车间噪声级的大小是评价工人操作区声环境优劣的主要依据.如何确定车间噪声级?目前尚无切实可行的方法可供工厂设计人员使用,因而很难判断正在设计中的车间(或站房)建成投产后的噪声级究竟有多大、是否需要采取减噪措施、以及车间噪声对厂区环境的影响程度等问题.本文根据大量调查资料和实测数 The size of the workshop noise level is the main basis for evaluating the sound environment of the workers operating area How to determine the noise level of the workshop? There is currently no practical method for factory designers to use, it is difficult to judge the workshop under design (or station Room) put into operation after the noise level is how much, whether the need to take noise reduction measures, as well as workshop noise impact on the plant environment and other issues.This paper based on a large number of survey data and the measured data
