目的分析不同工龄、性别以及防护用品的使用情况与噪声作业工人听力损失的关系,为企业开展噪声危害控制提供依据。方法根据GBZ 188-2006噪声作业体检规范,对2008年北京市大兴区噪声作业工人500名健康检查的资料进行分析。结果不同暴露工龄组听力损失的发生率差异具有统计学意义(χ2=35.85,P<0.01);严重听力损失的发生率有随着接触噪声时间的增加而增加的趋势,使用防护用品听力损失的发生率以及严重程度明显低于未使用防护用品者(χ2=37.10,P<0.01)。听力损失的严重程度与性别无关(χ2=1.58,P>0.05)。结论听力损失的发生率及严重程度与工龄有关,使用防护用品能起到较好的防护效果。
Objective To analyze the relationship between different occupational ages, sex and the use of protective articles and the hearing loss of noise workers, and provide basis for enterprises to carry out noise hazard control. Methods Based on the GBZ 188-2006 noise operation examination standard, the data of 500 health checkup workers in Daxing District in Beijing in 2008 were analyzed. Results The incidence of hearing loss in different exposure group was statistically significant (χ2 = 35.85, P <0.01). The incidence of severe hearing loss increased with the increase of contact noise time, and the hearing loss The incidence and severity were significantly lower than those who did not use protective equipment (χ2 = 37.10, P <0.01). The severity of hearing loss has nothing to do with gender (χ2 = 1.58, P> 0.05). Conclusion The incidence and severity of hearing loss are related to length of service, and the use of protective equipment can play a good protective effect.
