【摘要】 目的了解噪声对汽车制造工人听力的影响,旨在探讨听力保护措施与筛查重点防护人群。方法依据相关规范标准对393名汽车制造企业接触噪声作业工人听力损伤进行调查分析,并与不接触噪声的对照组工人进行对比分析。结果接触平均噪声89.8dB(A)工人听力损伤(耳)检出率为35.1%,显著高于对照组,检出率随工龄增长而增加,并且脉冲噪声接触工人听力损伤(耳)检出率高达57.1%,高于稳态噪声接触组。结论该人群听力损伤检出率较高,噪声危害应采取治理、个体防护、加强监护的综合措施,调试工因工作原因不能佩戴耳塞防护,是噪声监护的重点人群。更多还原

【Abstract】 [Objective]To investigate the influence of noise on the automobile mill workers, explore the hearing protection measures and screen the key population for protection. [Methods] Analysis was made on the hearing loss of 393 noise-exposed automobile mill workers according to relevant regulations and standards; comparison was made with that of the control. [Results] The detection rate of hearing loss was 35.1% among the workers who were exposed to the noise with an average level of 89.8 dB (A), which was significantly higher than that of the control; the detection rate increased with the length of service; the detection rate of the impulse noise group was 57.1%, which was higher than that of the stable noise group. [Conclusion]The detection rate in this population is quite big; comprehensive measures should be taken for the prevention including managing, individual protection and surveillance; the debugging workers are the key population for protection since they can’t wear ear plug at work.更多还原
