摘要
目的:通过对某车厂噪声作业人员听力损伤的4年追踪观察,了解噪声作业人员听力损伤情况的动态变化。方法对某车厂噪声作业人员体检资料进行筛选整理,选出同一年进厂且工作岗位相对固定的184位工人作为观察对象,对受检者逐年进行复查,连续4年追踪观察。结果2004年患病率为16.31%,2005年患病率为21.20%,2006年患病率为22.83%,2007年患病率为29.35%,2004年与2007年的听力损伤的差异有统计学意义(χ2=8.8853,P=0.0029),其余各年之间差异均无统计学意义(P>0.05)。结论某车厂噪声作业工人听力损害严重。听力损伤的程度与噪声暴露的年限存在剂量反应关系。
Objective To understand the status of heating impairment in workers exposed to noise. Methods There 184 workers exposed to noise were surveyed. Results The incidence of heating impairement was 16.31% in 2004,21.20% in 2005,22.83% in 2006,29.35% in 2007. There was significancely difference in the hearing impairment in 2004 compared to that of 2007 （x^2=8.8853,P〈0.05）. Conclusion Noise is harmful to the hearing capacity of workers and effecttive preventive measures be taken.
