The
therapeutic potential of sound was first recognized by doctors in the late 19th
century. Sound vibrates in waves at different frequencies and is said to
influence both the emotions and certain physiological functions, such as heart
rate and breathing. Even sounds at frequencies beyond the range of the human
ear can have an impact. Practitioners use various approaches and work with the
voice or with electronic or musical instruments to generate sound waves that,
they claim, restore balance in the body and promote self-healing. Sound
therapies are available throughout the West, and also in Japan.

| HISTORY
Buddhist
monks and Indian yogis have a long tradition of chanting to induce an altered
physical and mental state, and the use of drumbeats to rouse soldiers before a
fight is common to many cultures. Medical interest in sound first arose in
1896, when American doctors found that different types of music could stimulate
blood flow and increase mental clarity.
Machines
using sound waves as a form of therapy were developed in the 1950s and 1960s.
The UK osteopath Dr. Peter Manners evolved cymatics therapy, which is most
commonly used in the US. French ear specialists Drs. Guy Berard and Alfred
Tomatis pioneered auditory integration training (AlT) and the Tomatis method
respectively, both of which are attracting interest in the UK, US, and Europe.
Another technique, physioacoustic methodology (PAM), was developed in Finland
in the early 1990s, and is now gaining ground in Europe. Chanting is common to
many cultures, and techniques
such as Mongolian "overtone" chanting, introduced by practitioner
Jill Purce in the UK, are gaining popularity in the West, particularly in New
Age circles.
Pilot
studies of AlT and the Tomatis method suggest they may help treat behavioral
problems. However, no convincing clinical studies validate claims for the
vibration of body cells or the therapeutic effects of sound on organs and body
tissues.
Various
body tissues absorb and reflect sound waves differently - conventional medicine
makes use of this in prenatal ultrasound scans. However, most doctors are
skeptical about the idea of "tuning in" to cellular vibrations to
treat patients.
CONSULTING
A PRACTITIONER
Sound
travels as waves of pressure, each oscillating at its own frequency, or pitch,
transmitted to the brain via the auditory nerve. In theory, auditory messages
may also affect the autonomic nervous system, which regulates organs and body
functions. Some practitioners claim that, like sound waves, internal organs and
cells vibrate at specific frequencies, and any disruption is symptomatic of
disease. Sound therapy aims to restore disturbed inner rhythms to their natural
state with the use of sound waves. Practitioners use a number of approaches.
Cymatics: A machine transmits
sound waves through the skin to a specific body area. This is said to cause
body cells to vibrate at an optimum, healthy resonance.
AIT and the Tomatis
method: The machines aim to retrain patients who may find it hard to process
certain sound frequencies, such as autistics and dyslexics, to hear and listen
properly. You listen to music that emphasizes particular frequencies, forcing
the brain to hear and process them afresh.
PAM: Computer-generated
sound waves, played through speakers in a special chair in which you sit, are
claimed to lower blood pressure and reduce muscle tension.
Chanting:
You
are taught to use tones in your voice to create a pure sound, said to induce a
meditational state. Treatment usually involves weekly hour-long sessions and
runs for several months. Chanting may be taught at weekend or evening
workshops.
