Sound barriers are mainly used for sound insulation and noise reduction of highways, highways, elevated composite roads and other noise sources. It is divided into a reflective sound barrier with pure sound insulation, and a composite sound barrier with a combination of sound absorption and sound insulation. The latter is a more effective sound insulation method. Refers to the wall-type structures installed beside railways and highways to reduce the impact of traffic noise on nearby residents. Soundproof walls are also known as sound barriers. A facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the impact of noise in a certain area where the receiver is located. Such a facility is called a sound barrier. Divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial boundary noise barriers, roads and highways are the places where the most types of sound barriers are used
