[Home Theater Network HDAV.com.cn] private cinema design three steps, the first step pipeline port pre-buried; the second step of acoustic processing is the key; the third step visual effects increase the mood; the walls of the audio-visual room generally follow the "front wall The principle of hard, left and right side wall sound absorption, and rear wall diffusion is to be renovated; the ceiling is best to have both sound absorption and diffusion functions. The basic requirement for handling doors and windows is to have certain sound insulation and sound absorption functions, you can increase the weight of the door and The thickness is best done with a professional soundproof door. First step pipeline port pre-buried The audio-visual room has higher requirements on the power supply. It is best to take a few wires directly from the incoming line. The upper line in the power supply box of the audio-visual room should be separated from the outgoing line, and separated by the distance of each current and rectangular, and fixed by the line card. There are also a few points to be reminded: If your audio-visual room is to be equipped with a central air conditioner and a wireless remote control lighting system is installed on the wall, you should consider it in advance when planning. In order to make the audio-visual room neat and tidy, it is convenient to install and operate in the future. It is necessary to pre-bury the pipeline and port on the six-sided wall during the decoration. When the line is pre-buried, the special signal line should be wrapped with PVC pipe and separated from the lines of the air conditioner, refrigerator and telephone, and the wires should be routed separately to avoid mutual influence. The quality of various wires should be better to meet the long-term use, so as to avoid the wall or floor being smashed in the future due to wire quality problems. The second step of acoustic processing is the key The walls of the audio-visual room are generally decorated in accordance with the principle of “hard front wall, right and left side wall sound absorption, and rear wall diffusionâ€. The left and right side walls must be sound-absorbed to ensure clear sound and pure sound. Some 1m to 1.5m wide and 2m high terry cloth or wool blanket can be placed on the side wall between the speaker and the listening position; To be hard, you can save a certain low frequency, so that the low frequency can extend forward better; the corner is the strongest place for standing waves, and the special objects such as bookshelf and CD rack can help the sound. The back wall of the listening position can be treated as sound absorption and diffusion. However, it is recommended that the seat is preferably 0.6m or more from the rear wall, and the sound absorbing material is adhered to the diffusion plate, so that the sound can be absorbed and diffused. The floor of the living room is mostly marble, tile or wooden floor. The tiled stone floor is easier to clean, but it is also easy to cause high-frequency piercing. You can improve it by laying a thick carpet about 2m~3.2m on the floor. Although the wooden floor is very suitable for the audio-visual room, if the wooden floor is directly paved It is too wasteful on the concrete floor, and its sound effect is similar to that of the tile floor; if the wooden floor is nailed into a cavity, it will have a good absorption capacity below 100 Hz, and the low frequency effect of the sound will be very good. If you can put pebbles under the floor, you can just fill the gap that is easy to cause standing waves and resonance, and even the drawbacks of the cavity wood floor can be overcome. The ceiling is best to combine sound absorption and diffusion. We recommend three methods of ceiling: one is light steel frame plus mineral fiber board, which is effective for resisting excessive indoor reverberation, but has no diffusion function; the second is to use small arc The panel is affixed with PVC paper on the downward side of the curved piece, and the concave side is glued with sound absorbing cotton. This design not only has the function of absorbing and diffusing, but also does not form a cavity for absorbing low and medium frequencies; The design of the small arc panel and the outer stretcher is both beautiful and practical. There are also enthusiasts who are covered with sound-absorbing cotton on the ceiling of the ceiling and fixed with wooden strips. The pipeline can pass through the ceiling. The basic requirement for handling doors and windows is to have a certain sound insulation and sound absorption function, you can increase the weight and thickness of the door, and you can also fill the sound absorption material in the middle of the double door. Similarly, the windows of the audio-visual room can be transformed into two or even three-story glass windows, and the glass and the frame are connected by rubber strips. In the door seams and window joints, the sealing strip can be said to be the easiest way to sound insulation. The third step is visual effect In addition to listening to the sound effects, home theaters must also consider visual effects. For ease of operation, ceiling lights can be installed in the appropriate position in the listening room instead of fluorescent lamps, as the latter's ballast hum can cause noise interference in the listening environment. The theater should be fitted with dark, heavy curtains or shaded blinds to enhance the contrast of the video. In addition, you can also consider the beautification of the audio-visual room environment, such as hanging a thick curtain behind the speaker, in addition to sound absorption will also give people a sense of the stage, but also some music content related Art or musical instruments will give people a lot of thoughts and increase the artistic atmosphere. At the same time, proper arrangement of some evergreen foliage plants can make people feel comfortable.
