摘要
目的:探讨生产性噪声对作业工人听力的影响。方法对某造船企业94名噪声作工人进行在岗期间纯音电测听检查,测听数据进行统计分析。结果听力损失37人(占受检人数的39.36%),其中轻度听力损失36人,中度听力损失1人。听力损失随工龄增加而升高,不同工龄组间听力损失比较有统计学意义(P<0.05)。结论听力损失随接触噪工龄的增加呈上升趋势。建议企业加强监督和管理,做好作业工人职业危害宣传教育和个人防护,建立和完善职业健康监护档案,控制职业性噪声聋发生。
Objective To investigate the ef ects of noise on workers productive hearing.Methods Pure tone audiometry examination for 94 shipyard workers during the post,Statistical analysis for audiometric data.Results 37 of hearing loss(accounting for 39.36%the number of subjects),in which 36 people with mild hearing loss and 1 person with moderate hearing loss.Hearing loss increases with length of service The comparasion among dif erent working-age groups was statistical y significant(<0.05).Conclusion Hearing loss increases with the exposure to noise seniority on the rise.Recommend that companies strengthen supervision and management,good education and personal protection for the workers exposed to occupational hazards,establish and improve occupational health record,prevent occupational noise deafness occuring.
