【摘要】：目的探讨噪声接触时间和噪声强度对噪声作业工人听力损失的风险程度。方法采用回顾性队列研究分析广东省中山市1 411名噪声作业工人连续3年纯音气导听阈和噪声监测数据。结果 1 411名中山市噪声作业工人2012—2014年双耳高频听阈存在时间主效应和噪声强度主效应(P0.05)。噪声作业工人2012、2013、2014年的双耳高频听阈分别为(30.88±7.21)、(30.57±6.91)、(30.37±7.21)d BHL,2013年与2012年相比,噪声作业工人双耳高频听阈升高(P0.05),2014年与2013年相比,双耳高频听阈无差异(P0.05);不同噪声强度双耳高频听阈不同(P0.05),≥88 d B(A)噪声强度的工人双耳高频听阈最高,2012—2014年分别为(32.83±9.45)、(32.20±9.11)、(32.22±9.52)(d BHL)。结论噪声接触时间和噪声强度与噪声接触工人双耳高频听阈损失存在剂量-反应关系。
[Abstract]:Objective to investigate the risk of noise exposure time and noise intensity on hearing loss in noise exposed workers. Methods A retrospective cohort study was conducted to analyze the hearing threshold of 1,411 noise workers exposed to noise for 3 consecutive years in Zhongshan City, Guangdong Province. Results there were significant temporal effects and noise intensity effects in 2012-2014 among 1 411 noise exposed workers in Zhongshan City (P < 0. 05). The hearing thresholds of noise workers in 2014 were 30.88 卤7. 21 卤6. 91 卤30. 37 卤7. 21 d BHLs in 2013 compared with 2012. In noise exposed workers, the high-frequency threshold of binaural hearing increased (P0.05), compared with 2013, in 2014, There was no difference in the binaural high frequency hearing threshold (P0.05). The highest hearing threshold for workers with different noise intensity (P0.05, 鈮，
