Hearing therapy of A. Tomatis
About 40 years ago, the French otolaryngologist Alfred Tomatis made some amazing discoveries that spurred the development of the Tomatis method. This method has various names: “auditory training”, “auditory arousal”…

Sounds that are not

We listen to a cassette of spiritual music – Tibetan monks or Gregorian singing. If you listen carefully, you can hear how the voices merge, forming one pulsating tone.

This is one of the most interesting effects inherent in some musical instruments and the chorus of people singing in approximately the same key – the formation of beats. When voices or instruments converge in unison, the beats slow down, and when they diverge, they accelerate.

Perhaps this effect would remain in the sphere of interest only of musicians, if not for the researcher Robert Monroe. He realized that despite the widespread fame in the scientific world of the effect of beats, no one investigated their effect on a person’s state when listening through stereo headphones. Monroe discovered that when listening to sounds of close frequency on different channels (right and left), a person feels the so-called binaural beats, or binaural beats.

For example, when one ear hears a pure tone with a frequency of 330 vibrations per second, and the other a pure tone with a frequency of 335 vibrations per second, the hemispheres of the human brain begin to work together, and as a result, it hears beats with a frequency of 335-330 = 5 vibrations per second, but this is not a real external sound, but a “phantom”. It is born in the human brain only with a combination of electromagnetic waves coming from two synchronously working hemispheres of the brain.

“I always liked to ask and learn something new. Nevertheless, until I entered high school, I never enjoyed learning and did not have much success in it. There was a time when I was on the verge of an academic breakdown, when even satisfactory assessments were made with difficulty. And this despite the fact that in childhood I was called a smart child, who, in theory, should study perfectly. Adults, as always, considered the cause of my failures to be lack of diligence. I, disappointing them, despaired more and more myself.

As an adult, I continued my studies at college, where I also did not shine. When I failed the exam, I retook it until I got the mark I needed. Having entered high school, I realized that I needed a new strategy, since there was no longer an opportunity to retake exams here. I could no longer work so hard for such mediocre results, so with all the strength of my despair I rushed to look for this new strategy.

Fortunately, I found it – I managed to overcome my “inability” to learn with the help of binaural beats and dimethylaminoethanol (DMAE) – a component found in seafood.

As a result, academic Sisyphus labor turned into exquisite entertainment, which entailed excellent marks and the transformation of me as a person. I felt as if I had been released from life imprisonment. ”

This introduction begins one of his articles by Richard Kennerly, an American scientist who investigated the effect on the human mental performance of listening to special combinations of sound vibrations called binaural beats.

Thus, binaural beats are one of the most effective ways of organizing brain bioelectric vibrations (and related psychophysiological conditions), while simultaneously ensuring high synchronization of both hemispheres. What happens in the brain when a person “hears” these sounds.

In the 50s, the method of electroencephalography (EEG) was developed, which allows recording and studying the bioelectric potentials of the brain. At the same time, it was found that the frequency of bioelectric oscillations of the brain is able to synchronize, under certain conditions, with various rhythmic stimuli, for example, pulses over a weak electric current, light flashes and sound clicks, if the repetition rate of the stimuli is within the natural frequency range of the bioelectric potentials of the brain.

The brain follows the stimuli most easily in the frequency range of 8–25 Hz, but during training this interval can be extended to the entire range of the natural frequencies of the brain.

Currently, it is customary to distinguish four main types of electrical vibrations in the human brain, each of which has its own frequency range and state of consciousness in which it dominates.
