摘　　要：[目的]通过对深圳特区369名噪声作业工人听力损失情况的调查,了解该地区噪声环境下作业对劳动者听力的影响。[方法]采用横断面调查方法,以深圳市龙岗区部分企业噪声作业工龄1年以上的369名工人作为对象,进行职业卫生学调查。[结果]作业工人听力损失的发生率为76.42%;各工龄段的听力损失发生率的相比较差异无统计学意义(P﹥0.05);累积噪声暴露量与听力损伤发生率的不存在相关性(P﹥0.05)。[结论]深圳特区生产企业特点给噪声性听力损伤的相关研究带来了局限性,应研究更精确、更敏感的指标来评价噪声对听觉系统的影响。[Objective] To explore the influence of noise condition on the hearing loss of noise-exposed workers by the investigation the hearing loss of 369 workers under noise condition in Shenzhen special zone. [ Methods] By cross-sectional study, occupational hygienic investigation was carried out to 369 workers who have worked in noise-related enterprises for over a year in Shenzhen. [ Results ] The incidence of hearing loss was 76.42% ; There was no significant difference of the hearing loss among workers of different working ages （P 〉 0.05） ; There was no significant difference between cumulative quantity of noise exposure and the incidence of hearing loss （P 〉 0.05 ）. [ Conclusion ] The features of enterprises in shenzhen bring limitations to the research on the hearing impairment. Some more accurate and sensitive indicators should be taken to assess the influence of noise on the auditory systems.
