Sound Barrier Road Noise Barrier Sheet Highway Soundproof Panel
A noise barrier (also called a soundwall, sound berm, sound barrier, or acoustical barrier) is an Sound insulation and noise reductionexterior structure designed to protect inhabitants of sensitive land use areas from noise pollution.
Sound waves bend (downward) when they pass an edge, such as the apex of a noise barrier. Further complicating matters is the phenomenon of refraction, the bending of sound rays in the presence of an inhomogeneous atmosphere. Wind shear and thermocline produce such inhomogeneities

Standard height: 2,000mm, 2,500mm, 3,000mm and space between poles 1,000mm, 2,000mm and 2,500mm. it is available upon customer request.Steel structure and sound insulation screen consist of the sound barrier. The design already takes fully consideration of express way and subway's wind load, transportation traffic's striking security and all days' chemical proof in the open air.
Noise barrier is mainly used for sound insulation and noise reduction in transportation and municipal facilities such as expressways, elevated composite roads, urban light rail and subways, and to control the impact of traffic noise on nearby urban areas. It can also be used for sound insulation and noise reduction in factories and other noise sources.
