A noise barrier, also known as a soundwall, sound berm, sound barrier, or acoustical barrier, is an expertly engineered exterior structure. Designed to safeguard inhabitants of sensitive land use areas from the pervasive threat of noise pollution, this innovative solution significantly enhances the quality of life. Sound waves, with their propensity to bend (downward) as they pass an edge, like the apex of a noise barrier, are deftly manipulated by this technology. The sophisticated phenomenon of refraction, which involves the bending of sound rays in an irregular atmosphere, is skillfully managed, even in the face of challenges posed by natural elements like wind shear and thermocline, which contribute to atmospheric inhomogeneities.
