[Home Theater Network HDAV.com.cn] KTV sound insulation wall practice on the issue of sound insulation ceiling. Soundproof ceiling is also called suspension. Because the noise can spread upstairs, and because of the noise of the penetration of the sound. So use sound absorbing materials. This is basically sound absorption rather than sound insulation. So the only way is to do the suspension. If the bar is not on the ground floor, then the soundproofing measures should be made on the ground. The ground soundproofing method is to use a thin sound-absorbing panel. The ground floor can be made of inorganic spray, and the surface can use tiles or floors. Remember to use inorganic fiber spray to cover the sound insulation board, sound insulation wall and soundproof floor surface to enhance the sound insulation effect.

What materials should be best for soundproof walls?
The economical and practical first choice is 2/4 red brick wall and cement wall on both sides. This partition wall must be built to the top. If you need to go through the ventilation duct or other wiring, you should punch the hole. You should pay attention to the sealing problem of the pipeline. Otherwise, crosstalk can also occur. Followed by sound insulation wall panels, this material is a professional sound insulation material, on both sides is a foamed plastic with sound insulation in the middle of the metal sheet, the greater the thickness of this wall board, the better the sound insulation effect. In some places, due to the weight problem, brick walls or other wall-building methods cannot be used. Only light steel keel gypsum board can be used. Our suggestion is to add a layer of harder cement board to the outside of the gypsum board. This cement board has the same appearance as the gypsum board (the size is similar), but the hardness is much higher than that of the gypsum board. It is a good sound insulation material. It should be noted that the construction process is problematic, especially the part of the gap must be sealed.

Ktv soundproof wall installation method:
1. The original wall is cleaned and installed with wooden keels. The distance between the keels is about 600mm. (The inner side of the keel is covered with a layer of soundproof felt to avoid rigid connection.)
2 The keel void is filled with environmentally friendly fiber sound absorbing cotton.
3. Put on the soundproof felt and seal it with a layer of damped fireproof soundproof board. (The soundproof felt and the soundproof board are first combined with the universal glue. The soundproof felt is made longer than the soundproof board for lap joint.) Fix the keel with a self-tapping screw with a damped baffle composite.

The sound insulation effect is checked by normal music in a room, and the attenuation of the sound is measured one meter at the door. For example, the sound pressure level in the room is 90 dB, and the sound pressure level measured at one meter outside the room is 60 dB. Indicates that the sound is 30 dB.
