目的 了解电子技术企业噪声作业工人听力损失的特点,为采取控制和消除职业性噪声聋的发生提供依据.方法 对两家电子技术企业进行职业卫生调查,以噪声作业车间495名工人为噪声组,以150例无职业危害作业工人为对照组,用常规方法测量每个工人的左右耳气导听阈,按照GBZ47-2007计算平均听阈和判定听力状态,比较两组工人听力状况,并对噪声组听力损失进行统计学分析.结果 噪声组、对照组听力损失检出率分别为14.9%和1.3%,两组比较,差异有极显著性(P< 0.01).噪声组中,接触非稳态噪声、稳态噪声工人的听力损失检出率分别为15.3%、12.5%,冲压、打磨和粉碎工种工人的听力损失检出率分别为15.3%、13.3%和11.8%,工龄为<5、5~、10~年组工人的听力损失检出率分别为8.2%、28.4%和38.3%,年龄为<25、25~、39~岁组工人的听力损失检出率分别为0.0%、17.9%和29.6%;不同工种、不同类型噪声接触工人的听力损失检出率比较,差异均无显著性(P> 0.05);x2趋势检验示,随着噪声作业工龄的增加、年龄的增加,听力损失检出率增加(P<0.01);逐步多因素Logistic回归分析显示,工龄、年龄是听力损失的独立危险因素.结论 电子技术行业高强度噪声引起作业人员听力损失,加强职业病防治管理措施,对降低职业性噪声聋的发生有重要意义.

Objective To provide support for the control and elimination of occupational noise-induced hearing loss by exploring the features of hearing loss in noise-exposed workers in electronic technology enterprises.Methods A survey on occupational health was conducted in two enterprises.495 workers exposed to environmental noise in the enterprises were studied as noise-exposed group and 160 workers with no noise exposure enrolled as control group.The air conduction thresholds were detected in both ears by routine methods.According to the criteria on GBZA9-2007, the average thresholds were calculated and the hearing status was determined and then was compared between the two groups.Hearing loss in noise- exposed group was analyzed.Results The detectable rate of hearing loss differed significantly between the noise-exposed group and in the control group( 14.9% vs.1.3%,P< 0.01 ).In the noise exposed group,the detectable rate was 15.3% in the workers exposed to non-stationary noise and 12.5% in those exposed to stationary noise; and it was 15.3% for those in charge of punching,13.3% for polishing,and 11.8% for grinding.The detectable rate was 8.2% for the group exposed to noise less than 5 years,8.3% for greater than 10 years,and 28.4% for in-between and it was 0.0%,17.9%,and 29.6% in different age groups of < 25 years,25 to 39 years,and > 39 years,respectively.The detectable rate did not differ significantly among different work types and among different sorts of noise ( P> 0.05 for all comparisons ).The x2 test revealed the detectable rate of hearing loss elevated with prolongation of noise exposure and an increase in age ( P< 0.01 for all comparisons ).Univariate analysis and multivariate logistic regression analysis showed length of work and age were the independent risk factors of hearing loss.Conclusions High-intensity noise causes hearing loss in workers in electronic technology enterprises.It is of importance to enhance the prevention and treatment of occupational diseases to reduce occupational noise-induced hearing loss.
