Highway Noise Barrier and Roadway Noise Barrier

Product Description

Noise Barrier

A noise barrier (also called a sound wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect sensitive land uses from noise pollution. Noise barriers are the most effective method of mitigating roadway, raolway, and industrial noise sources-- other than cessation of the source activity or use of source controls.
