    Abstract:
    Objective: To understand the basic situation of noise hazards in wood furniture manufacturing, stone processing and special equipment manufacturing industries in Shenzhen City, and to provide basis for preventing and controlling noise hazards. Methods: In August 2019, stratified random sampling ws used to select 21 wood funiture manafacturing, 15 stone processing and 24 special equipment manufactruing as survey object. Through the methods of occupational health field investigation, noise intensity measurement and occupational health examination data collection, the noise hazards of 60 enterprises in three industries were statistically analyzed. Results: There were 154, 44 and 113 noise detection points in wood furniture manufacturing, stone processing and special equipment manufacturing enterprises, and 101, 27 and 78 out of standard points respectively, and the exceeding standard rates were 65.6% (101/154) , 61.4% (27/44) and 69.0% (78/113) , respectively. There were 1670, 172 and 856 workers exposed to noise in the three industries. Among them, 1198, 134 and 703 people had taken occupational health examination. The physical examination rates were 71.7% (1198/1670) , 77.9% (134/172) and 82.1% (703/856) , respectively. The abnormal rates were 19.1% (229/1198) , 51.5% (69/134) and 37.8% (266/703) , respectively. Conclusion: High intensity noise working environment, too long noise exposure time, incorrect wearing of personal protective equipment and neglect of occupational health examination are important reasons for hearing loss of noise exposed personnel. 目的： 了解深圳市木质家具制造、石材加工和专用设备制造行业噪声危害的基本情况，为预防和控制噪声危害提供依据。 方法： 于2019年8月，采用分层随机抽样法，选取2018年2至11月深圳市木质家具制造企业21家、石材加工企业15家和专用设备制造企业24家共60家企业为调查对象，通过职业卫生现场调查，作业场所噪声强度的测量、收集职业健康体检资料等方法对三个行业共60家企业的噪声危害进行统计学分析。 结果： 木质家具制造、石材加工和专用设备制造企业噪声检测点数分别为154、44和113个，其中点位超标率分别为65.6%（101/154）、61.4%（27/44）和69.0%（78/113）。三个行业的噪声接触人员分别为1 670、172、856人，体检率分别为71.7%（1 198/1 670）、77.9%（134/172）和82.1%（703/856），听力异常率分别为19.1%（229/1198）、51.5%（69/134）和37.8%（266/703）。 结论： 高强度的噪声作业环境、接噪时间过长、不正确佩戴个人防护用品和职业健康体检不受重视是导致接噪人员听力损失的重要原因。.
