Estimation of hearing loss in children: comparison of auditory steady-state response, auditory brainstem response, and behavioral test methods.

Abstract

The current pediatric test battery is limited in the severe-to-profound hearing loss range by the inability to obtain frequency-specific thresholds. Auditory steady-state response (ASSR) is an evoked potential test that can accurately measure auditory sensitivity beyond the limits of other test methods. The limited amount of clinical research, however, has delayed the acceptance of ASSR into the standard pediatric test battery. This study compared thresholds from 76 children using ASSR, ABR, and behavioral test methods. Resulting correlations were strong and supported the inclusion of ASSR into the standard pediatric test battery. ASSR testing provides audiometric information that is essential in the management of children with severe-to-profound hearing loss.
