Auditory Brainstem Response in Patients with Sensorineural Hearing Loss

Abstract

The relationship between hearing threshold of pure tone audiogram and the waves and latencies of auditory brainstem responses (ABRs) was investigate in 42 patients with a sensorineural hearing loss. The results were as follows; 1) Appearance rates of waves I, III and V: Appearance rates decreased as hearing threshold increased but wave V appeared approximately 100% until about 70dB of hearing level. 2) The latencies of waves I, III and V: The latencies of waves I and III did not prolong even when hearing threshold increased. Wave V showed a tendency to prolong with increase in hearing threshold more than 70dB at 2 and 4kHz.
