Home theaters want to get good audio-visual effects. In addition to good equipment, you need to prepare a good space environment. The layout and decoration of the space directly affects the visual effect and also affects the audiovisual effect. The renovation of the space will greatly enhance the audio-visual effect of the theater. Today, let's take a look at the considerations for space decoration and layout when building a home theater.
The size of the space directly affects the audiovisual effect of the theater. Too small a theater will affect the user's experience, and both sound and visual effects will be limited. Nowadays, many users will choose the projector as a visual display device. The author believes that in order to ensure the user's comfort and visual sense, the space should be no less than 10 square meters. Conversely, the user does not need to filter the projection.
The author consults the relevant home theater information, most home theater design, the ideal audio-visual room should be rectangular, it is best not to choose a square or the size of one side is just twice the room on the other side. If the space is just a formal shape or a long corridor with a narrow side, it is best to modify it to achieve better audiovisual effects.
The space has been set. In the home theater, if you want to get good results in both viewing and listening, the decoration of the space will play a very important role. The cost ratio of such a home theater is basically the same as the equipment cost.
Home theater space processing
The processing of the home theater space directly improves the sound effect, and the most familiar theater sound insulation treatment. Including doors and windows, walls and a panel and ceiling, the appropriate decoration can improve the sound and visual effects in the theater. Generally speaking, the walls of the house are mostly brick walls except for the doors and windows. The hard walls are very strong for high, medium and low frequency reflections, and the sound will sound very harsh. Appropriate sound absorption can make the sound more charming. You can use the decoration materials with sound absorption effect.
Wall surface: Common sound absorbing materials include mineral wool, glass wool, polyester sound absorbing cotton, etc., which can be made into a soft bag form during decoration. Of course, it is not necessary to make the entire wall surface sound absorbing material, only about the speaker and listening position. It can be decorated in the middle, and it can be used as a decoration for the wall.
Floor: The home environment, the floor is mostly tile or wooden floor, but in the acoustic angle, the hard ground has a strong reflection on the sound, which not only destroys the sound image localization, but also easily generates standing wave interference. Therefore, it is necessary to lay a thick carpet to play the sound absorption function.
Audio and video equipment placement
After the position of the demo screen is determined, the projector and the screen are hoisted, and the position of the speaker is also determined. 5.1-channel speakers, in which the front speakers are placed on both sides of the projection screen, and have a circular arc position with the center or surround speakers. Their horizontal placement height is preferably 30 cm above and below the center speaker in the center axis of the tweeter in the main speaker.
The surround speakers are mainly used to create the diffusivity and breadth of the sound field, so it is preferable to place it at a position 50 cm higher than the head position when the viewer sits down. The center speaker is usually placed in the lower middle of the projection screen.
The rear speakers are generally placed behind the viewing seats, and need to be reserved a certain distance from the wall corners to increase the depth of the sound field. If the wall is installed, a dedicated hanger can be used to reduce the contact surface between the cabinet and the wall. Of course, the effect of the sound effect, in addition to the location of the device, can also be adjusted through professional tuning to improve the sound effect that the user hears.
Wiring details
Pre-embedded line: Wiring is the most cumbersome work in home theater construction, but it also needs the most attention. The new house has just come down and has not been renovated. It can be pre-wired in case it is known to build a home theater. This situation is pre-embedded, users need to carefully plan the equipment connection required in the theater, including audio cable, video cable, power cable. The layout of the embedded line does not affect the aesthetics of the overall scheme, but there are also certain defects. The line is not long enough, the position is deviated, etc., which will make the embedded line useless.
Suggestion: When purchasing the wire, try to do enough filtering, and do not shorten it, and reduce the estimation error caused by wiring.
Open line: After the position of the line is determined, the arrangement of the line needs to purchase an appropriate slot. For the overall effect of the space, the corner of the corner is generally used as the position of the line.
When wiring, since the power supply magnetic field will interfere with video and audio signals, it is necessary to avoid the power cable sharing a single slot with other wires. If it must be put together, it is best to install a shield and separate the power cord from other wires as far as possible.
The layout of indoor furniture should be convenient to use and the appearance of the room is beautiful, and the overall color of the theater is mainly dark color, while avoiding the use of reflective materials, it can effectively reduce the reflection of light during the projection, and avoid affecting the projection quality. . At the same time, the necessary cinema auxiliary equipment can bring a better experience to the user, such as home theater seats and auxiliary lighting, which can increase the atmosphere of the theater and make the user experience more comfortable.
