Product Description
Highway Road Using Best Fence for Sound Barrier
A noise barrier (also called a soundwall, sound berm, sound barrier, 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.

Theory of Design
The acoustical science of noise barrier design is based upon treating an airway or railway as a line source. The theory is based upon blockage of sound ray travel toward a particular receptor; however, diffraction of sound must be addressed. 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.Sound Absorption CoefficientFrequency(Hz)100125160200250315400500630Sound Absorption Coefficient a0.210.240.360.410.640.810.981.020.96Frequency(Hz)80010001250160016002500315040005000Sound Absorption Coefficient a0.910.961.051.121.121.101.040.990.94
