The Hum is a generic name for a series of phenomena involving a persistent and invasive low-frequency humming noise not audible to all people. Hums have been reported in various geographical locations. In some cases a source has been located. A well-known case was reported in Taos, New Mexico, and thus the Hum is sometimes called the Taos Hum. Hums have been reported all over the world, especially in Europe. A Hum on the Big Island of Hawaii, typically related to volcanic action, is heard in locations dozens of miles apart. The local Hawaiians also say the Hum is most often heard by men. The Hum is most often described as sounding somewhat like a distant idling diesel engine. Typically the Hum is difficult to detect with microphones, and its source and nature are hard to localize.

Funny how they never look into RF pollution creating all these cross over frequencies and subsequent audio harmonics. Can't have them brain cooking cellphone towers off the market though and people that hear hums can buy earplugs.

Is there anyway you could switch of the electricity and see if you can still hear it? And I live in a flat and my neighbor upstairs has in the past had computers and tv's that have kept me awake, not through the noise but the vibrations they cause. Could it be something like that?
