摘要
以武汉市轻轨专线声屏障为研究对象,应用几何声学软件Raynoise对不同结构形式的声屏障降噪效果进行数值仿真,并通过文献中实验数据对比分析得出结论:同等高度Y形式声屏障整体降噪效果最好。
Applicating the Raynoise Software, noise reducing effects of different structure form are numerical simulated with the noise barrier of Light Rail Transit in wuhan. After analyzed the experiment data the result demonstrates that ＂Y＂ form noise barrier have the best noise reducing effect among all the same height types.
