In 2009, the head of audiology at Addenbrooke’s Hospital in Cambridge, Dr David Baguley, said that he believed people’s problems with hum were based on the physical world about one-third of the time and the other two-thirds stemmed from people focusing too keenly on innocuous background sounds.
The source of "the hum" was located to a fan and a compressor on an industrial site, and yet even after these were turned off some people complained the noise had not stopped. I used to live in the outskirts of Glasgow and heard the hum everyday mainly during the night at the time I couldn’t work out what it was and had never heard about it being a phenomenon till now, about 10 years ago I moved away and never heard it anywhere else since. Some residents have reported hearing a buzzing noise like electricity or a car engine that won't go away. The official response was described by Healy-Rae as “away with the fairies gobbledygook. Some thought it was the fault of gas pipes or power lines, but experts now believe the elusive buzzing is down to “ocean waves”. There may exist individual differences as to the threshold of perception of acoustic or non-acoustic stimuli, or other normal individual variations that could contribute to the perception of the Hum by some people in the population and not by others. "This has been happening all over the world for decades. Age does appear to be a factor, with older people being more likely to hear it. In June 2011, residents of the small rural village of Woodland, England reported experiencing a hum that had already lasted for over two months. A two-hour telephone town hall meeting in 2012 received calls from 13,000 residents, with another 9,000 leaving comments over the next week, although not all of those were from people who could hear the hum.

It is worse when the heads are towards us. I also live in Cornwall and it started here about a week ago. Anyone else affected?
The truth is no-one really knows the cause of "the hum", says Geoff Leventhall, a noise and vibration consultant who has advised the government on the issue. This phenomenon, first noticed in 2009, has also been reported since 2011 throughout Windsor and Essex County in Ontario, Canada. Hi Emma , I live 15 miles from a wind turbine. But the mystery of a bizarre drone that has plagued millions of people around the world could finally be solved, scientists believe. Thank you Researchers say currents in the sea cause the Earth to vibrate subtly, Conspiracy theorists had blamed submarines or even mating fish for the unexplained noises, 'ALIENS' found just 25 miles above Earth could hold the secret to the origin of LIFE, Nasa reveals it will ‘DEFINITELY’ find alien life - in as little as TEN YEARS, Astronomers detect EVIDENCE of 'highly ADVANCED' alien colonies in more than 50 galaxies. [ The Taos Hum was between 40 to 80 hertz. it is horrible and wakes me up in the night, even through ear plugs. One of the researchers reported that the Hum was close to 66 hertz, two octaves below middle C, although it could go as low as the lowest E on a piano.

He managed to trace the buzz to a neighbour's central heating. Read about our approach to external linking. Maybe one of these affects the hum. The Largs Hum in Scotland and Bristol's mystery noise in the 1970s are two of Britain's most famous cases. Women may be more likely to be affected than men. However, these emissions occur with equal frequency across age groups within the population,[citation needed] and the Hum typically occurs in regional clusters and to older people. Human ears generate their own noises, called spontaneous otoacoustic emissions, which affects between 38 percent to 60 percent of people, although the majority are unaware of these sounds. There was a ‘hum’ in Bristol, England, for many years which was found to be a gas turbine at the refinery. The second was an air compressor intake at the Haynes International plant emitting a 10 Hz tone. Even people who cannot hear it can feel the vibrations.

[citation needed]. Also a few months back, I visited a friend in W/Tyrone in Northern Ireland Since the 1980s, the Hum has been bothering people living in coastal towns in the west coastal area of Scotland including Largs, a coastal town about 31 km west of Glasgow. Has this happened elsewhere
