A noise barrier, also known as a soundwall, sound berm, sound barrier, or acoustical barrier, is meticulously engineered as an exterior structure to provide sound insulation and noise reduction. Its primary function is to shield residents in sensitive areas from the harmful effects of noise pollution. The interaction of sound waves with these barriers results in a fascinating phenomenon where waves bend downward upon encountering the barrier's apex. Additionally, the complexity of sound behavior is further enhanced by refraction, a process where sound rays bend within an atmosphere that is not uniform, often due to factors like wind shear and thermocline variations.
