摘　　要：运行速度是影响铁路列车运行噪声特性的重要因素之一。通过对列车运行噪声的现场测量,采用统计分析的数据处理方法,确定了基本条件下客运、货运列车运行噪声频谱特性与运行速度的关系。Train running speed is one of the important factors affecting railway noises. Statistic method was used to analyze the noise data of running trains measured on the spot, and relationship between running speeds of passenger or freight trains and frequency character of the trains running noise under basic condition was determined in this paper.
