1. Product description

Sound barrier is widely used in traffic noise insulation facilities. In order to block the direct sound between the source and the receiver, it inserts a device between the source and the receiver to make the sound wave propagation have a significant additional attenuation, so as to reduce the influence of noise in a certain area where the receiver is located. The noise barrier isolates the noise source from the specific external environment affected by the noise so as to achieve the purpose of noise reduction. The noise reduction effect depends on the sound insulation amount of the barrier wall and the sound absorption amount of the enclosure. Main characteristics of sound barrier: easy to install and disassemble, beautiful appearance, with good sound absorption, sound insulation effect, fire, rain, moisture, rust, durable.

2, use

The sound barrier is mainly used for the sound insulation and noise reduction in expressway, elevated composite road, urban light rail subway and other municipal facilities, to control the influence of traffic noise on nearby urban areas, and also for the noise insulation and noise reduction of factories and other noise sources.
