In this paper the train running noise level has been predicted with the theory of point sound source . the sound exposure level of a train set pass , equivalent continuous sound level and maximum sound level of a train set pass has been taken as estimate values , and some kinds of affixation attenuation on the course of noise propagation is considered , then the corresponding visual software has been developed . these make it convenient and precise to predict the noise level 本文从点声源的理论出发，对列车运行噪声进行预测计算，采用一列车通过时的单发暴露声级、时间特性的最大声压级和一定时间内的等效声级等作为噪声评价量，并考虑了噪声传播过程中的各种附加衰减，编制了相应的可视化软件，使噪声预测计算方便、准确。
	5.	At the same time this paper calculates the effect of train velocity on noise propagation , when mach number is 0 . 1 , sound velocity less effects on noise level ; when mach number is 0 . 4 , the difference value is about 2db whether to consider the sound velocity . so when the train velocity is not very high , the effect of sound velocity may not be considered 本文同时计算了列车运行速度对噪声传播的影响，当马赫数为0 . 1时，声音的传播速度对声级的影响是很小的，当马赫数为0 . 4时，考虑声速与不考虑声速影响的最大值的差值大约为2db左右，因此在列车速度不是很高的情况下可以不考虑声速的影响。
