When many friends are building their own theaters, the first thing to consider is the noise nuisance problem (what? You didn't think about it? You are reading this article that you may have been looked for by a neighbor...), the home theater audio-visual room decoration is in the home environment. The creation of a cinema-like viewing space, from the choice of space, the processing of the sound environment, the configuration of the equipment to the determination of the overall decoration style, are important factors to consider in the process of acoustic environment decoration design.
In the process of home theater decoration, it is necessary to consider the treatment of the acoustic environment. The first thing to do is to do sound insulation and sound absorption. For the treatment of sound insulation, because of the difference between the audio-visual space environment and the sound reproduction effect, there are many sound insulation measures. Before taking sound insulation measures, carefully analyze where the sound will come in and out, and take measures against the wall and the ground, but not Forgot the windows and doors of the room, they are relatively weak parts. Here are some of the main three solutions.
1. Improve the sound insulation of windows and doors
As a countermeasure against sound insulation of a window, a structure of a double-layered window is usually used. It is possible to keep the existing windows and add a window to acoustically handle the windows. It is also a good choice to create invisible windows, while also paying attention to the gaps in the windows.
The door is a relatively weak link for sound insulation. The ordinary door does not meet the sound insulation requirements of the home theater, and there will be door seams. The professionally-designed soundproof door is the choice of home theater. The soundproof door customized according to the acoustic requirements of the audio-visual environment can not only meet the sound insulation requirements of the audio-visual space, but also handle the door seams very professionally, which can ensure the tightness of the door.
2, the sound insulation performance of the wall
The load-bearing wall of the general residential building is made of steel plate concrete or solid brick, which has better sound insulation effect, and the partition wall is the focus of sound insulation treatment. The partition wall is mostly made of light hollow brick or gray cardboard, which has low sound insulation performance. Most home theater rooms have one or two walls. Therefore, the partition wall is a serious place where sound leakage occurs, and the air vibration in the middle of the hollow brick causes the wall to resonate. To solve this problem, you can choose to remove the original wall, rebuild a soundproof wall, or retain the original wall and add a soundproof wall.
3. Create an audiovisual space for the "room in the room" structure
Creating the audio-visual space of the "room in the room" structure is the most important sound insulation means for professional home theater decoration design. The "room in the room" is to soundproof the four walls, the ceiling and the ground in the room. The final result is to create a room in the original room. In order to completely isolate the inner and outer walls and not transmit any sound vibration, it is necessary to use the isolation device in the structure of the "room in the room", the construction is complicated, and the manufacturing cost is much higher than any of the previous modification methods.
The ultimate goal of home theater decoration and sound insulation is to have the home theater meet the standards that it recognizes, take appropriate measures according to local conditions, and obtain the sound insulation effect equivalent to its own economic ability and appreciation level, while at the same time not disturbing the lives of others, harmonious coexistence It is the most important thing.
