道路交通声屏障降噪设计方案研究

Research on Design Scheme for Noise Reduction through Road Traffic Sound Barrier

设置声屏障是降低道路交通噪音的一种有效手段。阐述了道路交通工程中声屏障降噪原理,详细介绍了声屏障插入损失的影响因素和计算方法,结合具体工程实例分析了声屏障高度及长度对插入损失的影响,并针对现场条件受限、无法通过声屏障完全解决噪声超标问题的情况,提出了其他辅助降噪措施。

The setup of the sound barrier is an effective means for reducing the traffic noise. The principle ofnoise reduction through the sound barrier in road traffic engineering is elaborated. and the influencing factors andcalculation method for the insertion loss of the sound barrier are introduced in detail. In combination with specificproject case. the influence of the sound barrier height and length on the insertion loss is analyzed. and otherauxiliary measures for noise reduction are put forward by aiming at the limitation of site condition. failure to fullysolve the problem of excessive noise through the sound barrier and so on.
