possibly one the foremost
authorities on the subject in the World!
For example scientists at Southampton University have got no further
than Hum type 1 i.e. noise from distant factories! This was known about just after the
Industrial revolution and referred to as the Hummadruz! Early descriptions of the Hummadraz
however differ from the pulsating noises heard today. Then we have Dr Geoff Leventhall
of the University of Salford who has been investigating the Hum for forty years
and still doesn’t have the answer!
Hum type 3
So what sets Hum type 3 apart from the others besides
its lack of traceability? The answer is
in its unique properties. Hum type 3
appears to have multiple acoustic and infrasonic components but it also appears
to have magnetic or electro-magnetic components. Hum type 3 components seem to need to arrive
coherently to produce effect. Hum type 3 is influenced by planetary cycles
space physics and the physics and seismicity of the solid earth yet many other
aspects of its behaviour point purely to an anthropogenic source ( refs all the
author’s work to date).
The biggest single anthropogenic energy source on our
planet is our power systems. Power systems create signals which fulfil all the above requirements to
produce type 3 Hum. Power systems have
been shown to interact in space. The energy in Power systems is created by and
often dissipated in synchronous rotating machinery. Thus wherever such machines are mounted there
will be radiated airborne and ground borne vibrations which have intimate phase
relationships with each other and with their attendant elctro
(magnetic) fields. Likewise similar
signals will also be radiated from all the conductors in the interconnecting
network. Overhead conductors can not
only radiate signals into space but also cause ground borne induction into gas
mains, water mains and railway lines as well.
In multi-pole synchronous machines there will be sub harmonic
frequencies for example the 500 rpm motor –generator sets at dinorwig will have the sixth sub harmonic of
the uk mains associated with
them i.e. 8.33 Hz. Today power systems
contain lots of sold state technology such as SVCS and STATCOMS which will
emphasise harmonic generation and so more efficiently couple their energy into
space. Also these days there is more DC injection into power systems from
things as mundane as electronic metering systems to PV inverters and wind
turbines. Such injection gives rise to
transients and inter-harmonic frequencies also radiated as above. Small wonder then that cases of the Hum
appear to be increasing.
Ground borne and airborne vibration and
electromagnetic signals can travel large distances of tens or even hundreds of
kilometres and thus it is not always possible to source the Hum.
The best evidence to date
The best anecdotal evidence to date on these matters
came to the author during a radio Wales
interview. A lady in the Wye Valley
being interviewed on ‘her Hum’, clearly a type 3, stated that it began in April
2012. The author has noticed that coincidentally this Hum commenced upon the
permanent closure of
one of the reactors at Wylfa nuclear power
station. During the programme another
lady phoned from Central Wales to say she had a Hum which began exactly a month
earlier. A little searching revealed this coincided with the permanent closure
Of Oldbury power station reactor number 1. A couple of weeks after the programme,
the author decided to see if other UK Hums could be correlated in a similar
manner. The results are staggering and serve to confirm power systems
involvement and just how complex is such involvement, see table 1.

It can be seen that whenever a substantial provider of
electrical power into the UK grid has ceased, a HUM seems to start up
immediately in some totally distant and unrelated area. There are two possible
hypotheses leading to this. Clearly in order to maintain capacity in the grid more power must be generated elsewhere.
Either by using existing power stations, in which case the Hum may be caused by
overload on sections of grid which have never before carries such high current
or by more stray acoustic and electromagnetic coupling form such sections. As an alternative still related to the
provision of energy more embedded generation may be called into play. For
instance it is well known that a lot of water authorities and health
authorities have their own very large emergency diesel generators and can be
contracted to feed the grid at times of need and emergency. Such generators are
often not well screened against vibration and/or acoustic radiation. For those
plagued with the Hum in the regions tabulated, it might well be worth pursuing
such lines of enquiry.
One thing is for sure. This chance finding is the
strongest possible link yet showing a connection between power systems and type
3 Hum and is similar to the link exposed for wind generation and specific motor
generator pairs at Dinorwig for the Bangor Hum. For
example three phase synchronous machines can execute torsional
oscillations when connected to uneven loads (ref) which would serve only to
accentuate the Hum.
Further work
Now the origin of Type 3 Hum is well and truly ‘out of
the bag’ the author is researching what makes a Hummer? In other words is there a special or
particular type of person that is sensitive to the Hum? A link with pulsed radio systems has
previously been suggested but is there anything else?
