一、概述声屏障是位于声源与接收点之间的声遮档结构,使声波在传播过程中有一显著的附加衰减.声屏障的主要特点是采用不封闭的噪声防护结构,实现环境噪声控制.声屏障可以是各种结构的墙壁和建筑物等.声屏障是铁路环境噪声控制的措施之一.本文重点讨论设计方法和北京地区设置屏障问题.
An overview of the sound barrier is located between the sound source and the receiving point of the sound cover structure, so that sound waves in the propagation process has a significant additional attenuation.The main features of the sound barrier is the use of non-closed noise protection structure to achieve environmental noise control Sound barrier can be a variety of structures such as walls and buildings, etc. Sound barrier is one of the measures of railway environment noise control.This article focuses on the design method and the setting of the barrier in Beijing area.
