Auditory Brainstem Responses as Indicators of Hearing Aid Performance

Abstract

A procedure involving the utilization of auditory brainstem responses (ABR) to indicate effective amplification is reported. The procedure involves eliciting ABRs by clicks presented in sound field to the aided ear and the estimation of an aided ABR threshold. The method allows for the selection of the ear responding best to amplification in very young or uncooperative hearing-impaired patients. Case studies including electroacoustical analyses of the amplified click stimuli and aided ABRs are presented.
