How to realize the sound insulation of ktv rooms in hotels

When the floor and other building components are hit, the vibration will spread in the components and their connecting structures, and finally the sound will radiate into the room in the walls and ceilings, and all the solid connecting components will vibrate. If solid objects are separated or elastic damping pads exist between components, the propagation of vibration will be greatly hindered at these positions. When spring or glass wool with similar spring effect is used as a cushion to make the ground "float", the impact sound insulation ability of the floor can be improved. The vibration isolation floor and the supporting elastic cushion below form an elastic system. The general law of vibration isolation is that the heavier the floor, the better the buffer, the greater the settlement and the better the vibration isolation effect.

2. Elastic soundproof ceiling

The subwoofer in the bar will also spread upward through smallpox. If the upstairs is a residential building, then a sound-proof ceiling must be made, and a solid sealing material can be used to prevent noise from radiating out through the ceiling. However, it is not suitable to use very hard materials, and the gap between the ceiling and the surrounding wall should be properly sealed, and elastic connections, such as elastic hooks, should be adopted; If the ceiling is covered with porous sound-absorbing materials, the sound insulation effect will be improved.

3. Enhance the sound insulation characteristics of the wall.

In order to enhance the sound insulation characteristics of the wall, the general load-bearing wall adopts steel plate concrete or solid brick structure, which has good sound insulation effect. Most of the problems are caused by the lightweight hollow brick or chip board used in the partition wall, and the sound insulation characteristics are only -25dB~-30dB. Most KTV rooms have one or two walls with this structure. There are two concrete solutions. First, tear down the original wall, install poly-wool sound insulation boards on both sides, and fill in sound-absorbing cotton, which will have good results; The second is to keep the original wall, install wooden keel, stick sound insulation board, and form sound insulation wall with sound absorption cotton in the middle. This scheme adds a new wall, and its sound insulation characteristics are better than the previous scheme. However, it has the disadvantage of reducing the room width by several centimeters.

4. The room in the room

Room-in-a-room is a kind of building with the best sound insulation and vibration isolation effect, that is, another room is built in the room, the inner room is located on springs or other vibration reduction equipment, and the surrounding walls and ceilings have no connection with the outer room. The formation of an air layer between rooms is not only conducive to the sound insulation of air sound, but also conducive to isolating the sound generated by impact.
