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.

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.

Noise Barrier can be made of different materials, such as galvanized sheet, aluminum sheet, concrete, wood, Polycarbonate etc. More specification are as below.

Application scope

Sound barriers are mainly used along railways and highways.

Sound barriers are mainly used for sound insulation and noise reduction in transportation and municipal facilities such as expressways, elevated composite roads, urban light rail subways, and to control the impact of traffic noise on nearby urban areas. They can also be used for sound insulation and noise reduction in factories and other noise sources.

Sound barriers are divided into reflective sound barriers that are pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is made of more effective sound insulation. Most sound barriers use a combination of sound absorption and sound insulation products, which are characterized by targeted control of the generation and transmission characteristics of road noise. For example, the sound of friction between a car and the road or the friction between a locomotive and the track is in the lower part of the road, and the sound has the characteristic of diffracting through the upper part of the screen. Therefore, the design adopts a structure with sound absorption up and down and sound isolation in the middle, which can effectively reduce the diffraction of noise; a transparent reflective sound insulation board is used in the middle of the sound barrier, which can effectively interrupt the propagation path of sound waves. It also provides drivers and residents with a broad vision environment. In the field of architectural acoustics, through acoustic management, the reverberation time and indoor acoustic environment are controlled to meet the requirements of professional venues.
