What is Sound Healing? Sound healing is the therapeutic application of sound frequencies to the body/mind of a person with the intention of bringing them into a state of harmony and health. The dictionary defines ‘harmony’ as ‘congruity of parts to their whole or to one another’. ‘Health’ is defined as ‘the state of being bodily and mentally vigorous and free of disease’. The French ear, nose and throat specialist Dr Alfred Tomatis has devoted the last 50 years to understanding the ear and its function. He believes that the ear is the most important of all our sense organs. The ear controls the body’s sense of balance, rhythm and movement and is the conductor of the entire nervous system. Through the medulla, the auditory nerve connects with all the muscles of the body. Hence, muscle tone, equilibrium, flexibility and vision are affected by sound. Through the vagus nerve, the inner ear connects with the larynx, heart, lungs, stomach, liver, bladder, kidneys, small intestine and large intestine. Tomatis believes that high frequency sounds (3,000Hz and above) activate the brain and affect cognitive functions such as thinking, spatial perception and memory. Listening to these sounds increases our attentiveness and concentration.
