一前言控制交通噪声是城市环境保护工作的一个重要组成部份。特别对于大、中城市,有效地监视交通噪声,从而采取相应的管理方法以改善交通车流,加速城市“血脉”的运动,并降低环境中的噪声污染,显得十分重要。在城市交通枢纽,例如车站、机场、码头和主要交车路口,实时地测量和显示出噪声级,供分析处理,是监视交通噪声的一种有效手段。同济大学声学研究室于1982年5月受上海市环境监测中心的委托,根据上述要求研究试制“城市交通噪声大屏幕数字显示自动监测
Preface Controlling traffic noise is an important part of urban environmental protection. Especially for large and medium-sized cities, it is very important to effectively monitor traffic noise so as to adopt appropriate management methods to improve traffic flow, speed up the city’s blood flow and reduce noise pollution in the environment. Measuring and displaying noise levels in real-time for traffic analysis at urban transport hubs such as stations, airports, terminals and major intersections is an effective means of monitoring traffic noise. Acoustic Laboratory of Tongji University in May 1982 by the Shanghai Environmental Monitoring Center commissioned, according to the above requirements of trial production of "urban traffic noise large-screen digital display automatic monitoring
