目的了解地铁车辆运行噪音对地铁司机听力的影响,为地铁司机职业病防治提供依据。方法回顾性分析作者医院2013-02/2015-02月间受检的1034例地铁司机纯音听阈检测报告。结果 1034例受检者中听力下降者210例,发生率为20.31%。其中轻度听力下降者140例,中度听力下降者62例,重度听力下降者8例。结论地铁噪音可致司机听力下降,且工龄延长增加听力下降的发生率;定期纯音听阈检测,对于地铁司机听力损伤的防治,具有指导意义。
Objective To understand the impact of subway vehicle noise on the hearing of subway drivers and provide basis for prevention and control of occupational diseases in subway drivers. Methods A retrospective analysis was conducted on the pure tone audiometry of 1034 subway drivers tested in the author hospital from February 2013 to February 2015. Results In 1034 subjects, 210 cases of hearing loss were found, the incidence rate was 20.31%. Among them, mild hyponatremia in 140 cases, moderate hearing loss in 62 cases, severe hearing loss in 8 cases. Conclusion The subway noise can cause the hearing loss of the drivers, and the longer service life increases the incidence of hearing loss. The regular pure tone hearing threshold detection is instructive for the prevention and treatment of hearing loss of subway drivers.
