In addition to installing sound-proof doors and windows and using sound-proof materials, you can also choose to carry out some small operations in small places such as furniture and decorations, which can also achieve the effect of eliminating noise.

The walls should not be too smooth. If the wall is too smooth, the sound will echo when it touches the smooth wall, thus increasing the volume of the noise. So you can choose decorative materials such as wallpaper with good sound absorption effect. In addition, decorative materials such as cultural stones can be used to make the wall rough, so that sound waves can be refracted many times, thus reducing noise.

Wooden furniture uses wooden furniture to absorb noise. Wood furniture has the characteristics of porous fibers, which can absorb noise. Meanwhile, you should also buy more furniture. Too little furniture will make the sound resonate indoors and increase the noise.

Fabric decorative fabric also has a good sound absorption effect. 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.
