What are the sound insulation methods for walls?
Sound insulation treatment method of wall (1) At present, some houses use light hollow bricks as external walls, and the sealing performance is poor. If car noise has a great influence on them, you can also add a layer of gypsum board to the wall near the road, fill the gap between the wall and gypsum board with sound-absorbing cotton, and then paste wallpaper or paint the wall on the gypsum board. (2) Thickening the wall: the street side should be soundproof, and the window on the street side should be converted into soundproof windows, such as double-layer windows, which can effectively soundproof. The insulating glass is selected, and the sound insulation effect is also good.

Therefore, you can choose decorative materials with good sound absorption effect such as wallpaper, and you can also use decorative materials such as cultural stones to make the wall rough, which can reduce noise. In addition, the walls and ceilings can be made of sound insulation materials, such as sound insulation cotton.
