摘要
目的:了解职业性噪声对工人听力的影响。方法:选择500名噪声作业工人及对其工作环境进行劳动卫生学调查,另将500名非噪声作业的人员设为对照组,分析2组研究对象听力水平的差异。结果:接触组的听损检出率为(22.4%),与对照组(4.2%)差异有显著性(χ2=71.81,P<0.01;听损检出率与噪声暴露水平和接噪工龄有关。结论:听损检出率随噪声暴露水平和接噪工龄的增加而增高。
Objective： To know the effect of noise on hearing loss of workers.Methods： 500 workers exposed to noise were seleted to do labour health investigation, meanwhih 500 workers were selected to be control, Differences in the level of hearing loss were analyzed.Remits： The results showed that the hearing loss incidences in noise group and control group were 22.4% and 4.2% respectively. It was significantly difference （ P 〈 0.01 ） ; The incidence was relatived with the working age and the level exposed to noise. Conclusions： Accompanying the increase of noise intensity exposure and the length of employment, the hearing loss was increased correspondendtly .
