摘要
目的探讨噪声暴露对作业场所工人听力损失的影响。方法采用横断面调查,对惠州市直属五金、印刷、食品、电子等行业8个工厂进行噪声作业场所调查,并对噪声作业工人进行职业卫生调查及纯音听力测定。另选择相应办公室不接触噪声的职工164人作为对照组。结果听力损失率随着接触噪声的工龄增加而增高,随着接触噪声强度的增加,呈现出明显的时间剂量-反应关系。听力损失率接触毒物和噪声组明显高于噪声组(P<0.05)。结论噪声强度、接噪工龄是影响作业工人听力的主要因素,毒物与噪声联合作用加重听力损害。
[Objective]To study the effect of noise exposure on hearing loss in workers of the work places.[Methods]Using cross-sectional study,the noise exposure of the work places was investigated in 8 factories（including hardware industry,printing industry,food industry and electronic industry） directly under Huizhou city,and occupational health investigation and pure tone audiometry were conducted in workers exposed to noise.164 office employees who did not have contact with noise were chosen as the control group.[Results]The hearing loss rate increased with the working age exposed to noise and noise intensity,which showed an obvious time-dose-response relationship.The hearing loss rate of the noise and toxicant exposure group was significantly higher than that of the noise exposure group（P0.05）.[Conclusion]The noise intensity and working age exposed to noise are the main factors that influence workers＇ hearing,and toxicant combined with noise could aggravate the hearing loss.
