1.    Door and window sound insulation

We know that the general sound insulation effect of doors and windows is not good. We often hear the sound coming in from outside, and the low-frequency sound spreads far away, and the interference effect is more significant. So what should we do? The window can be made into double glazing, that is, a layer is added to the existing window. Of course, the window should have a good sealing property, which is the least costly and effective method. For the sound insulation treatment of the door, a hollow double-layered door with a cavity can be adopted, the panel is made of plywood, and the sound-absorbing cotton is laid in the middle. If the door panel is a multi-layer composite sandwich door, the door seam should be made into a slanted opening, plus a blanket or rubber strip seal, so that it has a certain effect!

2.    Sound insulation treatment of the wall

The first method is to remove the original wallboard, add gray cardboard on both sides, and stuff it with polyester fiber sound absorbing cotton. This kind of scheme will have a good effect. The second method is to retain the original partition wall, and add a few columns to form a sound insulation wall with ester fiber sound absorbing cotton inside. If you want to be simple, evenly apply a layer of cement to both sides of the brick wall you have built. The gaps and holes in the leaking sound also have an effect on the sound insulation of the room, especially for the sound insulation of the intermediate frequency part, which must be sealed. In the case of a lightweight wall, a low-density gypsum board or a cement fiber pressure plate can be added to the inside.
