Click-evoked auditory brainstem responses were measured in a patient with high-frequency conductive hearing loss. As is typical in cases of conductive hearing loss, Wave I latency was prolonged beyond normal limits. Interpeak latency differences were just below the lower limits of the normal range. The Wave V latency-intensity function, however, was abnormally steep. This pattern is explained by the hypothesis that the slope of the latency-intensity function is determined principally by the configuration of the hearing loss. In cases of high-frequency hearing loss (regardless of the etiology), the response may be dominated by more apical regions of the cochlea at lower intensities and thus have a longer latency.
对一名高频传导性听力损失患者进行了点击诱发听觉脑干反应测试。正如传导性听力损失病例中的典型情况一样，波Ⅰ潜伏期延长至正常范围之外。峰间期差异略低于正常范围的下限。然而，波Ⅴ潜伏期-强度函数异常陡峭。这种模式可以用以下假设来解释：潜伏期-强度函数的斜率主要由听力损失的形态决定。在高频听力损失的情况下（无论病因如何），较低强度时反应可能主要由耳蜗更顶端的区域主导，因此潜伏期更长。
