The acoustic principle of the sound insulation wall is to leave a cavity or buffer layer between the original wall and the sound insulation wall, so that the noise can penetrate the space and reduce the distance, and then the noise is converted into heat energy through the micropores in the sound absorption material, which can further reduce the noise, thus playing the role of heat preservation while doing sound insulation.

Sound insulation wall structure:

The thickness of the sound insulation wall is determined by the size of the noise source. The greater the noise source, the thickness of the sound insulation wall will increase appropriately, generally around 5- 10 cm. Adding a soundproof wall will definitely sacrifice some indoor area. The structure of sound insulation wall is generally to leave a cavity of 2-5 cm between the original wall and the light steel keel frame, fill the light steel keel frame with sound insulation material, then cover it with a layer of damping sound insulation board, and finally add a layer of damping sound insulation board.
