摘要
能够获取铁路服役期间稳定持续的噪声数据是分析铁路噪声机理、噪声源及开展噪声防治工作的前提。文中对德国铁路最新使用的噪声在线监测系统及噪声地图方法进行了介绍,并对两种方法的输出数据形式进行解析。借助该方法,德国铁路可持续收集大量稳定的服役期噪声数据。针对我国铁路在噪声数据收集方面的不足,给出相应的建议。
It is a prerequisite to analyze the mechanism and source of railway noise and to carry out noise prevention and control work to obtain stable and continuous noise data during railway service.This paper introduces the latest on-line noise monitoring system and noise map method of German railway,and analyzes the output data form of the two methods.By means of this method,German railway can collect a large number of stable noise data sustainably.In view of the shortage of railway noise data collection in China,some Suggestions are given.
