Road Noise Barrier Panel Highway No Fade Aluminum Sheet Sound Wall
Road sound barriers are structures used to reduce the propagation of road environmental noise. Soundproofing walls, noise barriers, or sound isolation walls are structures that achieve sound reduction effects by reflecting, absorbing, and blocking noise waves. When sound waves propagating in the air encounter sound barriers, reflection, transmission, and diffraction phenomena occur. Part of the sound waves will cross the top of the sound barrier and diffract to reach the sound receiving point, some will penetrate the sound barrier to reach the sound receiving point, and some will reflect on the surface of the sound barrier, thereby reducing the intensity of the sound waves reaching the sound receiving point.
