To get a good sound, must have a good environment. If poor acoustic conditions of the room, no matter how expensive the equipment is no longer so send in. Many enthusiasts have a "one-third equipment, seven environmental" feeling, which shows the importance of acoustic renovation. As a professional home theater audio-visual room, we want to achieve what conditions is considered a good acoustic environment? A wall treatment in general, we are mostly brick walls. This wall for high, medium and low frequency reflections are strong, especially for the high-frequency reflection. Therefore, the "appropriate" to become the primary task of absorbing. The so-called proper is not too much, if the sounds are sucked dry flat without charm, it counterproductive. Sidewall treatment in the end how to suck it four walls is appropriate it? Let me talk about two sidewalls. Here is the first to deal with the issue reflected sound from the speakers come. Why suck first reflected sound? If the first reflected sound too much, it will lead to the positioning is not clear, but also noisy sounds. So be sure to suck. How to suck? You do not have the whole wall full of sound-absorbing, just about in the middle of the speaker and the listening position can be absorbing. This area probably absorbing much? At least 1-1.5 meters wide, two-thirds of the height of the wall height. Common sound-absorbing materials are mineral wool, glass wool, polyester sound-absorbing cotton, polyester sound-absorbing cotton is better, can be made in the form of a soft bag, but please note, do not think you can nail the wood acoustic, wood surface is flat, and The original wall is no different. Hard wood itself, but also with the wall is no different, it does not have sound-absorbing effect. Horn speaker back wall back wall must be strong handle to be hard, so as not to suck the low frequency, and make power doubler amplifier. If you nail the back wall of the cavity in the speaker, no matter how thick you are using wood or sheet, absolutely have only a negative impact but no positive results. The most common negative impact is the sound Xu Xu, the sense of low volume is not enough, not strong, but low? Unclean. Huh? Since the horn back wall should be strong to be hard, you just have to suck how to say it? I call you not to get sucked cavity, but to the same as the side wall suction method. Please note that if you do, after absorbing the two side walls, already feel precise positioning, and the sound is not noisy, then you can not do the back wall speaker acoustic treatment. Conversely, if you still feel the sound is too noisy, positioning is not accurate, then they would have done in the horn back wall acoustic treatment. After a back wall suction to ensure the sound changed. Horn handle any corner of the back wall of the corner is standing where the strongest, if we can handle a little, it would be useful for sound absolutely. If not addressed, in fact, it does not produce great harm. The most natural treatment is to not spend the corner designed shelves, CD rack or shelf decorations. Some people will use wood to seal up the right angle, so that it becomes an oblique angle rather than a right angle. This is useful, but will still run the risk of low frequency absorption of the bevel of the cavity. That was then made at right angles to the arc, the arc having a diffusion effect of sound waves. However, still bear the risk of the cavity to absorb low frequencies. How do you want to listen to the position of the back wall Perhaps you will say, I have to sit close to the back wall, but also how to do this piece of wall? Honestly, sit close to the back wall is the worst, because the sound would be more muddy. Unless your system is less than the low-frequency, must be close to the back wall to enhance the low frequency. In general, your seat at least half a meter away from the back wall, so the sound will be relatively clean. This piece of the wall behind the listening position can actually suck, it can be spread. By suction is too close to the back wall of your fear, reflected sound too. Because diffusion is far from the back wall, the diffusion can make the sound more natural. The best way is to use sound-absorbing material in the shape of the surface diffusion, so that the absorption and diffusion of the benefits of both, this is the most perfect. Two ceiling and the floor of the processing on the ground floor furnished home are probably marble, tile or wood floors. In order to reduce the reflection from the floor up the bass, we still need in this land between the speaker and the listening position covered with removable thick carpet. Please note that I said thick carpet, rather than the general South Asian thin carpet. Why do you need a thick carpet? Because a thick carpet of sound-absorbing effect is enough, if you just want to use small pieces of thin carpet, it will be only a decorative role, but there is no real sound-absorbing effect. Ceiling deal in general, but also the best sound-absorbing ceiling and diffusion of both, so the sound will be better. If only spread from the ceiling to the high-frequency sounds will be too reflective. Smallpox has about several approaches: a light steel frame plus mineral fiber board which is the easiest ceiling deal is the most economical process. Although this ceiling effect only absorb high frequencies without any flooding, but had to suppress high-frequency noise and echo will be effective indoor long. Second, the caisson plus central area called acoustic caisson is a princess, a close up of the layers of the ceiling, the ceiling of old Chinese architecture can often see such a deal, Shanghai and Beijing Concert Hall has such a deal. Caisson role is within the diffusion layers shrink the ladder, and its absorption is placed in the middle of that piece. Caisson any harm? First, please do carpentry quite expensive. Second, the caisson cavity itself will absorb the low frequency. However, if your sound absorption, diffusion is not enough, but he likes the beautiful caisson, caisson probably still a good choice. Third, the diffusion plate hole hole board Decapolis Jian Caixing board is able to buy the kind of full of holes in the sheet. The two feet square hole cut into a board, and then hole up the side of the plate covered with foam or absorbent cotton, then place them in the light steel frame. Put half the entire tunnel ceiling panels like the rest of the half light steel frame is put Polly diffuser plate. As a result, hole board may sound absorption, Polly diffuser plate can spread throughout the ceiling with them not ugly. Huiyuan Technology Co., Ltd. Foshan-0757-85706440 13902767561
