[Home Theater Network HDAV.com.cn] Because I recently helped a few friends to do the program configuration, some made acoustic design, some are ordinary living room decoration, and then after seeing their furniture and decoration, they can only shake their heads and sigh. The purpose of this sticker is to give you some suggestions in the decoration. In addition, please don't ask me how to solve it. I can only ask the reason, but I can't mention the solution.
1: Power:
Many people know that they have to choose more than 4 flat wires to be laid separately for audio and video systems. But how many people know how many devices can be loaded on this independent line? How many people know how to separate lines for projection or TV? It is estimated that no one can answer clearly. The general audio-visual room actually needs 4 lines, 3 of which are independently pulled from the meter, and the other is to control other lights and other equipment. This can be ignored, a 4 level + is the air conditioner, I don't say much about this. The other 4 flat + is for power amplifier and gun. This one can only connect 2 kinds of equipment, which is power amplifier and gun. If it is the front and rear level, the front stage can't connect. On this line, the other one that comes out separately is 2.5 flat lines. After this line is connected, you can put a filter on it, or when you decorate it, you can dig a hole in the filter next to the circuit and then put it into the filter. According to your actual needs, it can be separated from the filter. These two methods can be used. What is connected to this line? TV or projection, preamp, CD or DVD, just connect these devices. If you do the ultimate, you can project the TV. And the pre-CD is also divided into 2 lines, but generally 1 line, when the karaoke and AV system are installed in the same room, then the 4 flat + line should be replaced with 5 flat ~ 6 flat lines, then the karaoke amplifier is connected to this line, the wireless microphone is connected to the TV. On this line, the karaoke machine can be connected to the light bulb. There is also a misunderstanding that the socket is not enough to pull the tow board. This is actually very bad, so the design of the audio-visual room must be considered clearly. I have to install those equipment. I will add those devices in the future, the location is there, the wall is ready, don't use the tow board!
2: Ground:
Many newcomers will choose smooth tiles for their beauty. I don’t know if your voice reflection space is very problematic. Many people later helped me to solve the problem as long as the carpet is laid, but in fact, this only absorbs some of the standing waves. The bass is only there, there will still be reflections on the carpet. If this is not the case, it will be solved on the material selection at the beginning. It is not necessary to spend a lot of money to get all kinds of low-frequency traps, wool carpet tapestry, etc. Start to choose materials, please throw away the tiles directly (Would you want to install the matte tiles?) and choose solid wood flooring, and solid wood flooring can not choose the kind of piano paint, otherwise it is not too different from the tiles, decoration It is also a little tricky. When installing the floor, the workers will first lay a layer of keel to prevent the unevenness of the high ground. If it is directly on the board, then your ground is a whole block of resonance box, so please install the keel. Then lay a certain thickness of sound-absorbing cotton in the grid. If you are afraid of dragging the water and letting it go, you can put the fine yellow sand in the square.
3: Ceiling:
Many people have a halo cast ceiling on the 4th side after the ceiling. This is not recommended. The best acoustic room is vaulted. If you can't make a vault at home, don't hang a layer of gypsum board on the 4th side. The top of the ceiling is the same as the ground. Please do not have any gaps. Otherwise, a resonance box will be formed. You can fill the keel with sound-absorbing material and then lay a layer of blockboard and then ceiling. The panel will let the decoration master hit every 3CM~5CM. A small hole! Many other people project the HDMI cable surround line is the ceiling or the ground. When choosing the laying pipe, please choose a little larger according to the diameter of the wire. Then please ask the decoration master to make a small hole and then use Sponge or sound-absorbing cotton wrap the pipe!
4: Wall surface:
Many people choose plexiglass as a TV wall for aesthetics. This is really a problem. A good front wall can actually be spliced ​​with solid wood acoustic board + polyester board. It doesn't need a full wall. It only needs TV surrounds and can cover the speakers. Place it in the position. If you really don't want to do it, brush the lime water and paint it. It is also convenient to add the sound-absorbing or diffusing material after the filling. The left and right rear walls are also the same. Please choose the thick curtains for the position of the window. This way you can pull up when listening, to prevent window sounds or external sound interference!
5: Furniture:
Please choose the fabric, leather, do not get a solid wood sofa or metal material, this thing is just a decoration, not good for the sound, not comfortable, sit up is not comfortable, the coffee table can choose solid wood, tens Do not choose the hollow metal cylinder as the 4 feet or the top is the glass type, otherwise it is equal to a small resonance box, the TV cabinet is the same, please choose the open type, do not choose the sliding door or the sliding door type, otherwise the door One level is also a resonance. The specific style can refer to the audio cabinet on the TB. In a word, there can be no box that can be closed in the audio-visual room, so those on the TV cabinet should be short cabinets, and the wall should be thrown like a locker. Considered!
Basically these 5 points, in fact, there are still many can write, such as the choice of the material carpet, whether the low-frequency trap must be, the best layer height, etc., but the purpose of this post is only a preliminary misunderstanding And the simplest acoustic decoration that can be solved in the decoration period, I can estimate that I can write a book of no less than 5W words, I am not so empty, laugh ^o^, thank you!
