| 摘 要： | 报道了油田勘探开发作业工人噪声暴露及听力损伤调查结果。运用年等效Ａ声级作为评价不同工作日间歇暴露噪声工作的噪声暴露剂量，显示出油田工人的高频听损发生率和语频听损发生率均与年等效Ａ声级有良好的相关关系。探讨了年等效Ａ声级在噪声危害调查中的应用。

| Abstract: | Results of noise exposure and hearing loss of oilfield workers were reported.The year equivalent A|weighted sound pressured level(YEASPL)has been used in analyzing the noise exposure of oilfield workers intermittently exposed to noise in different working days.It was found that there existed a satisfactory correlation between the rate of hearing impairment and the YEASPL(R=0^99, P <0^01).The possibility of applying the YEASPL in survey of noise exposure was also discussed. |
