Auditory Integration Training was designed to normalize hearing and the way the brain processes information. Invented by Guy Berard, M.D., French ENT specialist, to rehabilitate disorders of the auditory system, it utilizes an electronic amplifier with variable frequency and amplitude modulation capabilities. What is produced is very gentle holistic music that is listened to over headphones twice a day for ten days. Each session is 30-minutes. A summary of various case histories with samples of hearing screenings before and after AIT can be found in Dr. Berard’s book, Hearing Equals Behavior, published by Keats.
