摘要
铁路列车运行噪声的水平指向性是铁路列车噪声辐射的重要特性之一。在实际测量列车运行噪声的基础上 ,通过理论分析和曲线比较的方法 。
The horizontal direction of train running noise is a important character of train radiating noise.This paper analyses the frequency character on horizontal direction of train running noise,based on the data of spot measuring,theoretical analysis and comparison between theoretical profiles and measuring profiles.
