At the limit of hearing possibilities
French otolaryngologist Alfred Tomatis was the first to systematically investigate the influence of high-frequency sounds on the human psyche.
According to his theory, the child, floating in amniotic fluid during the period of fetal development, hears a lot of sounds that are inaccessible to him after birth — the mother’s breath, her heartbeat, voice, noise from the work of internal organs, etc.
This is due to the fact that during the period of fetal development, the child’s ears are filled with a liquid that conducts sound much better than air; in particular, the liquid is much less attenuate high-frequency
To use his discoveries in practice, Tomatis immersed in the bathroom film-protected microphones and speakers, through which the work of the internal organs of the woman was broadcast. Therefore, it was modeled filtering sound through the mother’s placenta.
On the resulting records most of the spectrum of sounds lay above 8000 oscillations per second. When the recordings made in this way were regularly listened to by children with various disorders — dyslexia, autism, hyperactivity, the changes in their behavior and learning were stunning. This high-frequency sound, according to the theory of Tomatis, awakens a sense of the most archaic connection with the mother.
Such sounds seem to touch the most ancient, primordial layers of our memory — the bliss of being in the mother’s womb, the oneness with the mother — and awaken in the listener this forgotten sense of wholeness.
Research and clinical experience of Tomatis led him to the conclusion that the ear is one of the most important organs forming human consciousness. Before him, most people, including scientists who studied the ear, believed that this body has one function — to hear. They did not notice that hearing is just one aspect of a much larger, dynamic process in which every cell of the body is involved.
Tomatis discovered that the ear does not just “hear,” but the vibrations it perceives stimulate the nerves in the inner ear, where these vibrations are converted into electrical impulses that enter the brain in various ways. Some go to the auditory centers, and we perceive them as sounds. Others create an electrical potential in the cerebellum that controls complex movements and a sense of balance. From there, they go to the limbic system, the head of our emotions and the release of various biochemical substances, including hormones that affect our entire body. The electrical potential created by sound is also transmitted to the cerebral cortex, which is in charge of the higher functions of consciousness. Thus the sound “nourishes” the brain, and with it the whole body.
Another discovery of Tomatis was a direct connection between the range of auditory perception of a person, the range of vibrations of his voice and his level of health. — Compare the colorless, weak voice of a sick person and the sonorous joyful voice of a child! Tomatis developed a special sound recording process called “electronic ear”. In this process, the usual sound is alternately cut out of the high-frequency, then low-frequency component. When a person listens to such a recording, the muscles of his ear are trained by alternately tension and relaxation; thus expanding the range of auditory perception,
There are many documented studies showing, in particular, that this method increases creativity, improves memory and improves the ability to concentrate. Also, there is a significant improvement in the so-called fine motor skills. As a result, even professional musicians noted a significant improvement in musical technique and virtuosity of performance. Similar results were demonstrated by masters of various martial arts and professional racers. Currently, there are more than 300 centers around the world that provide treatment and training on the method of Tomatis.
