The way to save money is to use benzene board and plaster to make partition walls. I don't know where you are in many places. This kind of practice can't pass the fire check! The high-grade soundproof wall is made of two layers of sound insulation panels inside and outside, and the wall is supported by "keel". The wall is hollow and the inner wall is soundproof cotton. However, there is a saying that "good sound insulation does not absorb sound, good sound absorption is not soundproof" if You want to do KTV. When you are soundproofing, you should also take into account the sound absorption effect. This requires professional people to make a practical inspection of your storefront to give a decoration plan!
First, we must control the sound transmission of the noise source. Do not hang the speaker directly on the wall or on the ground. You can use elastic hooks or vibration damping pads to make the speaker and building process elastically connected. The sound insulation of the ceiling must be done well. The keel is made on the ceiling, the sound absorption cotton is filled in the keel cavity, and the sound insulation material and plasterboard are underneath.
Second, when KTV and the house are separated by a wall, the sound insulation material must have good sound insulation performance, otherwise your neighbors may be guilty, the elderly, children, adults at work... I will not say anything, The consequences of poor long-term sleep can be very serious. The wall can be constructed in the same way as a suspended ceiling.
Third, if your home is KTV downstairs, it is difficult to ensure that the sound is not transmitted when the ground is soundproofed, because there are two ways to spread the noise, one is air propagation, and the other is object propagation, that is, building propagation. The upstairs residents want to do sound insulation, and then sound the ground and the wall to ensure that their room is quiet, but the sound will spread from the 2nd floor to the 3rd floor along the wall, other families will be affected as usual. . Therefore, the best way is to make soundproofing for KTV.
