[Home Theater Network HDAV.com.cn] Take a big screen, put two big speakers, and dare to say that it is a home theater? Do you dare to say that there is a video room at home? Obviously not, even if you use high-end The device is also at most an enthusiast. Really local tyrants, in addition to pursuing high-end equipment, dare to face every detail of perfect audio and video effects, from room selection to decoration, from wiring to equipment to perfection, in order to achieve the best results. It is no exaggeration to say that building a private audio-visual room is very particular.
Start with room selection
Best choice: basement
The problem is: living room, irregular room, a large number of rooms with floor to ceiling glass and doors and windows
Remedy: curtains, reinforced glass
Many people use the living room to be the audio-visual room. This is definitely a silky mind. In fact, the living room is really not a good choice for the audio-visual room. The semi-open structure of the living room, the acoustic structure is unreasonable, and the lighting is too good. Who can bear the bright and swaying place to watch the film? In addition, the large living room windows and glass are easy. Causes resonance and acoustic mirror diffusion. In addition, things in the room may resonate to produce noise, which will destroy the acoustic structure of the studio. Therefore, using the living room to play video and audio, it is just some helpless behavior of silk reeling.
In fact, as a personal audio-visual room, the first necessary condition is to have a separate private room. I recommend using the basement because I live in a separate basement, so it is convenient to use it directly to create a private video room. Do not worry too much about using the basement to play the contrast chamber. The windows, glass, and resonance are not considered. The only headache is to prevent moisture. The moisture in the basement is often fatal to the equipment. This should be noted.
Closed, no lighting, and sound insulation is important for the studio
If there is no basement, you can only play in a single room. When a single room is a personal audio-visual room, it is better to have a larger area, more than 20 square meters. It is best to choose a room with a more regular shape and a rectangular shape with an aspect ratio of no more than 2:1. It is more troublesome to use the normal room to play the contrast chamber, especially the room with sharp corners is the most helpless, and the sound is easy to produce irregular reflection, which affects the positioning of the sound. For rooms with more doors and windows, it is not suitable as a video room. The glass is easy to resonate and it is easy to reflect the audio. If you live in a building, the glass is prone to leaking sound. If you look at the film late at night, you will be attracted by your family. Or the neighbor's skunk.
However, if you have limited conditions, you can only use a single room in an ordinary house to be a video room, so it is best to prepare some remedies. Here are some simple suggestions. In this harsh environment, in addition to using reinforced glass, installing double-layer aluminum alloy windows for windows can also reduce glass resonance and leakage. In addition, the curtains are an excellent solution. But it is best to have a thick, rough surface, using wool and cotton curtains, so that the curtains can play a good sound absorption effect, reducing the effect of glass resonance and glass on the sound.
Wiring considerations need to be comprehensive
Best choice: brand quality line
The problem is: the wire shrinks and the layout is unreasonable.
Remedy: check before installation, audio and video cables are installed separately
Renovation may be the most overlooked problem in the audio-visual room
For the audio-visual room, the wiring is more complicated, after all, the speaker cable, the audio signal cable, the video cable, and the like should be considered. Moreover, for individuals, there is absolutely no way to accept the exposed wires and the presence of bright lines. The audio-visual room needs to fully consider the wiring problem. However, at this time, it is not necessary for the individual to go to the company, and the decoration plan can find a professional company. However, for the design and materials, they are all checked by themselves. What are the wires are bought by themselves? This is because I am worried that if the quality of the things purchased by the decoration company is wrong, the consequences will be serious.

First of all, it is necessary to pay attention to the quality of the wire. Nowadays, many wires are shrinking seriously. What HDMI cable and microphone shielding wire are shrunk, the speaker cable looks very thick, but the core wire is very thin and so on. Therefore, to buy the brand wire, the wire of the skin is opened to see if the core wire is strong, and it is necessary to have a complete shielding layer.
　　 Pay attention to the wire must choose high quality, not bad money
The second is wiring. For private audio and video rooms, the investment is already big enough, so don't save money on the wiring. All audio and video cables must be taken separately and separated from the power cable as much as possible to avoid interference from the power cable to the audio and video cables. Of course, I can't hear the impact of different power types on sound quality...
Acoustic transformation is very important
Best choice: enhance sound absorption, pay attention to the overall layout
The problem is: too much furniture, no sound absorption
Remedy: the furniture has no door design, the light is set at the back of the seat
Let's talk about the effect now. The private audio-visual room is actually enjoying the best audio and video effects, so the sound field structure is very important. Many of my friends with enthusiasts are willing to spend a lot of money on this. The reason is actually very simple. In the audio-visual room, there is a higher sound pressure and a wider frequency response. If the acoustic structure of the room is unreasonable, then the diffraction of the sound wave, the reflection of the sound, etc., will greatly affect the sound quality. Many people only know how to spend money on equipment. In fact, it is just a display, and spending money in a place that can reflect the actual effect, then it is worth the money.
As a local tyrant, you must use sound-absorbing cotton.
The location of the space, light source, and sound must be correct
Many professional veterans like to lay sound-absorbing cotton in the audio-visual room. The function of sound-absorbing cotton is to absorb sound, so that it is not easy to produce reflection sound in the listening room, which makes the sound cleaner and also helps the sound to be positioned. Of course, the design of acoustic diffusion and sound absorption is still very complicated and needs to be analyzed and designed according to actual conditions. If you don’t play, you should pay for professionals. Here again reflects the importance of the basement to do the audio-visual room. If there is an ordinary room, who has so much space to engage in sound-absorbing cotton?
When you have the audio, you have to talk about the video. Here, you should pay attention to the design of the audio-visual room. First of all, on the background wall, do not use the background wall with strange shapes and too bright colors. This can easily interfere with the attention when watching a video. Secondly, it is the setting of the light. This mainly refers to the setting of the long light when viewing. The best way is to put it behind the user, which can reduce the impact of the light on the video. If you are not sure, you can try the location of the light, basically close to the cinema, the effect is almost the same.
In addition, the private audio-visual room should not be too much meaningless, so as not to affect the acoustic structure of the room. The audio-visual room should be based on simplicity, in addition to the necessary equipment, seats, equipment cabinets, to minimize the existence of other homes. For furniture in the studio, such as seats, it is best to choose a flexible material such as a leather or cloth sofa. For equipment cabinets, film cabinets and other furniture, it is best to use no door design, which can also minimize the resonance caused by the cabinet door is not strong.
"壕" world, top equipment together
If you are not exaggerating, the owner who can play the private video room himself is not very bad. Many newcomers do not know how to buy equipment, only choose the most expensive, not the best, but the final effect is not necessarily cattle. Maybe we buy equipment that does not take into account the price factor, but definitely consider the actual effect and the match between the equipment.
