清远市某钻石厂噪声作业工人听力检查结果

目的了解清远市某钻石厂噪声作业工人听力损失情况,为企业开展噪声危害控制提供依据。方法根据GBZ188-2007噪声作业体检规范,对该厂636名噪声作业工人进行纯音听阈测试检查。结果听力损失检出率为22.64%,不同年龄组听力损失差异具有统计学意义(χ2=14.31,P0.05),不同工龄组听力损失差异具有统计学意义(χ2=10.75,P0.05),听力损失与性别无直接关联(χ2=1.89,P0.05)。结论该厂噪声作业工人听力损失比较严重,应引起高度重视,采取积极有效的防治对策。

Hearing Test Results of Noise Exposed Workers in A Diamond Factory of Qingyuan City

Objective]To understand the hearing loss status among workers with noise exposure in a diamond factory of Qingyuan City,and provide evidence for implementation of noise hazard control in the enterprise.Methods]Pure tone audiometry was conducted on 636 workers exposed to noise according to GBZ188-2007 physical specification.Results]The detection rate of hearing loss was 22.64%,the difference between age groups was significant（χ2=14.31,P005）,the difference between workers with different service lengths was also significant（χ2=10.75,P0.05）.The hearing loss was not directly related with gender（χ2=1.89,P005）.Conclusion]The hearing loss of workers in this factory is serious,which should attract great attention and deserve positive and effective control measures.
