Auditory Integration Therapy (AIT) is a specific form of Sensory Integration Therapy focusing on the sense of hearing. Hearing is more than just hearing sounds. There is a processing that must occur as well if we are to discriminate between speech, music, ambient noise, and other sounds.
Many people with autism have very sensitive hearing in that noises can often be so loud as to be painful, causing behavioral issues. AIT programs seek to improve and enhance the ability of people to process the sounds coming in through the ear, to discriminate between verbal sounds, to understand language, and to tolerate the various noises that go on in our world around us (fire alarms, vacuum cleaners, lawn mowers, HVAC systems, change of class bells, etc).
