目的通过对汕头市某纺织厂噪声作业工人听力损伤情况的调查,了解该企业噪声环境下作业对劳动者听力的影响,为制定职业病防控措施提供依据。方法选取2011—2013汕头市某纺织厂的663名接触噪声作业工人作为调查对象,进行听力测定,结合职业卫生调查和作业环境中噪声监测资料对听力测定结果进行分析。结果 3年平均噪声作业工人听力损伤检出率为16.74%;听力损伤在不同年份和不同性别间比较,差异无统计学意义;不同工龄组听力损伤比较,差异有统计学意义。随着年龄和工龄的增加,工人的听力损伤发生率逐渐升高。结论企业应充分重视工作场所噪声的危害,加强噪声的治理与防护,同时应进行职业健康教育,提高工人自我保护意识。
Objective To investigate the hearing impairment of noise workers in a textile factory in Shantou, understand the impact of homework on workers’ hearing under noisy environment, and provide evidence for the prevention and control of occupational diseases. Methods 663 workers exposed to noise in a textile mill in Shantou City during the period of 2011-2013 were selected as the survey subjects for audiometry. The results of audiometry were analyzed with occupational health surveys and noise monitoring data in operating environment. Results The detection rate of hearing loss was 16.74% for three-year average noise workers. There was no significant difference in hearing impairment between different years and different sexes. The hearing loss in different age groups was significantly different. With the increase of age and seniority, the incidence of hearing loss in workers gradually increases. Conclusion Enterprises should pay full attention to the hazards of noise in the workplace, strengthen the management and protection of noise, and at the same time should carry out occupational health education and raise their awareness of self-protection.
