摘　　要：目的了解某钢帘线制品厂噪声作业人员听力损失状况,为采取有效的职业病危害防护措施提供依据。方法测试某钢帘线制品厂噪声作业人员双耳气导听阈,结果按GB/T 7582标准对听阈作年龄和性别修正,按年龄、接害工龄分组分析听力损失状况。结果该厂79个噪声监测点中,除7个点合格外,其余均不同程度超过GBZ 2.2-2007的要求;调查对象1 040人中,23人双耳高频平均听阈≥40 dB(HL)为观察对象,占总调查人数的2.21%;疑似职业性听力损伤18人。在同一年龄组,随接害工龄增长职业性听力损伤检出率有增高的趋势。结论钢帘线制品行业中,生产性噪声对作业人员听力损害较大,应控制生产环境噪声强度,做好作业人员个体防护及职业健康检查。[Objective] To understand the hearing loss of noise exposed workers in a steel cord products factory,and provide evidence for adopting effective protection measures against occupational hazards. [Methods]Binaural air conduction audiometry was performed on noise exposed workers,hearing results were modified according to age and sex with GB/T 7582 standard,analysis of hearing loss was based on age groups and service length groups. [Results]7 out of 79 noise monitoring sites points were qualified,the other exceeded national health standards GBZ 2.2-2007.Of 1 040 noise exposed workers,23 workers＇ binaural high frequency average hearing threshold ≥40dB（HL）,occupied 2.21% of total workers.18 were detected suspected occupational hearing loss.Occupational hearing loss showed a growing trend in detection rates increasing with the service length in the same age group. [Conclusion]It is important to control noise intensity in workplace and strengthen the personal protection of workers and occupational health examination,because great degree of hearing loss for noise is found in the steel cord products industry.
