Noise barriers, often termed as soundwalls, sound berms, or acoustical barriers, serve as exceptional sound insulation and noise reduction structures. They are meticulously crafted to shield residents and sensitive areas from the intrusive hum of noise pollution. When sound waves encounter an edge, they bend (downward) around it, a phenomenon seen at the apex of noise barriers. Adding to this complexity is refraction, the bending of sound rays when faced with an atmospheric gradient. This is particularly evident with influences such as wind shear and thermoclines, which introduce atmospheric inconsistencies.
