General home theater decoration sound insulation, sound absorption construction method

With the continuous improvement of people's living standards, more and more people are beginning to pursue high-quality life. Like the karaoke equipment and projection equipment that are far away from the past, the karaoke equipment and projection equipment began to enter the ordinary people's homes. People will inevitably have noise disturbances while enjoying the fun of life. In response to this problem that many people have headaches, the following will introduce the decoration and sound-absorbing and sound-absorbing construction methods of the Family Film and Television Hall. The design and construction can greatly reduce the spread of noise. The acoustic design of the family video hall is divided into two parts:
First, sound insulation design
1. Wall sound insulation Firstly, make a layer of keel in the wall part, leave a cavity of â‰¥50mm in the middle, and then fill the cavity with sound-absorbing cotton. (The sound-absorbing cotton here is not rock wool or glass wool, everyone knows the above two A kind of sound-absorbing cotton is harmful to the body. Sound-absorbing cotton should choose environmentally-friendly sound-absorbing cotton made of polyester fiber. Then use a double-layer gypsum board as a layer of lightweight wallboard outside the keel and place the sound-damping damping material between the two layers of gypsum board (note: all butt joints of the gypsum board should be sealed with putty or sealant).
2. The construction method of the ceiling sound insulation ceiling sound insulation is the same as the wall construction. If there is a suspended sound equipment in the ceiling part, it is necessary to install a shock absorber at the connection between the boom and the floor to prevent the sound of the low frequency vibration from spreading upstairs through the boom. .
3, the ground sound insulation (can do it according to their own situation)
For sound insulation on the ground, use sound-insulating cushions on the floor, cover the sound-insulating mats and cover them with 40mm thick cement. Finally, install decorative materials such as floor or ceramic tile on the floor. If you don't want to spend too much money, you can lay carpet directly on the floor. .
Second, the sound-absorbing design Because the requirements for sound when watching movies or singing karaoke will be relatively high, it is also necessary to absorb the sound of the wall part. At this time, some people may ask, is it not already soundproof? Here I want to talk about the difference between sound insulation and sound absorption. Sound insulation is to isolate, cut off or separate the sound. The sound absorption is to convert a part of the sound energy of the surface of the incoming material into heat energy loss, reducing the reflection of the sound, thereby improving the clarity of the sound. Therefore, in order to achieve the best appreciation effect, the sound absorption treatment is also a crucial link. The surface acoustic absorption is now generally selected as a polyester fiber sound absorbing panel. This material has good sound absorption effect, good color, environmental protection and simple construction.
The above is the decoration and soundproofing and sound-absorbing construction methods of the Family Film and Television Hall. I hope that I can help my friends who need to do the film and television hall to avoid unnecessary waste caused by noise disturbance to the neighbors or wrong decoration.
