Residential Outdoor Soundproof Acoustical Barriers for Noise AbsorbtionA 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.

Different Types of Noise Barrier

Noise Barrier can be made of different materials, such as galvanized sheet, aluminum sheet, concrete, wood, Polycarbonate etc. More specification are as below.1, Metallic Noise Barrier: Galvanized sheet( Anti-aging and Anti-corrosion)2, Aluminum Noise Barrier: Aluminum sheet(Anti-aging and Anti-corrosion)3, PVC Steel Noise Barrier: PVC steel material 4, Concrete Noise Barrier: High-strength cement or Light weight cement5, Cement Sawdust Noise Barrier: Cement and Bamboo6, Polycarbonate Noise Barrier: Polycarbonate 7, Acrylic Noise Barrier: Acrylic8, Glass Noise Barrier: Toughened Glass or Tempered laminated The size and color of these different noise barriers can all be customized. You can send us your drawing for customized shape or surface treatment.
