A noise barrier (also called a soundwall, sound berm, sound barrier, or acoustical barrier) is an Sound insulation and noise reductionexterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. 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 in homogeneous atmosphere. Wind shear and thermocline produce such in homogeneities.
