Rail Transit Sound Barrier
Sound barriers are mainly used for sound insulation and noise reduction in highways, expressways, elevated composite roads, and other noise sources. It can be divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and insulation, with the latter being a more effective sound insulation method. It refers to wall structures set up on the sides of railways and highways to reduce the impact of driving noise on nearby residents. Soundproofing walls are also known as sound barriers. Inserting a facility between the sound source and receiver to significantly attenuate the propagation of sound waves, thereby reducing the noise impact within a certain area where the receiver is located, is called a sound barrier. Divided into traffic noise barriers, equipment noise attenuation noise barriers, industrial plant noise barriers, and highways, these are the places where various types of noise barriers are most commonly used.
