Reports of “The Hum” have come from all over the world, dating as far as the 1970s. People have claimed to hear an eerie, constant, low-frequency sound that has no visible source. Some don’t hear it; some hear it and are unbothered by it, while others have been said to be brought to the brink of suicide. One example of “The Hum” in Taos, New Mexico, had enough reportings to involve investigations conducted by scientists from numerous universities to locate the source, but no explanation was ever found. One explanation is that the noise comes from movement in the earth’s crust. Some conspiracy theorists blame government tests in mind control, in which a low frequency noise is directed towards a population. Support for this theory came from a disturbing case in 1970, in which Medford, Oregon, became the suicide capital of the United States overnight with a rash of unexplained suicides. It was said that researchers found that an ultra-low frequency wave was being transmitted into the town from a nearby military base. However, this theory and all others have never been proven.
