多次短时或一次长时间噪声可损伤内耳，造成暂时性或永久性阈移而致聋。噪声所引起的阈移有明显个体差异。TTS的恢复时间和阈移程度也有个体差异，可在2～4kHZ范围内移升IO～7OdB，恢复达原阈值的时间由6小时至15天以上。TTS的发生机制被认为是听器官疲劳或不应期。作者对Ic名
Repeated short-term or long-term noise can damage the inner ear, causing temporary or permanent threshold shift and deafness. Threshold shifts caused by noise have obvious individual differences. TTS recovery time and threshold shift also have individual differences in the range of 2 ~ 4kHZ increased IO ~ 7OdB, restore the original threshold time from 6 hours to 15 days or more. TTS mechanism of occurrence is considered to be organ fatigue or refractory period. Author of Ic name
