摘　　要：本文依据声学相似律理论，重点讨论了声学物理模拟实验的实现方法，并通过现场实验测量结果验证了模型实验测量结果。研究结果表明，采用物理模拟实验方法研究、评价铁路噪声，尤其是建筑群中的声场分布是可行和可靠的。Based on the acoustical principle of similarity,the realization way of the acoustical physical simulation experiment was discussed,which was testified by measurement results.The results showed that using the physical simulation experiment to investigate and assess rail noise was effective and reliable,especially for the distribution of sound field in the building.

关 键 词：铁路噪声 物理模拟 实验方法 环境噪声评价
