What is the difference between sound barrier and soundproof wall?
Sound insulation wall is through the combination of different sound insulation materials and sound insulation structure, made of a wall to achieve the purpose of noise reduction.
Sound barrier is generally used for outdoor noise control engineering (such as construction sites, railways, highways), the general noise source range is large, can not be completely closed;
Sound insulation wall is generally used for indoor noise processing, the noise source can be completely closed up.
Sound barrier is in the sound source and the interference between the area set up a barrier, making the noise has a certain attenuation.
