统计能量法预测铁路声屏障的降噪效果

Predication of Efficiency of Railway Anti-Noise Barriers with Statistical Energy Analysis Method

用统计能量分析 (简称SEA)来预测铁路声屏障的降噪效果 ,并针对某一有声屏障的铁路段进行SEA建模。模型包含列车车体与声屏障之间的声空间以及声屏障 2个子结构。

Statistical energy analysis (SEA) is used to predict the efficiency of railway anti noise barriers. An analytical model is proposed, which consists of two sub constructions. The result obtained with the proposed model is similar to that with conventional empirical method.
