The Hum

The Hum phenomenon (English Hum The Taos Hum or ) refers to the reported from many areas of the world, repeated perception of a Brummtons by individuals at first cause is not apparent.

History

About the occurrence of such Brummtons was reported in the town of Taos in New Mexico for the first time in 1989. In a survey of 1440 residents of Taos gave to about 2%, to hear the sound. The phenomenon has been studied there in May 1993 with considerable scientific effort, but without success.

In Germany, in the period between 2000 and 2002 occasional mention in the media, which has led, among other things, to increased contact of the person concerned. The German community of interest to investigate the Brummtons has been contacted by 1,500 concerned.

According to a criminal complaint against unknown persons of 200 affected due to injury it came from 2 May 2001 the Ministry of Environment Baden- Württemberg with a measurement with specialized equipment at 13 locations in the absence of a common cause could be found.

Description of the hum

The hum is often concentrated during the night hours and is compared with the sound of a distant truck diesel engine idling. For those affected, the hum can be a strong restriction on their quality of life. Some of these could hum only for a short time perceive in their lives.

Sufferers describe the sound as a low-frequency hum to the vicinity of the infrasound. Some of the sound is sustained, some hear him rising and falling or as a Morse code. Many of the sound in a room is louder than outdoors. At night and early in the morning, the sound at about two-thirds of those affected is strongest. In some cases, could also be observed that the corresponding ripple According changed over time.

Please do not include hum, for a unique source in the space around the listener is known. These fan noise, low-frequency components of traffic noise, but also the hum of transformers can include.

There is disagreement among the parties concerned to distinguish them from a lesser-known form of the objective tinnitus ( Tieftontinnitus ).

Possible explanations

An unambiguous explanation has not yet been given. However, it is likely that it is not always acts in the different perceptions of those affected to the same phenomenon, as clearly distinguish the described properties of the perceived Brummtons often. There are apparently different causes.

There are many explanations, including ones that leave the context of a scientific description. It should be noted that neither the source nor the Brummtons its transmission nor the individual prerequisites for hearing are fully clarified. Many of the conjecture is argued that an external source must meet with an individual disposition.

Many sufferers also explain, to return the Brummtoneffekt to the presence of high-frequency, low-frequency pulses but emitted in electromagnetic fields that can be generated, for example, digital cellular, DECT phones or wireless networks.
