Scientists have been left baffled because they can’t figure out what causes a phenomenon called The Hum, or why it affects so few people.

Sufferers have identified common factors: the humming is only heard indoors, it is a low, rumbling noise, it is louder at night, and is more common in more rural areas, reported The Huffington Post.

In the UK, the noise has been heard in Leeds, Bristol, and Largs, Scotland, but has been reported as far as Taos, New Mexico, and Bondi Beach in Sydney.

A 2003 study by acoustical consultant Geoff Leventhall, from Surrey, shows that one in 50 people who live in a Hum-prone place hear the noise, and that most of these people are aged between 55 and 70.
