After nearly three decades, the scientific community has not been able to decipher the mysterious sound of only 2% of the population
The cause of The Hum, a mysterious low-frequency sound that ranges from 30 Hz to 80 Hz, is released regularly and only 2% of the world's population hears in isolated places so far. Mystery for scientists.

According to the report, since the 1950s people have begun to recognize cases of abuse by an unpleasant low-frequency sound like a roaring or rumbling roar, a phenomenon never before appeared.

The cases of hearing this sound all have some things in common such as appearing mainly in suburban or rural areas, echoing in the house and louder at night than during the day.
One of the first places on Earth to report on The Hum is Bristol, England. In the 1970s, about 800 people in this coastal city said they heard a flapping sound. At that time, the researchers said that the cause of this strange phenomenon was traffic and local factories operating 24 hours.
The town of Taos in New Mexico, USA is also another famous place that many people hear The Hum. Beginning in the spring of 1991, many residents in the area reflected the low rumble they heard. Researchers from New Mexico's Los Alamos National Laboratory came to check in but they could not identify the source of the sound.
The Hum's mysterious sound was also discovered in some other places: Windsor, Ontario, USA and Bondi in Sydney, Australia.
According to a 2003 study by audio advisor Geoff Leventhall in Surrey, England, only about 2% of people living in the discovery area of The Hum heard the sound. And most of them are in the age of 55-70.
According to the description of The Hum listeners, this sound is similar to the sound of a diesel engine running close by. That cry really drove people crazy and desperate.
Most of The Hum's victims have normal hearing. After being harassed by The Hum, they often experience symptoms such as headache, dizziness, nausea, nosebleeds and sleep disorders. Even at least one suicide case in the UK is thought to be caused by The Hum.
The Hum researchers believe that this strange and mysterious phenomenon is real, not the result of listeners' paranoia or collective hysteria.
A lot of hypotheses about the source of this mysterious sound such as industrial equipment, central heating in buildings, high pressure air paths, power lines . have been given.
Researchers also speculate that low-frequency electromagnetic radiation, which only some people hear, is the source of The Hum. Because many people have special sensitivity to signals that are outside the normal hearing threshold of humans.
The hypothesis due to the tinnitus given by medical experts was quickly eliminated because many victims were able to hear normally and did not experience tinnitus.
Some researchers argue that seismic activity such as seismic shock, low frequency vibration in the ground due to ocean waves caused The Hum.
Another theory is that The Hum was created due to unconfirmed military and submarine communications.
All of these explanations are 'loophole' and do not have a comprehensive view. So, until now after nearly 3 decades The Hum is still the most mysterious phenomenon for people.
Currently, The Humans' victims must rely on noise-canceling machines and other devices to minimize or eliminate this annoying sound.
