The first step is to analyze the source of noise. Before using the sound insulation method, carefully analyze where the sound will run. Admittedly, we must do something about the walls and floors, but don't forget the windows and doors of the room, which are absolutely thin parts. Sound leaks from these places, and the overall sound insulation characteristics of the room cannot be very high. If there is a sound foreign exchange, the first thing to pay attention to is doors and windows. In addition to installing sound-proof doors and windows and applying sound insulation, you can also choose to carry out some small operations in small places such as furniture and ornaments, which can also achieve the effect of eliminating noise.

The second step, the application of professional, such as polyester fiber sound-absorbing cotton, single layer 1.5 mm thick, reaching 26db. This sound insulation material has excellent broadband sound insulation characteristics and high damping, and can effectively block all kinds of air transmission. In the wall decoration, it is best to make the wall a little concave and convex, such as using wallpaper, wall covering and other materials for decoration, and their noise reduction effects are excellent.

The walls should not be too smooth. If the wall is too lubricated, the sound will be tactile. The sound-absorbing board has good impact resistance, good independence and high cost performance, and there are many colors to choose from. When the wall is lubricated, it will echo, thus increasing the volume of noise. So you can choose decorative materials such as wallpaper with good sound absorption effect. In addition, decorative materials such as civilized stone can be used to make the wall name rough, so that the sound waves can be refracted repeatedly, thus reducing the noise.

Put more wooden furniture at home. Wooden home has the characteristics of porous fiber, which can receive noise and has good sound absorption effect. The number of wooden furniture should not be too small, too little will make the sound hover indoors and increase the noise.

The sound absorption effect of fabric decoration is also good. The sound absorption effect of hanging fabrics is the same as that of flat fabrics, such as curtains and carpets, in which the sound insulation effect of curtains is the most obvious. It can not only absorb sound, but also has a good decorative effect, which is a good choice.
