Summary

The incidence of central auditory dysfunction in war fighters who are exposed to high-explosive blasts while serving in combat have not been clearly determined. The objectives of this study are to determine whether central auditory processing (CAP) disorders are associated with exposure to high-explosive blasts. This study will also examine the incidence, magnitude and timing of spontaneous recovery of CAP function from blast exposure. The information provided by this study will help guide clinicians in both the military and VA health care systems regarding the likelihood of central auditory processing disorders in soldiers returning from deployment and suggest some clinical rehabilitative strategies for the treatment of these patients with CAP deficits.

Interventions

PROCEDURE

Audiological testing

Subjects will take part in a battery of audiological tests meant to evaluate the function and status of the auditory system. These tests are similar to the kinds of testing carried out routinely in audiology clinics, and include behavioral tests of pure tone hearing, speech perception, and central auditory function, and electrophysiological testing of the middle ear and of the central auditory system.
