最近动物实验的惊人结果表明，噪音暴露可以导致高阈值听觉神经纤维的选择性丧失，而不会永久影响绝对灵敏度。这种耳蜗神经病变被描述为隐性听力损失，因为它不被认为是使用听力阈值的标准测量检测到的。隐性听力损失可能是人类的一种常见情况，可能是临床上听力正常的人所经历的一些感知缺陷的基础。有证据表明，即使在没有听力损失的情况下，噪音暴露史也与言语识别和时间处理困难有关。也有证据表明，临床听力正常的听者所经历的耳鸣与耳蜗神经病变有关，这是通过听觉脑干反应的波I来测量的。然而，到目前为止，噪音暴露、耳蜗神经病变和感知困难之间没有直接联系。动物实验也表明，在没有明显噪音暴露的情况下，衰老过程本身与听觉神经纤维的丧失有关。来自人类颞骨研究和听觉脑干反应测量的证据表明，这种形式的隐性损失在人类中很常见，可能具有感知后果，特别是在声音的时间方面的编码方面。隐性听力损失是一个潜在的重大健康问题，目前正在进行调查，以确定这种令人不安的状况的原因和后果。
Dramatic results from recent animal experiments show that noise exposure can cause a selective loss of high-threshold auditory nerve fibers without affecting absolute sensitivity permanently. This cochlear neuropathy has been described as hidden hearing loss, as it is not thought to be detectable using standard measures of audiometric threshold. It is possible that hidden hearing loss is a common condition in humans and may underlie some of the perceptual deficits experienced by people with clinically normal hearing. There is some evidence that a history of noise exposure is associated with difficulties in speech discrimination and temporal processing, even in the absence of any audiometric loss. There is also evidence that the tinnitus experienced by listeners with clinically normal hearing is associated with cochlear neuropathy, as measured using Wave I of the auditory brainstem response. To date, however, there has been no direct link made between noise exposure, cochlear neuropathy, and perceptual difficulties. Animal experiments also reveal that the aging process itself, in the absence of significant noise exposure, is associated with loss of auditory nerve fibers. Evidence from human temporal bone studies and auditory brainstem response measures suggests that this form of hidden loss is common in humans and may have perceptual consequences, in particular, regarding the coding of the temporal aspects of sounds. Hidden hearing loss is potentially a major health issue, and investigations are ongoing to identify the causes and consequences of this troubling condition.
