What was found is that when people are exposed to a certain level of noise every day for a certain duration, they're going to have a certain degree of hearing loss on average.
我们发现，当人们长期的暴露在某一特定噪音水平环境中，他们平均都会有一定程度的听力丧失。
Results The average equivalent sound level and the detectable rate of workers hearing loss were exponential positive correlation, the coefficient of correlation r was 0 812 45.
结果听损检出率随平均等效声级的增加而呈明显的增加趋势，平均等效声级与噪声作业人员的听损检出率呈密切的指数正相关关系（相关系数r为0 812 45 ）。
Conclusion ECG and hearing in workers could be affected with long-term exposure to medium low intensity noise, even if the exposure average level was lower than the limited level of hygienic standard.
结论作业人员长期在平均噪声强度低于卫生标准下工作，仍可有一定程度的心电图改变和听力损失。
