Nightclubs are places of entertainment that young people often go to. When you open the door and enter the nightclub, it will be accompanied by the noise that focuses on music. The noise will be much less when the door is closed. How does this sound insulation effect work? The following editor will show you the secret of sound insulation in nightclub decoration

nightclubs are places of entertainment that young people often go to. When you open the door and enter the nightclub, there is a noise that focuses on music. The noise will be much less when the door is closed. How does this sound insulation effect work? The following editor will show you the secret of sound insulation in nightclub decoration

let you uncover the mystery of sound insulation in nightclub decoration

1. The best way to deal with noise is to first solve the problem of window leakage. To achieve the tight sealing of each window, whether you are a single-layer window or a double-layer window, sealing is the most important. The sound insulation system of the whole room is like the carrying capacity of a barrel, which is determined by the shortest piece of wood, and the sound insulation effect of the room is determined by the weakest window

2. The window sealing of entertainment places such as Diba bar KTV has been solved. The next step is to strengthen the sound insulation of the door. The sound insulation of the door does not mean that it is thickened, but depends on the sealing performance. Therefore, it is better to use professional fire-proof, soft wrapped sound insulation doors or steel fire-proof sound insulation doors with sound insulation performance grade above level 3 and R value above 30dB (a), which can prevent the sound source from spreading from the door and control the noise in the house

3. Improve the sound absorption and sound insulation performance of the wall. At present, most entertainment places such as disco bars and KTVs use light bricks (hollow bricks) as the outer wall, a wooden square (light steel) plus paper faced gypsum board, and then use decorative surfaces such as wallpaper (of course, the surface can also be treated with ordinary wall paint). This structure is too simple. From the perspective of sound insulation, the sound insulation performance of this structure can not be improved much. However, a large number of practical engineering experience shows that if a 20MM-35MM thick plant fiber sound-absorbing layer is sprayed in the cavity first, the single value evaluation r value of the sound insulation effect can be increased by more than 10dB, which is better than the inner filled sound-absorbing (insulating) cotton in terms of sound insulation and environmental protection, When the gypsum board is replaced with professional magnesite low-frequency sound insulation board, magnesite honeycomb sound insulation board and other materials, the sound insulation capacity and NR curve are significantly improved, and the weighted sound insulation capacity of the wall can be increased by more than 40dB (a)

4. In addition, entertainment places such as Diba bar KTV can also consume part of the sound energy by using thick curtains, which is also a relatively simple method. Carpets, fabrics and even sound absorbing (isolating) cotton can also reduce the impact of some reflected sound on the interior

5. Of course, no matter how you do sound insulation, you can't forget ventilation. A too closed environment is not healthy for human body. Noise prevention treatment should be designed on the side facing noise

6. Due to the vibration characteristics of KTV sound, the use of damping materials, such as damping and sound insulation felt, damping glue, shock absorber and other materials, should be considered in the sound absorption and sound insulation design scheme, which can reduce the resonance coincidence effect between the wall and the decoration plate, so as to improve the sound insulation performance

the above practices are aimed at dealing with the noise of entertainment places such as Diba bar KTV. We mainly mentioned several new types of sound insulation and sound-absorbing materials, namely, plant fiber sound-absorbing layer, magnesite low-frequency damping sound-insulating board, magnesite honeycomb sound-insulating board, damping sound-insulating felt, vibration damping glue, shock absorber and other professional acoustic materials, which can be selected by everyone, and are also effective for other noises

editor's summary: I'll introduce the mystery of sound insulation in nightclub decoration. I hope it can help you. More decoration information is available. Please look forward to it
