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. 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. 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. 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.
为了解深圳市木质家具制造、石材加工和特种设备制造行业噪声危害基本情况，为噪声危害防治提供依据。2019年8月，采用分层随机抽样方法，选取21家木质家具制造、15家石材加工和24家特种设备制造企业作为调查对象。通过职业卫生现场调查、噪声强度测量和职业健康检查数据收集等方法，对3个行业60家企业的噪声危害情况进行统计分析。木质家具制造、石材加工和特种设备制造企业的噪声检测点分别有154个、44个和113个，超标点数分别为101个、27个和78个，超标率分别为65.6%（101/154）、61.4%（27/44）和69.0%（78/113）。3个行业接触噪声的劳动者分别有1670人、172人和856人。其中，进行职业健康检查的分别有1198人、134人和703人，体检率分别为71.7%（1198/1670）、77.9%（134/172）和82.1%（703/856）。异常率分别为19.1%（229/1198）、51.5%（69/134）和37.8%（266/703）。高强度噪声工作环境、噪声暴露时间过长、个人防护用品佩戴不正确以及忽视职业健康检查是接触噪声人员听力损失的重要原因。
