A group of 74 miners, aged 19-35 years, exposed to industrial noise at average level of 82-88 dBA for 1.5 to 15 years were examined by means of otoacoustic emission (TEOAE). The group was divided into three subgroups, depending on the duration of noise exposure. The results obtained in miners were compared to the results of the control group nonexposed to noise at the workplace. Otoacoustic emission was weaker in subjects exposed to noise. Significant differences in responses were found in subgroups II and III as compared to controls. The results were compared to the data reported by other authors. The role of otoacoustic emission in providing information about dynamics changes in hearing impairment, depending on the duration of noise exposure, in subjects exposed to industrial noise, was emphasised.
一组74名年龄在19至35岁之间的矿工，暴露于平均强度为82 - 88分贝的工业噪声中1.5至15年，采用耳声发射（TEOAE）进行检查。根据噪声暴露时长，该组被分为三个亚组。将矿工组获得的结果与在工作场所未暴露于噪声的对照组结果进行比较。暴露于噪声的受试者耳声发射较弱。与对照组相比，亚组II和III的反应存在显著差异。将结果与其他作者报告的数据进行比较。强调了耳声发射在为暴露于工业噪声的受试者提供关于听力损伤动态变化信息方面的作用，该变化取决于噪声暴露时长。
