Abstract

The effects of auditory fatigue, using a temporary threshold shift (TTS) paradigm, on cochlear microphonics (CM) and on auditory brainstem-evoked potentials (ABEP), were studied in normal-hearing subjects during the development of permanent threshold shift (PTS). Behavioral threshold shifts were accompanied by different effects on CM and on ABEP, as PTS was gradually induced by occupational noise. Measures of the effect of increasing stimulus rate (ISR) on ABEP revealed decreased latency shifts during auditory fatigue. ABEP proved useful in early detection of changes in the auditory system, resulting from exposure to noise. In addition, this study further supports the suggestion that TTS acts as a peripheral attenuator of the effect of ISR on the central auditory pathway.

摘要

采用暂时性阈移(TTS)范式,在正常听力受试者永久性阈移(PTS)发展过程中,研究了听觉疲劳对耳蜗微音电位(CM)和听觉脑干诱发电位(ABEP)的影响。随着职业噪声逐渐诱发PTS,行为阈移对CM和ABEP产生了不同影响。增加刺激速率(ISR)对ABEP影响的测量结果显示,听觉疲劳期间潜伏期变化减小。事实证明,ABEP有助于早期检测因接触噪声而导致的听觉系统变化。此外,本研究进一步支持了以下观点,即TTS可作为ISR对中枢听觉通路影响的外周衰减器。
