Are they gentle or do they have sharp edges?

Become aware of the sound in your environment…

Are the sounds giving you energy or depleting your energy?

By ISTA Contributor, Jen Wilson

Alfred Tomatis was a French physician and specialist in otolaryngology, who began working with understanding the function of the human ear and the importance of listening for over forty-five years. In this connection we will look at his discoveries of sound, which ‘charge’ the listener. Tomatis found that sounds that contain high frequency harmonics, such as those found in Gregorian chants, are extremely beneficial. It is these high frequencies around 8000 Hz, which are capable of ‘charging’ the central nervous system and the cortex of the brain. In many of the sacred chants of the different tradition, the main output of high frequency harmonics are dominant, which offer stimulation to the brain.

Tomatis himself discovered this when he was called to help a Benedictine monastery, where the monks were suffering of fatigue and depression. He found out, that their usual six to eight hours of chanting – due to a new decree –  had been ceased, and within a short period of time the monks were unable to perform their many duties. When Tomatis re-established their daily chanting, the monks were soon able to continue their rigorous schedule of work and prayers.
For Tomatis, a major aspect of the therapeutic effects of vocal harmonics lies in the conduction of the bones, which are stimulated by resonance of around 2000 Hz. He said:

The sound produced is not in the mouth, not in the body, but, in fact, in the bones. It is all the bones in the body which are singing and it is like a vibrator exciting the walls of the church, which also sing.
Bone conductions actually amplifies the sound through resonance of the cranium and the skull.

According to Tomatis, bone conduction stimulates the stapes muscle of the ear, which he believes is the key to stimulating and charging the brain. Tomatis himself managed with a small amount of sleep, less than four hours a night. He attributes this to his listening to sound, which are rich in high harmonics.
