The effects of inner ear pathologies on wave V latency of the auditory evoked brain stem response (BSR) were studied in 12 selected patients with flat, low-frequency, severe high-frequency, and gradual high-frequency sensory hearing loss. In patients with flat and low-frequency sensory hearing loss (Meniere's disease), the latencies of wave V at intensities 4--10 dB greater than their response thresholds were roughly the same as those in normal-hearing subjects. In patients with severe high-frequency sensory hearing loss (sharp cut-off at about 2 or 3 kHz), the latencies of wave V were always delayed, compared with those in normal-hearing subjects. In patients with gradual high-frequency sensory hearing loss, the latency of wave V was delayed according to the degree of hearing loss (as determined by pure tone audiometry) above 2 kHz. The data are interpreted as showing that the wave V latency is sensitive to a kind of recruiting phenomenon in the transduction process as well as being an index of the pressure wave travel time to the cochlear portion responsible for the elicitation of the BSR.
在12例经挑选的患有平坦型、低频型、重度高频型和渐进性高频型感觉神经性听力损失的患者中，研究了内耳病变对听性脑干反应（BSR）V波潜伏期的影响。在患有平坦型和低频型感觉神经性听力损失（梅尼埃病）的患者中，强度比其反应阈值高4-10dB时的V波潜伏期与听力正常的受试者大致相同。在患有重度高频型感觉神经性听力损失（在约2或3kHz处急剧截止）的患者中，与听力正常的受试者相比，V波潜伏期总是延迟。在患有渐进性高频型感觉神经性听力损失的患者中，V波潜伏期根据2kHz以上的听力损失程度（由纯音听力测定确定）而延迟。这些数据被解释为表明V波潜伏期对转导过程中的一种募集现象敏感，并且是压力波传播到负责引发BSR的耳蜗部分的时间指标。
