Corrosion Resistant Highway Noise Walls 40mm-110mm Railway Noise Barriers

Highway Noise Absorb Fence Barrier

Product description

An acoustic barrier is a device inserted between the source and the receiver that causes a significant additional attenuation of sound wave propagation, thereby reducing the impact of noise in the area where the receiver is located.The design of sound barrier takes into full consideration the wind load of viaduct, urban light rail and subway, the impact of traffic vehicles and the all-weather open air corrosion protection.
