During the construction of the highway, it needs to pass through the city area. In order to reduce the influence of noise on the surrounding environment, sound barriers are usually built on both sides of the highway. The sound barrier is a kind of acoustic barrier plate between the noise source and the sound receiving point. By inserting a facility between the sound source and the receiver, the sound wave propagation has a significant additional attenuation, so as to weaken the noise influence in a certain area where the receiver is located. The sound barrier is mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources.
