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。
