【 Weak current College 】 home theater setup

Household audiovisual Centre should have performance good acoustic effect and a decorative appearance and atmosphere of a warm living room. For this reason put forward several decoration.

1, door and window handles
The purpose of dealing with Windows and doors are sound, sound absorption and dust. A lot of noise is through the door, window into the rooms. Good wood door, close the strict later enables indoor noise level lower (10-20) db. If the frame is covered with sealing around, totals may reduce the noise level (14-18) db.
If outdoor noisy, recommends installing double window. Generic windowsill in width about living room (12-15) cm, then the window edge with a layer of glass Windows, dustproof, anti-noise, warm effect. Double glass window reduces outside noise (14-18) db; if and then covered with sealing, reduces (18-20) db. If conditions allow, you can install the aluminum alloy window, make the push-pull, space-saving, easy to use, difficult to deformation, tightness, its performance is better than steel window. If the installed air conditioner, air conditioning pipe is divided into the air, and also the noise gate; if installed TV room antenna, antenna into the side is a noise gate. Should these pipeline extremely interface noise handling.
Curtains, blinds and tapestry, etc. are important sound-absorbing materials, and a comparison of exquisite luxury decoration. As with velvet peace velvet curtain, curtain material, to reduce the reflection of sound waves and Windows of resonance. Velveteen do curtains absorption coefficient 0.31-0.47, long fiber do curtains absorption coefficient 0.15-0.27, which is made of double velvet drapery maximum sound absorption coefficient, 0.69-0.82.
2. the side treatment room
Response surface for sound insulation, sound absorption. It is best to lay the carpet, it's the sound absorption, sound effects is ideal. Typically, General Hua fiber rug 0.5-0.71, while the real wool carpets of sound absorption coefficient of about 0.68-0.82. Erection of a wooden floor is better, if limited to conditions instead of Mount Batten. Wooden floor of sound absorption coefficient of about 0.03--0.05. sometimes when people are willing to stick laying plastic bricks or tiles, acoustic and sound insulation, sound absorption coefficient of plastics floor 0.02 =--0.04, terrazzo scene sound absorption coefficient of about 0.01--0.03.
The ceiling is also an important way to introduce noise. The quality is poor, a thin slab ceiling is easy to transport on a roof, beautiful and sound effects to the room height is small.
Also on the walls. Ordinary dry plaster walls are brick, its sound absorption coefficient is very small, about 0.02--0.04 can put four walls made of wooden wall; or make the wood wainscots, height from (0.8-1) m, vinyl from the wall should be at arm's length, not less than 4cm, in wall cavities, formed between low-frequency acoustic effects may be increased. Wood wainscots specific practices can have many kind, users can make updates as I could to branch to the wall to 7 as a wave, the arc-type, patches, etc., can more with obviously improve the acoustic conditions in the engine. Usually more white-washed walls or spray, spray paint off ash, colour spray or other coatings, their sound-absorbing effect. And conditions are available in wall, wall hanging distance from care ornament cloth wall (3-5) cm. This can enhance the effect of sound absorbing wall cloth, and beautify the Interior.
3, indoor furniture, furnishings
(1) typical data
Many families can enjoy music, MTV, and guests, audio-visual and aesthetics. Now ordinary room height are relatively low, only (2.4-2.8) m, in order to take account of the effects of listening, you should make the length and width of close to 1.7: 1. General room area is greater than 15 square meters, in order to replay sound, make two speaker spacing around (2-2.5) m, conducive to expand stereo like group.
(2) display techniques
Indoor furniture of a substantial and should strive to use a convenient and elegant rooms. Furnishings furniture, try not to get symmetrical to prevent acoustic colouring. Vibration caused by indoor do not place objects, such as metal art, shell thin lightweight spied, their vibration affects playback effect.
The room are placed inside the Cabinet, wardrobe, bedroom, large sofa, on improving the absorption effect is obvious, especially to improve low-frequency effect is particularly pronounced. General room cannot install perforated Panel cavity and therefore not easy to absorb low frequency. After placing the wardrobe can overcome this drawback.
Windows hangs the thick curtains, wall hanging wall carpet, floor carpet, bed spread bedspreads, etc, you can improve the acoustic conditions. Blinds on the low frequency of transmission quality is very good, and the Windows on the low frequency sound absorbing performance better, they have a complementary role.
(3) the reverberation time fine-tuning
Reverberation time should be controlled in a certain range. If reverberation time is too long, the sound is smearing, ECHO, you can lay the carpet and curtains, to increase the absorption capacity, and even indoor decoration doll, plush toys, flowers, plants and pots, and so on, you can improve the sound-absorbing effect. If reverberation time is too short, sounds dry, should increase the reflector, could hang hanging glass mirrors, framed pictures of the large glass and so on, to improve indoor acoustics.
Improve the sound quality is also a lot of ways, such as indoor pendant, wall hanging various paintings or hanging crafts paste and so on, are not only beautify environment, also to improve reflection characteristics. Some enthusiasts in the Interior shelves, are placed on a shelf full of the sizes of books, magazines, or cd album, analog recordings, etc., these articles on Sonic with absorbent, reflex, ore in bulk; proof reset each shelf sizes, widths of different books, can produce irregular surfaces. For those not easily handle large reflective wall, try placing it on the shelf, but also to improve listening. In short, through a range of adjustment measures, finally let people hear speakers-sounding voices.
