Each sound has a vibration, and depending on what frequency this vibration will be, it will carry different actions on the surrounding world. Everything is subject to vibrations: man, natural phenomena, the Cosmos and the Galaxy. The material of the article examines the influence of various sound frequencies on a person, his health, consciousness and psyche. And also very cognitive processes occurring in nature.

Infrasound (from Lat. Infra - below, under) - elastic waves, similar to sound, but with frequencies below the range of frequencies audible to humans.

Infrasound is contained in the noise of the atmosphere, forest and sea. The source of infrasonic vibrations are lightning discharges (thunder), as well as explosions and gunfire. In the earth's crust, shocks and vibrations of infrasonic frequencies are observed from a wide variety of sources, including from the explosions of landslides and transport pathogens. Infrasound is characterized by low absorption in various media, as a result of which infrasonic waves in air, water and in the earth's crust can propagate over very long distances. This phenomenon finds practical application in determining the location of strong explosions or the position of a firing weapon. The propagation of infrasound over long distances in the sea makes it possible to predict a natural disaster - a tsunami. The sounds of explosions, containing a large number of infrasonic frequencies, are used to study the upper layers of the atmosphere and the properties of the aquatic environment.

Infrasound - vibrations with a frequency below 20 Hz.

The overwhelming majority of modern people do not hear acoustic vibrations with a frequency below 40 Hz. Infrasound can instill in a person such feelings as melancholy, panic, feeling cold, anxiety, trembling in the spine. People exposed to infrasound experience approximately the same sensations as when visiting places where encounters with ghosts took place. Getting into resonance with human biorhythms, infrasound of especially high intensity can cause instant death.

The maximum levels of low-frequency acoustic vibrations from industrial and transport sources reach 100-110 dB. At a level of 110 to 150 dB or more, it can cause unpleasant subjective sensations in people and numerous reactive changes, which include changes in the central nervous, cardiovascular and respiratory systems, and the vestibular analyzer. Acceptable sound pressure levels are 105 dB in octave bands of 2, 4, 8, 16 Hz and 102 dB in octave bands of 31.5 Hz.

Low-frequency sound vibrations can cause the emergence of a rapidly emerging and also rapidly disappearing thick ("like milk") fog over the ocean. Some explain the phenomenon of the Bermuda Triangle precisely by infrasound, which is generated by large waves - people begin to panic, become unbalanced (they can kill each other). "Infrasonic vibrations with a frequency of 8-13 Hz propagate well in water and appear 10-15 hours before the storm."

The influence of sound frequencies on the human body and consciousness

Infrasound can "shift" the tuning frequencies of internal organs. Many cathedrals and churches have organ pipes so long that they emit sound at a frequency of less than 20 Hz.

Resonant frequencies of human internal organs:

Frequency Hz)	Organ
20–30	Head
40–100	Eyes
0.5–13	Vestibular apparatus
4–6 (1–2?)	Heart
2–3	Stomach
2–4	Intestines
4–8	Abdomen
6–8	Kidney
2–5	Arms
6	Spine

Infrasound acts due to resonance: the oscillation frequencies for many processes in the body lie in the infrasonic range:

• contractions of the heart 1-2 Hz;
• delta brain rhythm (sleep state) 0.5-3.5 Hz;
• alpha rhythm of the brain (state of rest) 8-13 Hz;
• beta rhythm of the brain (mental work) 14-35 Hz [6, 138].

When the frequencies of the internal organs and infrasound coincide, the corresponding organs begin to vibrate, which can be accompanied by strong painful sensations.

The bioeffectiveness for humans of frequencies 0, 05 - 0, 06, 0, 1 - 0, 3, 80 and 300 Hz is explained by the resonance of the circulatory system. There are some statistics here. In the experiments of French acoustics and physiologists, 42 young people were exposed to infrasound with a frequency of 7.5 Hz and a level of 130 dB for 50 minutes. All subjects experienced a marked increase in the lower limit of blood pressure. Under the influence of infrasound, changes in the rhythm of heart contractions and respiration, weakening of the functions of vision and hearing, increased fatigue and other disorders were recorded.

And frequencies 0, 02 - 0, 2, 1 - 1, 6, 20 Hz - the resonance of the heart. The lungs and heart, like any volumetric resonating systems, are also prone to intense vibrations when the frequencies of their resonances coincide with the frequency of infrasound. The walls of the lungs have the least resistance to infrasound, which can ultimately damage them.

The sets of biologically active frequencies do not match in different animals. For example, the resonant frequencies of the heart for a person give 20 Hz, for a horse - 10 Hz, and for a rabbit and rats - 45 Hz.

Significant psychotropic effects are most pronounced at a frequency of 7 Hz, which is consonant with the alpha rhythm of the natural vibrations of the brain, and any mental work in this case becomes impossible, since it seems that the head is about to burst into small pieces. Infra-frequencies of about 12 Hz with a force of 85-110 dB induce seasickness and dizziness, and vibrations with a frequency of 15-18 Hz at the same intensity inspire feelings of anxiety, uncertainty and, finally, panic fear.

In the early 1950s, the French researcher Gavreau, who studied the effect of infrasound on the human body, found that when fluctuations of the order of 6 Hz, the volunteers who participated in the experiments had a feeling of fatigue, then anxiety, turning into unaccountable horror. According to Gavreau, at 7 Hz, paralysis of the heart and nervous system is possible.

Professor Gavreau's close acquaintance with infrasound began, one might say, by chance. For some time now it became impossible to work in one of the premises of his laboratory. Not having stayed here for two hours, people felt completely sick: their head was spinning, they were very tired, their thinking abilities were disturbed. More than a day passed before Professor Gavreau and his colleagues figured out where to look for the unknown enemy. Infrasounds and the human condition … What are the relationships, patterns and consequences? As it turned out, high-power infrasonic vibrations were created by the ventilation system of the plant, which was built near the laboratory. The frequency of these waves was about 7 hertz (that is, 7 vibrations per second), and this posed a danger to humans.

Infrasound affects not only the ears, but also the entire body. Internal organs begin to vibrate - stomach, heart, lungs, and so on. In this case, their damage is inevitable. Infrasound, even not very strong, can disrupt the work of our brain, cause fainting and lead to temporary blindness. And powerful sounds over 7 hertz stop the heart or rupture blood vessels.

Biologists who have studied for themselves how high-intensity infrasound affects the psyche, have found that sometimes this gives rise to a feeling of causeless fear. Other frequencies of infrasonic vibrations cause fatigue, sadness, or motion sickness with dizziness and vomiting.

According to Professor Gavreau, the biological effect of infrasound is manifested when the frequency of the wave coincides with the so-called alpha rhythm of the brain. The work of this researcher and his collaborators has already revealed many of the features of infrasounds. I must say that all research with such sounds is far from safe. Professor Gavreau recalls how he had to stop experimenting with one of the generators. The participants in the experiment became so ill that even after several hours, the usual low sound was perceived painfully by them. There was also a case when everyone who was in the laboratory trembled items in their pockets: pens, notebooks, keys. This is how infrasound with a frequency of 16 hertz showed its strength.

With sufficient intensity, sound perception also occurs at frequencies of units of hertz. At present, the region of its radiation extends down to about 0.001 Hz. Thus, the infrasonic frequency range covers about 15 octaves. If the rhythm is a multiple of one and a half beats per second and is accompanied by a powerful pressure of infrasonic frequencies, then it can cause ecstasy in a person. With a rhythm equal to two beats per second, and at the same frequencies, the listener falls into a dance trance, which is similar to a narcotic one.

Studies have shown that the frequency of 19 hertz is resonant for the eyeballs, and it is this frequency that can not only cause visual impairment, but also vision, phantoms.

Many people are familiar with the discomfort after a long ride on a bus, train, sailing on a ship or swinging on a swing. They say: "I was seasick." All these sensations are associated with the action of infrasound on the vestibular apparatus, the natural frequency of which is close to 6 Hz. When a person is exposed to infrasound with frequencies close to 6 Hz, the pictures created by the left and right eyes may differ from each other, the horizon will begin to "break", there will be problems with orientation in space, and inexplicable anxiety and fear will come. The pulsations of light at frequencies of 4–8 Hz also cause similar sensations.

"Some scientists believe that infrasound frequencies may be present in places that are said to be haunted, and it is infrasound that causes the weird experiences commonly associated with ghosts - our research supports these ideas," Wiseman said.

Vic Tandy, a computer scientist at Coventry University, dismissed all the ghost stories as nonsense. That evening, as always, he was working in his laboratory, and suddenly a cold sweat broke out. He clearly felt that someone was looking at him, and this look carries with it something ominous. Then this ominous materialized into something shapeless, ash-gray, darted across the room and came close to the scientist. Hands and feet were guessed in the blurred outlines, and a fog swirled in place of the head, in the center of which there was a dark spot. Like a mouth. A moment later, the vision vanished into thin air. To Vic Tandy's credit, I must say that after experiencing the first fear and shock, he began to act like a scientist - to look for the cause of an incomprehensible phenomenon. The easiest way was to attribute this to hallucinations. But where did they come from - Tandy did not take drugs, did not abuse alcohol. And he drank coffee in moderation. As for the otherworldly forces, the scientist categorically did not believe in them. No, one has to look for the usual physical factors. And Tandy found them, albeit purely by accident. Hobby - fencing helped. Some time after the meeting with the "ghost", the scientist took a sword to the laboratory to put it in order for the upcoming competition. And suddenly the blade, clamped in a vice, began to vibrate more and more, as if an invisible hand touched it. The average man would have thought of an invisible hand. And this prompted the scientist to think about resonant vibrations, similar to those that cause sound waves. So, the dishes in the closet begin to clink when the music is thundering in the room at full power. However, the whole strange thing was that there was silence in the laboratory. However, is it still? Having asked himself this question, Tandy immediately answered it: he measured the sound background with special equipment. And it turned out that there is an unimaginable noise, but the sound waves have a very low frequency that the human ear is not able to pick up. It was infrasound. And after a short search, the source was found: a new fan recently installed in the air conditioner. As soon as it was turned off, the "spirit" disappeared and the blade stopped vibrating. Isn't infrasound related to my night ghost? - such a thought came to the mind of the scientist. Measurements of the frequency of infrasound in the laboratory showed 18, 98 hertz, and this almost exactly corresponds to the one at which the human eyeball begins to resonate. So, apparently, the sound waves caused Vic Tandy's eyeballs to vibrate and caused an optical illusion - he saw a figure that in fact was not there.

Infrasound can act not only on vision, but also on the psyche, and also wiggle the hairs on the skin, creating a feeling of coldness.

British scientists have once again demonstrated that infrasound can have a very strange, and, as a rule, negative effect on the psyche of people. People exposed to infrasound experience approximately the same sensations as when visiting places where encounters with ghosts took place. The National Physical Laboratory in England, Dr. Richard Lord, and the professor of psychology Richard Wiseman of the University of Hertfordshire conducted a rather bizarre experiment on an audience of 750 people. With the help of a seven-meter pipe, they managed to mix ultra-low frequencies to the sound of ordinary acoustic instruments at a classical music concert. After the concert, the audience was asked to describe their experience. The "test subjects" reported that they felt a sudden drop in mood, sadness, some had goosebumps, some had a heavy feeling of fear. Self-hypnosis could only partially explain this. Of the four pieces played at the concert, infrasound was present only in two, while the listeners were not told which ones.

Infrasound in the atmosphere

Infrasound in the atmosphere can be both the result of seismic vibrations and actively influence them. In the nature of the exchange of vibrational energy between the lithosphere and the atmosphere, the processes of preparation of large earthquakes can manifest themselves.

Infrasonic vibrations are "sensitive" to changes in seismic activity within a radius of up to 2000 km.

An important direction in the study of the relationship between the ICA and the processes in the geospheres is the artificial acoustic disturbance of the lower atmosphere, and the subsequent observation of changes in various geophysical fields. Large ground explosions were used to simulate the acoustic disturbance. In this way, studies of the influence of ground-based acoustic disturbances on the ionosphere were carried out. Convincing facts have been obtained that confirm the effect of ground-based explosions on the ionospheric plasma.

A short acoustic effect of high intensity changes the nature of infrasonic vibrations in the atmosphere for a long time. Reaching ionospheric heights, infrasonic oscillations affect ionospheric electric currents and lead to changes in the geomagnetic field.

Analysis of infrasound spectra for the period 1997-2000. showed the presence of frequencies with periods characteristic of solar activity 27 days, 24 hours, 12 hours. The energy of infrasound increases with a drop in solar activity.

5–10 days before large earthquakes, the spectrum of infrasonic oscillations in the atmosphere changes significantly. It is also possible that the influence of solar activity on the biosphere of the Earth is carried out by means of infrasound.
