Who have a high-quality sound audio-visual room is all music fans dream. We should note that a uniform sound field, the warm audiophile sound space is all dream of. In the Silent King indoor deadening and sound-absorbing material of a large number of movie theater room decorated in the Army, we already have some basic understanding of the formation of acoustic space systems, such as the proportion of the room, speaker placement, etc. In today's article, we will be introduced for the diffusion and acoustic materials, acoustic treatment and other sounds. Flex visual tone of the room, the home is decorated with warm colors and cool colors of the points, for audio space, the rooms also have soft and hard points. Our multi-room home is made of brick or cement poured six parallel walls, these hard walls for sound energy to reflect mainly they called hard tone space. Hard tone space and lack of sound-absorbing material diffused reflection of sound energy strong and harsh noisy, low frequency will also increase. Instead, the wall with wood, gypsum board was divided into between the board and the board as well as environmental noise, such as cotton, mezzanine room for soft tone space, this space is for high, medium and low frequency sound energy will make certain absorption sound bigger load, whether large dynamic sound field reproduction and audiovisual space better than the hard tone, so the ideal listening room should be soft tone space. Architecture is frozen music - Friedrich von Schelling to understand the impact and the importance of listening to the sound processing space is very important. We know that the human ear can hear our voice range (20Hz-20kHz), due to the high and the shorter wavelength bands, their reflections are the main factors affecting the sound, but the longer wavelength, low frequency is easy produce standing waves, so we can have a different approach for the sound of different frequency bands. For a small space video room, because the direct sound is large enough, the reflected acoustic sound interfering factors, need to be properly controlled. The main auditorium spatial processing is to reduce low frequency standing waves and interior resonance and resonance frequency sounds. Take full frequency efficient absorbent cotton, acoustic insulation unified acoustic insulation blankets would be the most effective treatment diffusion standing method, uniform sound field generated by diffusion through this, is the dream of all the audiophile. Important approach - diffusing, by definition, refers to the sound expansion and spread in all directions mean, the point is the "spread" to make all kinds of frequency sounds mixed together, spread to the entire space. Directional sound weakened, the sense of hearing becomes stable, relaxation. And we usually refer to the diffusion of sound craving refers to a region in the energy density, as the passage of the energy of the probability of the same sound in all directions. From the sound emitted by the speaker to convey to us the human ear sounds are mainly direct sound and reflected sound, due to space and speaker placement and other factors, reflected sound easy and direct sound with a frequency of sound interference leaving compromised, people feel the sound chaotic. Diffusion can be a good solution to this situation, the sound was broken up at various reflex points, directional weakened and interfere with the direct sound frequency caused greatly reduced, resulting in a uniform sound field effect. Acoustic listening room wall decoration handle each wall by the front wall and more hard, sound-absorbing side wall around the principle of diffusion to the back wall decoration, decoration in the theater room above 5.1 are basically the same. Left side wall: about sidewall is where speakers emit sound after the first direct reflection, in the case of a large listening space, in the first reflection point for the diffusion process (if space is not the case, we recommend using the mute King gradient sound-absorbing cotton made of acoustic treatment) can help clear positioning pan, clean and not so noisy sound. Large space easily withstand greater sound pressure, sound diffusion so that more details will not be lost. Because of the small space can not afford sound pressure, acoustic treatment can be made. But imagine, too much information in the acoustic sound is bound to some minor details absorbed in the sound pressure is not the case it is difficult to hear the details, but the volume is too large may make people at large dynamic sound difficult endure, so we take into account the details of the reduction and sound loud to bear the pressure of the case, should be more selective diffusion effect of a good decoration. Floors and ceilings: floor and ceiling decoration auditorium is also very important, and now most of the multi-floor bedroom is paved marble, tile or wood floors. From the material point of view, wood floors most conducive sound effects. In experience, two, thirty square meters spread overhead wooden floor room with 10-inch woofer speaker bass and get a lot. In fact, the lack of a sense of low volume, the most important reason is because the high-frequency reflective listening too much space, so you can not listen at high volume, low-power zoom simply can not put the original low-frequency "forced" out of a sense of imbalance caused by the amount of the full frequency . Tile flooring is easy to clean, but are likely to cause high-frequency too noisy, is to solve this problem on a tile floor was about 2-3 meters thick carpet or ceiling using the acoustic treatment. Best sound-absorbing ceiling and diffusion of both, or only hard tone diffusion or all soft tone of voice will make a high-frequency sound-absorbing sound reflections will be too strong or too weak. Doors: doors and windows of the processing course, have some soundproofing. Because of the heavier the better noise performance quality objects, so it should be possible to select heavy door. The quality of the door structure is the main factor affecting noise performance while handling the door can not be ignored. Now commercially available regular fire doors have some soundproofing, they are filled with sound-absorbing effect of the internal fire retardant, high-frequency acoustic full mute king cotton polyester fiber acoustic sound-absorbing material, such as environmental protection, the door sound barrier mat You can also play the role of noise. Other audio processing: Avoid indoor items placed symmetrically, and leather sofas placed in the auditorium, the commoner sofa, wooden table, wooden shelves, racks and bonsai sound so you can make the room sound more warm and comfortable. And at the same time minimize the release of sound reflection and strong vibrations caused by the large glass case easy and lightweight metal painting exhibit furnishings, etc., but when you put a book or CD disc or do not neatly packed to the brim, Let them ups and downs, patchwork, will increase while the reflective surface diffusion.
