Noise barriers, also known as soundwalls, sound berms, or acoustical barriers, are expertly crafted exterior structures designed to shield inhabitants in sensitive areas from the intrusive clamor of noise pollution. These structures work ingeniously by bending sound waves when they encounter an edge, such as the peak of a noise barrier. The challenge is further heightened by the phenomenon of refraction, where sound rays bend in an atmosphere that isn't uniform, often caused by wind shear and thermocline effects that produce such irregularities.
