摘要
目的:探讨噪声对铆工和试飞员听力的影响。方法:用整群抽样的方法在某飞机厂抽取703名飞机制造工人(其中铆工工人522名和试飞工人181名),进行现场卫生学调查和听力测试。结果:铆工高频损伤耳数和电测听各频率异常耳数与试飞员比较差异有统计学意义;两工种高频损伤耳数与语频损伤比较差异有统计学意义;两工种不同工龄段,高频损伤耳数与语频损伤比较差异有统计学意义;铆工中男性高频损伤与女性比较差异有统计学意义。结论:噪声对飞机铆工和试飞员听力损伤较大,主要表现高频听力损伤,听力损害程度与性别、接触噪声的时间有密切关系。
Objective： In order to evaluate the impact of aircraft-made noise on riveters＇ and test pilots＇ hearing in aircraftmade site. Methods： The sample of 703 aircraft- made workers （522 riveters, 181 test pilots） was chosen randomly and field hygeian survey in aircraft-made site were carried out, as well as heating test was done at the same time. Results： The results showed that the prevalence of HFNIHL in riveters, in various ranges from 0.25 kHz to 8 kHz and in work history were significantly higher than those of test pilots; and the prevalence of HFNIHL in riveters was different in different gender. Conclusion： The aircraft-made noise can dramatically injure workers＇ auditory system, especially showed in high frequence. The impact of industrial noise on workers＇ auditory system is obvious. There is close correlation between level of the injury and degree of how long exposure to noise as well as sex.
