Anomalous sound phenomena in nature

For many years, residents of the city of Taos (southwestern United States, New Mexico) have heard low-frequency noise (hum) of unknown origin coming from the desert ^[3] . The so-called "Taos noise" or "Taos hum" ( Taos hum ) ranks first in the ranking of "the most incredible natural phenomena " in the frequency of their mention by the press ^[4] . The buzz is similar to the movement of heavy equipment along the highway, although there are no major roads in the area of ​​the town.

The peculiarity of the phenomenon is that only local residents hear it and extremely rarely - visitors. Scientists who investigated it, failed to find the source of the hum. They only suggested that the cause of its occurrence may be the lines of power lines passing near the village.

The Taos rumble was shown in the Unsolved Mysteries TV show ^[5] , according to LiveScience, it ranked tenth in the ranking of “ten inexplicable phenomena” ^[6] .

In Britain, the most famous example of the so-called " Bristol Drone" was described in newspapers in the late 1970s. One of the newspapers addressed the readers with the headline: "Have you heard the rumble?" Nearly 800 people confirmed that they heard him ^[7] .

“Sounds of the apocalypse”, also “Earth creaking”, “Earth moan”, “Earth rumble”, “Earth noise” - a term denoting a kind of sound anomaly recorded at different points of the Earth ^[8] . Unlike other similar phenomena, it is well recorded by audio equipment and is heard by most people.

The first creak was recorded in the summer of 2011 ^{[ where? ]} . Scientists try to explain this phenomenon in different ways. Some refer to psychological factors , for example, the site "News of Russia" claims that this version is put forward by a psychologist from the University of Chicago Neil Johnson ^[9] . Others on sound hallucinations or not quite right assessment of sound phenomena ^[10] .
Azerbaijani esoteric diviner V. Alekperov told the Day.az news site that according to some professor Martin Stanville, “the sound of the apocalypse” heralds a pole change ^[11] .
According to the chairman of the International Committee on Global Changes of the Geological and Environmental Environment (GEOCHANGE, Munich ), together with the Global Earthquake Prediction Network ( GNFE , London ), Professor Elchin Khalilov , very large-scale energy processes should be the source of such powerful manifestations of acoustic-gravitational waves. These processes can include powerful solar flares and the gigantic energy flows generated by them, rushing to the Earth’s surface and destabilizing the magnetosphere , ionosphere and upper atmosphere ^[12] .

Windsor Rumble

In Canada , in the town of Windsor (Ontario) , regularly (3-4 nights a week, the maximum fell in the summer of 2011), there is a clearly distinguishable hum (about which the witnesses said "you hear, or you feel"). It is suspected that the source of this may be the operation of the HAARP system. The government became interested in the phenomenon and sent experts for the relevant measurements ^[13] .

Auckland Rumble

On November 15, 2006, Dr. Tom Moir of Massey University in Auckland recorded the Auckland Drone and published it on the university’s website ^{[14] [15] [16]} .

Some possible explanations for strange noises were put forward:

In 2009, the head of audiology at Cambridge Hospital, Dr. David Bagley, said that he estimated that in about a third of the cases, a natural source could be found. In other cases, witnesses simply pay too much attention to “harmless” background sounds ^[7] .

Tinnitus

Ringing caused by the nervous system without external sources. This theory is not able to explain why anomalies can be heard only in certain places on Earth. Also, residents of the area where the hum is recorded may have an individual low-frequency recognition threshold or other individual characteristics, thanks to which only they can hear it.

Spontaneous otoacoustic emissions

Human ears create their own noise, called spontaneous otoacoustic emission , which can be discerned by about 30% of people. The emission feels like a quiet ringing or buzzing, it is most clearly distinguished in complete silence, but most people do not notice it.

Ocean Waves

Researchers at Earthscope USArray have discovered a series of infrasound noises from the collision of two ocean waves . In principle, the resulting sound can spread throughout the globe.
