以前高频噪声对作业工人听力影响的研究报道大多数是关于纺织、运输、石油钻井、煤矿方面的,石化企业空分车间噪声对工人听力的影响报道甚少。为探讨石化企业空分车间噪声对作业工人听力的影响,作者于1995年4月至10月对燕山石化公司某空分车间进行现场劳动卫生学调查。 1 一般情况及方法 1.1 接触组为某空分车间直接接触噪声的空压机、氧压机、氮压机岗位工人61名,男37名,女24名;每天接触噪声时间约2h,年龄19至43岁,平均年龄29.9岁;工龄1至21年,平均工龄10.6年。对照
In the past, most reports about the influence of high-frequency noise on workers’ hearing had few reports on the impact of noise in the air separation plant of workers and workers in the textile, transportation, oil drilling and coal mining industries. In order to investigate the impact of noise in the air separation plant of petrochemical enterprises on the hearing ability of workers, the author conducted an on-site labor hygiene survey of an air separation plant in Yanshan Petrochemical Company from April to October 1995. 1 General Situation and Methods 1.1 The contact group is 61 air-conditioners, oxygen compressors and nitrogen compressors, with 37 men and 24 women. The daily exposure time is about 2 hours and the age is 19 To 43 years old, with an average age of 29.9 years; length of 1 to 21 years, the average length of service of 10.6 years. Control
