摘要
目的探讨戴耳机听音乐对噪声作业工人高频噪声性听力损失(NIHL)的影响。方法采用判断抽样方法,以某汽车制造厂651名男性噪声作业工人为研究对象,对其进行个体噪声接触水平和纯音听阈测试;根据研究对象下班后戴耳机听音乐的频率分为低、中和高频率使用耳机组,分别有60、436、155人。分析戴耳机听音乐联合职业性噪声接触对高频NIHL的影响。结果研究对象高频NIHL检出率为31.3%(204/651)。3组人群高频NIHL检出率由低到高依次为低、中和高频率使用耳机组(P<0.01);高频率使用耳机组人群高频NIHL检出率分别高于低和中频率使用耳机组(43.2% vs 25.0%,43.2% vs 28.0%,P<0.01)。多因素Logistic回归分析结果显示,在排除年龄、噪声作业工龄、噪声接触水平、佩戴防噪耳塞等混杂因素的影响后,戴耳机听音乐是噪声作业工人高频NIHL的危险因素(P<0.01);戴耳机听音乐的频率越高,发生高频NIHL的风险越大。结论噪声作业工人下班后戴耳机听音乐与职业性噪声接触对其发生高频NIHL具有协同作用。
Objective To explore the effect of wearing earphone to listen to music on the high-frequency noise-induced hearing loss(NIHL)in noise-exposure workers.Methods A total of 651 male noise-exposure workers in an automobile manufacturer were selected as study subjects by using judgment sampling method.The level of noise exposure in the individuals and the pure tone hearing threshold were tested.According to the frequency of wearing earphone to listen to music after work,the subjects were divided into low-,medium-and high-frequency earphone-using groups,with 60,436 and 155 workers in each group,respectively.The effects of wearing earphone to listen to music combined with occupational noise exposure on high-frequency NIHL were analyzed.Results The high-frequency NIHL detection rate of the study subjects was 31.3%(204/651).The detection rate of high-frequency NIHL in these three groups from low to high was low-,medium-and high-frequency earphone-using groups(P<0.01).The detection rate of high-frequency NIHL in the high-frequency earphone-using group was higher than that of the low-and medium-frequency earphone-using groups(43.2%vs 25.0%,43.2%vs 28.0%,P<0.01).Multivariate logistic regression analysis showed that wearing earphones to listen to music was a risk factor for high-frequency NIHL in noise-exposure workers(P<0.01)after eliminating the influence of confounding factors such as age,length and level of noise-exposure,and wearing anti-noise ear plugs.The higher frequency of wearing earphone to listen to music,the higher risk of high-frequency NIHL.Conclusion Wearing earphone to listen to music after work and occupational noise exposure had a synergistic effect on high-frequency NIHL in noise-exposure workers.
