摘 要: | 目的 评估听力保护计划在金属制品行业的实施效果。 方法 选取28家金属制品企业推行听力保护计划, 内容包括噪声监测、听力测试、噪声控制、护听器使用和职工培训等五方面。 结果 听力保护计划实施2年后, 企业在噪声工程防护、工人护听器使用和工人培训教育方面均较计划实施前有改善, 作业场所噪声监测合格率有逐年上升趋势(P < 0.05)。实施听力保护计划2年后, 新上岗工人暂未出现高频标准听阈位移(HSTS), 已在岗接噪作业工人发生HSTS的共有6人, 占在岗工人总数2.27%。 结论 听力保护计划是一项综合的噪声防治策略, 能有效地防止职业性噪声聋的发生, 而管理者的重视和措施的落实是计划有效实施的保证。

Abstract: | Objective To assess the effectiveness of hearing protection program in the metal production industries. Methods Totally 28 metal production industries were introduced to hearing protection program, including noise measurement, audiometry, noise control, staff training, and the use of hearing protectors. Results After 2 years of implementation of the hearing protection program, the occupational health work, including the engineering protection against noise, the use of hearing protectors and the staff training were much better than before. The noise level at workplaces decreased and the compliance rate increased year by year(P < 0.05). Two years after the implementation of the hearing protection program, there was no case among new workers and 6 cases (accounting for 2.27%) among old workers who were diagnosed as high frequency standard threshold shift (HSTS). Conclusion The hearing protection program is a comprehensive strategy for prevention and control of noise at workplaces and can effectively prevent the occurrence of occupational hearing loss. The success of this program depend mainly on the attitude of the employer and leader team, and implementation in a persistent way. |
