1. Sound insulation treatment plan for the bar wall:

First, stick a layer of vibration-absorbing pad and sound insulation felt on the original wall, add light steel keel, and fill the keel cavity. Layer sound insulation cotton, and then seal the wooden pegs to dampen the sound insulation board. After that, polyester fiber sound-absorbing panels are used as exterior decoration to achieve the effect of external sound insulation and internal sound absorption.

2. Bar ceiling sound insulation decoration plan:

Firstly, install a shock absorber on the ceiling floor. The hanging bars should use shock-absorbing hooks for shock-absorbing treatment, and add light steel keels. The keel cavity is filled with a layer of sound insulation cotton, and then the composite damping sound insulation board is installed. Then lay a layer of soundproofing cotton. Finally, a layer of composite damping sound insulation panels is installed to ensure sound insulation.

3. Bar floor sound insulation and vibration reduction decoration plan:

1. Level the original floor first, and seal the holes tightly;

2. On the original floor Lay floor shock-absorbing pads. When laying the vibration-absorbing pad, the ground should be cleaned to avoid damage to the sound insulation material caused by debris on the ground, and the edges should be trimmed in advance;

3. Lay the sound-insulating felt above the vibration-absorbing pad;

4. Then lay a layer of 30mm vibration-absorbing board;

5. Pour a 50mm thick concrete layer on top and add reinforcement inside;

6. Surface layer Just level it.
