Noise barrier is mainly used for sound insulation and noise reduction in transportation and municipal facilities such as expressways, elevated composite roads, urban light rail and subways, and to control the impact of traffic noise on nearby urban areas. It can also be used for sound insulation and noise reduction in factories and other noise sources.
