Taos Hum

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. 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 a mystery to the listener.
The "Hum" is sometimes prefixed with the name of a locality where the problem has been particularly publicized: e.g., the "Bristol Hum" or the "Taos Hum".


The essential element that defines the Hum is what is perceived as a persistent low-frequency sound, often described as being comparable to that of a distant diesel engine idling, or to some similar low-pitched sound for which obvious sources (e.g., household appliances, traffic noise, etc.) have been ruled out.
Other elements seem to be significantly associated with the Hum, being reported by an important proportion of Hum sufferers, but not by all of them. Many people hear the Hum only, or much more, inside buildings as compared with outdoors. Many Hum sufferers can also perceive vibrations that can be felt through the body. Earplugs are reported as not decreasing the Hum. The Hum is often perceived more intensely during the night.
Some people perceive the Hum continuously, but others perceive it only during certain periods. For some people, the perceived Hum can represent a faint sound and a mild annoyance, while for others who perceive the Hum's sound and/or vibrations more intensely it represents a nuisance that can seriously interfere with daily activities. Common consequences include a lack of sleep, as the Hum can keep some sufferers awake or wake them in the middle of the night.
On 15th November 2006 Dr Tom Moir, of the University of Massey in Auckland, New Zealand, made a recording of the Auckland Hum and has published it on the university's website[1][2]. The captured hum's power spectral density peaks at a frequency of 56 Hertz[3].


It is during the 1990s that the Hum phenomenon began to be reported in North America and to be known to the American public, when a study by the University of New Mexico and the complaints from many citizens living near the town of Taos, New Mexico, caught the attention of the media. However, in the 1970s and 1980's, a similar phenomenon had been the object of complaints from citizens, of media reports and of studies, mostly in the United Kingdom but also in other countries such as New Zealand.[4] It is difficult to tell if the Hum reported in those earlier cases and the Hum that began to be increasingly reported in North America in the 1990s should be considered identical or of different natures. During the last decade, the Hum phenomenon has been reported in many other cities and regions in North America and Europe and in some other regions of the world.

I'm thinking about the natural frequeny of a typical quartz crystal underground. We all posess a natural frequency. I highly doubt that 56Hz will do it, even at R.M.S
