Abstract

The Audiokinetron is a device that processes music for earphone presentation to patients undergoing auditory integration training, a treatment for individuals with autism and other developmental disabilities. Intensity levels produced by the Audiokinetron were measured under realistic listening conditions with a KEMAR manikin substituted for a patient. Average levels at the eardrum were 110 dB SPL when the device was adjusted to the highest setting employed by a local, trained AIT practitioner and 118 dB SPL at the maximum setting of the device. These levels are potentially harmful to hearing and warrant further safety studies of AIT instruments and protocols.
