生产性噪声是人体有害因素之一。噪声不但影响正常作业,而且会影响人体健康。为了解管內噪声作业的危害程度,以便采取消声和隔声措施,保护作业人员的身体健康,提供依据。我站于81年6月～82年5月对管內47个单位进行了噪声调查与检测,结果如下: 一、一般情况管內47个生产厂段中有生产性噪声作业的是30个单位,131个作业点,有38种不同噪声源,接触 Productive noise is one of the harmful elements of the human body. Noise not only affects normal operation, but also affect human health. In order to understand the extent of the hazards of noise operation in the pipe so as to provide noise reduction and noise insulation measures and protect the health of workers, we will provide the basis. I conducted a noise investigation and test on 47 units in the pipeline between June 81 and May 2002. The results are as follows: I. General There are 30 units of production noise in 47 production sections in the pipeline , 131 operating points, 38 different noise sources, contact
