The noise downstairs in Changsha is too loud. How to make sound insulation and sound absorption on the floor at home?

On-site construction steps of family sound insulation decoration:

Material: C20 fine stone concrete +5MM shock absorber +5MM shock absorber +3MM soundproof felt+steel wire mesh+adhesive tape.

1. Site survey of rough houses.

2. Dismantle the wall and the insulation layer.

3. Water and electricity building and window sealing installation.

4. Leveling the ground for the first time just covers the water and electricity pipelines.

5. Cushion laying. The two floors need to be staggered to avoid seams.

6. The cushion should be attached to the edge of the wall, exceeding the height of the leveling layer behind.

7. First, lay a soundproof felt on the ground and choose the scheme with the smallest splicing gap.

8. Seal all flat seams with high-viscosity adhesive tape.

9. The sound insulation felt exceeds the bottom of the doorway, and the bottom of the doorway returns to the wall, which is higher than the leveling layer. The sound insulation felt is relatively thin and will not affect the installation of the door.

10. laying barbed wire, which is commonly used in Changsha family decoration, chooses the kind with hard steel wire.

1 1. The cut steel wire needs to be bent to avoid puncturing the shock absorber. The sound insulation felt is strong and not afraid of puncture.

12. Laying heating pipes directly above the sound insulation layer. The order should not be reversed, otherwise the heating pipe should be punched from the sound insulation layer before it can be mounted on the wall, which will affect the sealing performance of the sound insulation layer.

13. Bricklayer leveling. After drying, cut off the sound insulation felt on the back wall, and you can clearly see that the ground is separated from the original wall.

14. After the ground is completed as a whole, the sound insulation of the wall and ceiling shall be started.

Which is better, floating floor or soundproof ceiling?

Floating floor is an active scheme to solve the problem from the source of noise, and the sound insulation and shock absorption ceiling is a passive scheme. The sound insulation/damping/noise reduction effect of floating floor is better than that of damping ceiling, and the cost is lower. So it's best to communicate with the neighbors upstairs before renovation.
