The stand or fall of replay sound audio equipment, acoustic characteristics and the building of the listening environment has a very close relationship, to make the sound system play the highest performance, must make certain acoustic processing on listening room.

For architectural acoustics characteristic of listening room, there are four aspects need to consider that (1) the reverberation time, (2) the dispersion characteristics of the reverberation decay, (3) the frequency characteristics of the room, (4) environmental noise sound level. J; U!!! Ka# Ge

Listening room architectural acoustics characteristics of each are not identical, different objects to sound reflection and absorption are different, so to improve the listening environment acoustic processing, improve the acoustic defects in work is very complicated. As long as possible, it is best to avoid any room the size of the two sides are equal, or one side is on the other side of the two times, which is a square or aspect ratio is double room, and because the proportion of room will produce a standing wave, low frequency acoustic resonance, cause staining.

Room from the wall, ceiling, floor, furniture and personal formed by repeatedly reflected sound persist, gradually decay phenomenon, known as reverberation (rever beration, also known as reverberation). It's different from the echo (echo), the echo is not a smooth attenuation but voice suddenly returned. The most important indicators for indoor acoustics, first of all, is the reverberation time, it is the sound energy decay down to one over one million of the original strength (60 db) the time required, for a room have been identified, reverberation time mainly depends on the sound absorption treatment. For the Hi - Fi listening room reverberation time, preferable 0.4 ~ 0.5 seconds. Reverberation time reasonably can make music fullness, voice and sound reverberation time is longer than the more lively character, but it's too long voice easily confused, intelligibility, too weak and rhythm, sound reverberation time is too short, a hard, lack of angry, no reverberation sound is often inflexible sense (outdoor).

Dispersion characteristics of the room is good, the attenuation of sound smooth, indoor everywhere feel even sound. Any convex has spread the ability of sound waves, including slope, surface and convex cambered surface, when you need to spread the acoustic frequency to convex, diffusion plate can be used for processing.

When a certain frequency of sound due to some reason to get too much more or less, will break the uniformity of the sound in the rooms, this kind of phenomenon we call dyeing (sound ation). For example, a standing wave can change the original features of the voice, appeared in some spectrum peak, improve methods of indoor items put avoid symmetry.

The listening room of large space is not only helpful to low frequency extension, also can make the sound feeling more relaxed, more sense of live birth. Our country generally used as a listening room bedroom area of about 14 m2, 2.8 m high, volume of about 40 m3. In the room, as long as the acoustic processing properly, should be able to have a good sound effect. Due to below 100 hz the wavelength of sound is greater than 3.4 m, and the size of the room in the same order of magnitude, so in the space can only produce several resonant frequency, low frequency sound waves of interference is less, sounds appear natural fruity. But, in the high frequency sound wave in the long run is smaller than the space dimension, it will produce a large number of standing wave indoors, under the mutual interference of standing wave, the acoustic characteristics of the room in 100 ~ 500 hz is generally poor, and the audio frequency band energy is very high, so want to pay attention to, make appropriate treatment.

Room between the wall of the relative, as a result of the multiple reflection of sound standing wave (standing waves), as a standing wave occurs can produce resonance, the frequency depends on the distance between the walls, visible room is actually a resonator. Dye room acoustic standing wave generated the most, is the speakers on both sides of the back wall of the corner of the room, it will reflect not clean bass, this effect is called rumble room (room booming). The low frequency acoustic defects, a standing wave is a common cause the loss of bass clarity, needs to be handled with care. A good way to control the standing wave reflection is to use the shelf full of books, books of irregular shape and not too strong absorption effect, can make the sound waves to scatter, so as to reduce the influence of sound reflection. Marble and granite floor and ground glass is the first choice for modern home decoration, but it is an enemy of acoustics. Often lead to fuzzy noisy sound, improve methods of carpet is a proper size at the front speakers and add thick curtains in front of the glass.

Environmental noise level refers to the interior noise sound pressure level there is no sound, such as environmental noise is too high, can adopt methods of sound insulation, isolation, or in the indoor laid a certain sound-absorbing material. For the current amount of sound insulation of the bedroom is often not enough, and the whole room with a solid wall of sound insulation, best sound insulation the weakest of the door, window, so important factor in determining the quality of sound interatrial septum is a door and window

The sitting room used as listening room in the bedroom is not ideal, because the sitting room is the space of open mode, general aisles are caused by asymmetry of the space, plus French window, thereby causing loss to the low frequency extension of space make it difficult to control the sound reflection, audio-visual offset. As long as don't have much furniture, bedroom listening room is a better choice, because airtight space problem easier to master the sound reflection.
