A bar is a place where people can relax at night when business is booming. In the evening when people are already sleeping. And the bar is very carnival. High power subwoofer and other audio-visual equipment, people's loud noise and so on are all difficult problems to solve in the bar. In order not to disturb the residents' daily rest in the evening, we must solve the noise problem.            

The sound insulation treatment of the bar mainly includes the sound insulation treatment of the ceiling, the sound insulation and vibration reduction of the bar floor and the sound insulation treatment of the bar wall. The bar soundproof ceiling adopts elastic ceiling and has no rigid combination with the original structure to prevent sound impact from the original structure of the building to the upper room. The attenuation of sound insulation is 45dB, and the sound resonance frequency point is less than equal to 31Hz. The elastic insulation ceiling is as close to the ceiling as possible to ensure room height. The length of design hanger is 300mm. If possible, it can be shortened according to the construction site condition. The length of partial suspender (such as cross beam, ventilation pipe, water supply and drainage pipe, etc.) should be adjusted according to the actual height. The lower part of the finished surface of the elastic ceiling should be located above the fire sprinkler pipe and the air conditioning trough. The suspension of lighting, ventilation, air conditioning pipes and partially decorated precast parts must be isolated from the original floor with shock absorbers. In order to ensure sound insulation effect, the cable and fire pipes of sound proof ceiling should be sealed by sealant to prevent leakage. Don't open a large hole in the lighting. Air conditioning vent. It does not damage the sealing performance of sound proof ceilings, which is helpful to increase the volume. Sound insulation ceiling does not make styling and drop - level smallpox. Modeling ceilings can be used as common materials, larger lamps can be opened, and air conditioning outlets.
