7 mystical sounds and signals whose nature no one has revealed

Several times in 1997, the National Oceanic and Atmospheric Administration (NOAA) recorded an unusual sound coming from the depths of the Pacific Ocean. The “roar” rose sharply in volume and was noticeable enough for sensors 5,000 kilometers from the sound’s epicenter to pick it up.

According to one of the working versions, it is quite possible that the sound is emitted by a living creature or even a large group of living creatures – for example, giant squids. Judging by the distance the sound traveled, it could also be from a creature larger than the blue whale. Science does not yet know such an animal.

For many years, residents of the city of Taos in the southwestern United States have been hearing low-frequency noises of unknown origin coming from the desert. The noise of Taos, which is also called the Taos hum (Taos hum), ranks first in the ranking of the most incredible natural phenomena.

It resembles the movement of some heavy machinery, although there is no railway or highway near where it is distributed. The peculiarity of the buzzing is that only locals hear it, but tourists very rarely. Scientists have not been able to find the source of the buzz. They only suggested that the power lines passing near the village could be the cause of its appearance.

It’s also called the sounds of the apocalypse or the creaking of the earth (good names, huh?). This is a sound anomaly that has been recorded in different parts of the Earth. “Moan” has been recorded many times on audio media, and a lot of people hear it.

It first appeared in 2011. Whatever theories put forward about it: the most common version seems vague: “large-scale energy processes”. This can include, for example, powerful solar flares.

Another aquatic nature sound. Similar to cooing or moaning, it was recorded on March 1, 1999. Scientists gave it the sweet name of Julia, although it may turn out that the source of this sound is not sweet at all. The coo was recorded by an autonomous array of hydrophones in the eastern equatorial Pacific Ocean.

On May 19, 1997, the United States National Oceanic and Atmospheric Administration picked up a mysterious sound. It was called “Slowdown” – due to the fact that every seven minutes the frequency of the sound decreases and becomes persistent.

The “slowdown” was recorded by an autonomous underwater acoustic recorder in the equatorial Pacific Ocean. Its range is 2,000 kilometres.

This sound almost went down in history. The sources of the mysterious rumble can be not only the depths of the ocean. It was a radio signal that Dr. Jerry Eyman recorded on August 15, 1977 while working on the Big Ear Telescope.

Struck by the closeness of the characteristics of the received signal to the expected characteristics of the interstellar signal, Eyman circled the corresponding group of symbols on the printout and signed on the side: “Wow!” (“Wow!”) This signature gave the signal its name.

In addition to the rather prosaic theories, there is also That Same – an alien ship. And although Eiman himself was skeptical, he later revised his views, although he urged “not to draw far-reaching conclusions”. But we know…

The source of this sound is well known, and the story of its origin brings tears to your eyes. This is called the 52 hertz whale. This is an unknown species of whale that appears from time to time in different parts of the ocean. It “sings” at a frequency of 52 Hz – a much higher frequency than the blue whale (15-20 Hz) or the fin whale (20 Hz). That is, his relatives … simply do not hear him.
