A noise barrier (also called a sound barrier,sound wall, noise wall, sound berm,or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls.
Sound barrier is a specially designed structure used to isolate noise, widely used in places with severe noise pollution such as highways, railways, airports,metros,subways and factories. The types of sound barriers vary depending on the place.
