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.
本研究旨在调查患有暂时性或永久性阈移（TTS或PTS）的男性的听觉脑干反应（ABR）之间的差异。行为学上，受试耳在0.25-8kHz频率范围内的听力阈值差异不显著。将波I、III、V的潜伏期以及波间期I-III、III-V、I-V作为刺激强度的函数进行分析。TTS组和PTS组记录结果的比较显示，仅在90dB nHl时波V的潜伏期存在显著差异。波I、III的潜伏期以及波间期未发生改变。
