AIT is carried out using specifically designed and manufactured audio equipment. For those interested in the science, there are fourteen levels of trap/notch filter frequencies, with a nominal filtering depth of 40 db per rejection filter. The method of audio frequency modulation is provided on a random output basis and is not source-dependant.

The equipment modulates or randomises high and low frequency sounds, as well as intensity levels, reducing the ability to predict an incoming auditory signal. The equipment is also capable of filtering specific frequencies which will have been pinpointed by the practitioner during the pre-treatment assessment. Where possible, audiometric screening can determine at what frequencies a person has hyper-acute or hypo-acute hearing. Depending on the audio screening, the device is set to amplify and/or filter certain frequencies of the sound spectrum. Music is then played on a pre-recorded minidisk or CD system and fed through the equipment. The participant listens to music through the highest quality headphones.

The AIT process uses its unpredictable nature to reduce tendencies to block out sounds, lessens the sensitivity to those sounds, and improves perception
of all auditory information.
