Sound barriers 

Sound barriers 

are mainly used for sound insulation and noise reduction of roads, highways, elevated composite roads and other noise sources.

It is divided into reflective sound barriers for pure sound insulation, and composite sound barriers for 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.

Soundproofing 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.

Usage
Noise/Sound Barrier is usually used in Highways, High-speed railway, railway, villa, industry and so on. Highway Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources other than cessation of the source activity or use of source controls.
