[Examination of reaction time--auditory brainstem responses--ABR in noise induced temporary and permanent threshold shift].
This study was conducted to investigate the differences between auditory brainstem responses--ABR recorded in men with temporary or permanent threshold shifts (TTS or PTS). Behaviorally, the tested ears showed insignificant differences in the hearing thresholds at frequencies in the range 0.25-8 kHz. The latency of waves I, III, V and interwave intervals I-III, III-V, I-V were analysed as functions of stimulus intensity. The comparisons between recordings obtained in groups with TTS and PTS showed significant differences in latencies of wave V at 90 dB nHl only. The latencies of waves I, III and interwave intervals were unaltered.
