【摘要】：目的研究使用听力保护用品的劳动者在噪声环境下作业对听力损失的影响。方法对某汽车制造企业从事噪声作业并佩戴听力保护用品的531名工人进行职业卫生调查和纯音听力测试。结果自觉听力差的9人(1.7%),经常耳鸣14人(2.6%),高频听力损失20人(3.8%),语频听力损失8人(1.5%),轻度噪声聋2人(0.4%),自觉听力损失和耳鸣的发生率与累积噪声暴露量、工龄均存在剂量-反应关系(P0.01),高频听力损失发生率与工龄存在剂量-反应关系(P0.05)。结论噪声暴露工人佩戴听力保护用品后仍会发生高频和语频的听力损失,需进一步提高工人的听力保护意识。
[Abstract]:Objective to study the effects of working in noise environment on hearing loss of workers using hearing protective equipment. Methods 531 workers who were engaged in noise work and wore hearing protective equipment in a car manufacturing enterprise were given occupational health care. Student survey and pure tone audition test. Results 9 people who felt poor hearing (. ). There were 14 patients with frequent tinnitus, 20 with high frequency hearing loss and 3.8 with hearing loss, 8 with speech frequency hearing loss and 1.5 with hearing loss, 2 with mild noise hearing loss and 0.4 with mild noise hearing loss. The incidence of conscious hearing loss and tinnitus was correlated with cumulative noise exposure and there was a dose-response relationship (P0.01). There was a dose-response relationship between the incidence of high frequency hearing loss and length of service. Conclusion the hearing loss of high frequency and speech frequency will still occur in noise exposed workers after wearing hearing protection equipment. It is necessary to further improve the awareness of hearing protection of workers.
