Three examinations, including cochlear microphonics (CM) to 99/s 1-kHz tones and auditory brainstem evoked potentials (ABEP) to 10/s and 55/s clicks, as well as psychoacoustical tests, were performed on 31 normally hearing subjects, exposed to occupational noise for over a year. The results showed prolongation of the absolute latency of peaks I, III and V, without significant changes in interpeak latency differences (IPLD) or CM latency. The site affected by increasing stimulus rate, giving rise to increased IPLD, appears to be central rather than cochlear. The efficacy of increased stimulus rate in detecting noise-induced auditory changes was higher than achieved applying the 10/s click rate.
对31名正常听力、已接触职业噪声一年以上的受试者进行了三项检查，包括对99次/秒1千赫兹纯音的耳蜗微音电位（CM）、对10次/秒和55次/秒短声的听性脑干诱发电位（ABEP）以及心理声学测试。结果显示，波峰I、III和V的绝对潜伏期延长，而峰间潜伏期差异（IPLD）或CM潜伏期无显著变化。受刺激率增加影响、导致IPLD增加的部位似乎是中枢而非耳蜗。增加刺激率在检测噪声诱发听觉变化方面的效果高于采用10次/秒短声率时的效果。
