What if the neighbors upstairs hit the wall in the middle of the night?

There is no way to transmit solid sound to lower floors. If you don't want to affect the lower floor before decoration, then one is to lay an overhead floor and put a rubber pad under the grille. In addition, before tiling and leveling, rubber isolation felt should be laid in advance. Real estate developers are just trying to keep costs down in order to make money.

No matter whether the bed hits the floor or the wall, there is no good sound insulation measures. Similarly, the sound of walking barefoot and patting the ball belongs to low-frequency noise, which is the sound emitted by the vibration of the floor and walls of buildings. At present, most sound insulation methods have a good sound insulation effect on medium and high frequency noise, but there is basically nothing to do with this low frequency sound.

If you are worried that your voice will affect the downstairs, you can spread damping felt and sound insulation mat on the floor during the decoration, and then spread the floor, which can play a role in sound insulation. And if you want to isolate the sound upstairs, there is basically no good way at home.

If frequent noise affects the downstairs, it is best to remind the upstairs residents first, and most people should pay attention to convergence. If the communication fails, you can report it to the property or call the police. If this kind of voice doesn't appear several times a year, bear with it, it's not easy for everyone.
