1.Room selection

It is understandable first that you have to make room for the installation of the audio-visual room if you want to establish a home theater. A good audio-visual room requires a room that is biased towards a rectangle. Almost good home theater layout is basically rectangular, because sound surround effect is the best in this case. Secondly, contrary to what many people think, the area of the studio should be as large as possible. As a result, the sound will not be confused. Finally on the speaker placement, it must be placed symmetrically left and right, and the distance cannot be less than 2 meters, then the auditory experience is the best.

2.Resonance problem of doors and windows

In terms of physics, sound is vibrated. The sound of the home theater is not weak, the average sound pressure level is about 90 decibels, and up to 120 decibels. That is to say, if the doors and windows are loose, once the video room is broadcast to the big scene, the glass windows on the walls will squeak. It will not only make us worried, and also undoubtedly affected the viewer's audiovisual experience. Resonance is inevitable, but what you have to do is try to lower it. You can fill the sandwich with cotton, and change the glass of the door and window into a double structure if conditions permit.

3.Material selection 

Many people ignore the use of soundproofing materials during the installation process. Therefore, the sound penetration is very serious during the use of the audio-visual room, which often affects the rest of family or neighbors. Therefore, the sound insulation material for the wall and floor must be used.

4. The impact of circuit problems on sound

Many people can not solve a mystery in the process of use in the home theater, that is the noise is serious. Many people blame the source of the problem on the speaker, but it is not. Home theater is a high-power consumption project, the burden is still very large for the circuit of ordinary households. Therefore, speakers, lighting and TV screens are best avoided to connected together, use separate wiring for the respective equipment. If the condition allows, you can install a dedicated line for the speaker, get rid of the reliance on multi-function sockets. Then it can avoid causing noise and affecting the hearing experience.

In addition to the above four points, home theaters need to pay more attention to wiring, lighting, equipment, etc. It is best to find a professional audio-visual room decoration person for guidance.
