By some estimates 2 percent of the population can at some time hear a mysterious sound known as “the Hum”. It’s a low pitched, droning noise that seems to have no source, yet comes from all around. The Hum has been heard in tiny Scottish villages, in Florida, Western Canada, New Mexico and other regions around the world. Hearers of The Hum have variously blamed distant diesel engines, remote submarines on maneuvers, underground pipes, industrial generators. The sources have never been definitively identified, and so the Hum sufferers have continued to search in vain for an explanation to the maddening sound.

Various theories — mostly of the conspiracy kind — have been proposed. Some put the sound down to secretive government agencies testing ultra-low frequency mind control. Others believe the sound to come from UFOs or instruments of socialist torture.

A more mundane explanation suggests the mysterious signal to be inside the heads of its listeners — nothing more than a form of irritating tinnitus. But many have remained unconvinced and have sought rational explanations elsewhere. Recently, sufferers and researchers have honed in on a potential source — low frequency oscillations of the Earth caused by long ocean waves on the sea floor.
