随着铁路运输事业的不断发展,机车车辆噪声对环境的污染公害已越来越被人们所关注。国际标准化组织已于1975年提出“3095声学——铁路车辆辐射噪声的测量”。根据我国对制定标准的要求,凡是国际上已有的标准,我们经过验证后即可使用。我们按照这个精神于1982～1983年在路内几条于线的一些区段以及北京环城地下铁道进行了验证工作。一方面是为了评价我国各种机车车辆辐射噪声的水平及比较各种机车车辆的声学特性和噪声控制效果。另一方面是为了保护沿线广大居民的健康,必须有统一的机车车辆辐射噪声测试方法,以便监督环境噪声标准的实施。
With the continuous development of railway transport, the environmental pollution caused by the noise of rolling stock has attracted more and more attention. International Organization for Standardization in 1975 proposed “3095 Acoustics - Measurement of railway vehicle radiation noise.” According to China’s requirements for the development of standards, all the internationally accepted standards, we can use after verification. In accordance with this spirit, we conducted some verification work in a few sections along the road from 1982 to 1983 and the Beijing metro ring. On the one hand, it is to evaluate the level of radiation noise of various locomotive and rolling stock in China and to compare the acoustic characteristics and noise control effects of various locomotive and rolling stock. On the other hand, in order to protect the health of the residents along the line, there must be a unified test method of radiation noise of rolling stock in order to supervise the implementation of environmental noise standards.
