观察到新入厂纺织女工第 1年高频听力损伤患病率较高 ,第 2年下降 ,第 3年上升 (恢复至第 1年水平 )。讨论了造成这样现象各种可能的原因 ,并提出早期噪声暴露阶段的听阈测定值作为基线数据在噪声防治工作中的意义值得进一步探讨
It was observed that in the first year, newlywed textile women workers had a higher prevalence of high-frequency hearing loss, a decrease in the second year and an increase in the third year (restored to the level of the first year). This paper discusses the various possible causes of such a phenomenon and proposes that the measurement of the hearing threshold at the early stage of noise exposure be used as baseline data in the prevention and control of noise.
