sometimes lethal loud vibration.

What We Know About The Hum
The mysterious Hum phenomenon is around since the 1950s and plagues
people around the world, from Bristol, England to Taos in New Mexico,
USA, Bondi in Sydney, Australia and Windsor in Ontario, Canada.
Only 2-4% of people hear the noise. The low-frequency buzz is mostly heard indoors in rural and suburban locations.
The rumbling sound can get louder during the night, and is very
location specific: The Bristol Hum, The Taos Hum, The Bondi Hum, The
Largs Hum, The Windsor Hum.
What is the Cause of The Humming noise?
The cause for the low-pitched roar is a mystery, although many scientific researchs have been written on the subject.
The most probable theories include:
exposure to industrial equipment;
high pressure gas lines;
wireless communication devices;
electrical power lines;
electromagnetic radiation; and
the mating calls of Midshipman fish
secret military experiments
submarine communication
alien activity.
Medical Origins of the Hum?
That humming noise isn’t tinnitus (Ménière’s disease). No link has
been found between both although medical experts still suggest, it’s a
form of tinnitus.
Another medical theory suggests that the hum is caused by trembling of the tensor tympani muscle in the ear.
Dr David Baguley, head of audiology at Addenbrooke’s Hospital in
Cambridge, estimates that environmental factors such a fridge,
industrial fan or nearby factory may be the source of at least a third
of cases.
His own theory – based on years of research – is that many sufferers’
hearing has become over-sensitive concentrating the mind on certain
frequencies of sound which it perceives as a threat.
What Are the Symptoms of The Hum?
Although it may sound like a minor inconvenience, many people claim
that The Hum has had a massive negative impact on their quality of life.
For some individuals, the phenomenon was so terrible, it drove them to suicide.
Symptoms are Insomnia, pounding head, difficulty concentrating,
dizziness, headache, burning skin, tension, pins and needles, muscle
spasms, heart palpitations, nose bleeds, eye strain, ear pressure,
nausea and fatigue, panic and desperation.
Solutions Against The Hum?
High quality microphones cannot record the sound. Moreover, people in the vicinity of the sufferer aren’t hearing anything.
Ear plugs or hearing protectors do not help and in fact only seem to exaggerate the problem.
This suggests that the source makes the whole body vibrate at a
frequency of around 10 MHz upwards, which is lower than the average
person can hear.
As you may have understood it, there is no rational explanation for
“the Hum”. The theories range from motorway noise to the moans of the
tormented souls in hell.
