摘要
通过分析比较 ,确定了以单节车辆运行的声暴露级LSEO 作为铁路列车运行噪声预测的基本源强参量 ,并给出了确定LSEO 的计算方法和测量方法。在现场试验的基础上 ,确定了客、货列车在基本运行和线路条件下的源强参数值 。
Through careful analysis and comparing,we established an intensity parameter of noise source of running trains,which was presented as sound exposure level(L SE0)of an individual car.Methods to calculate and measure the parameter(L SE0)was also introduced in this paper.Based on the experiment on-site test,this parameter of running trains(passenger and freight train)under main condition of running and line was determined as well.
