Now more and more friends like to engage in a listening room, especially high-fidelity and large screen. After enjoying the group equipment, the sound effect is not necessarily satisfactory. When considering the sound quality, you can improve the listening space. Acoustic environment to make the sound more ideal.
The sound from the sound source in the room is transmitted to the listener's ear through six channels, the direct sound of 1 speaker, the reflection of 2 floors, the reflection of 3 ceilings, the reflection of the back wall of 4 speakers, 5 The reflection of the walls on both sides, 6 the reflection of the wall behind the listener. As long as any reflection condition of the sound wave is changed, the sound changes. The intensity of the reflected sound must be appropriate.
For such a private listening room, its listening environment largely determines the sound quality of the replay sound, the best equipment, poor environment, and difficult to have good results, but this is often overlooked. The acoustic characteristics of the room are largely related to the interior and room layout. The shape and size of the ideal listening room should be in the golden ratio, and the three sizes (length, width, height) should not be integer multiples, so that the influence of the standing wave in the room is reduced, and the sense of hearing is improved. Secondly, it is necessary to make sound insulation, so that the inside and outside of the room will not interfere, and the sound will be diffused, and appropriate sound absorption should be provided to avoid the sound reciprocating reflection of sound waves to excite some natural frequency (normal frequency) sound interference, resulting in acoustic dyeing. Love HIFI audio network found that in real life, the acoustic characteristics of the listening room is generally not ideal, so if the quality of the sound is very high, in addition to the signal source, equipment, but also some acoustic treatment of the room.
Here the Chinese Home Theater Network gives you some advice on the acoustic treatment of the room, focusing on the side walls and ceilings. In principle, indoor sound waves should be treated more diffusely than absorbed, in order to reduce the resonance intensity, and to prevent excessive use of sound absorbing materials, so as to avoid the room's reverberation time is too short (< 0.3 seconds) to make the sound dry and not round. For the wall behind the speaker, it is best not to have a large piece of sound-absorbing material, usually no need to deal with it, brick wall or cement wall will make the sound full and full of vitality.
Simple improvement method:
The acoustically treated side wall of the listening room can uniformly and appropriately set some sound absorption and diffusion materials. For example, a thick wool blanket is an excellent full-frequency sound absorbing object, and the thin carpet and the tapestry only absorb the medium and high frequency. The wooden doorless bookcase is a good sound diffuser, which is good for adjusting the low frequency. Love HIFI audio network based on years of experience in the decoration of the audio-visual room, prove that tables, chairs, mattresses, sofas and other furniture can adjust the sound transmission, can be used as acoustic treatment. The most ideal acoustic treatment is to put a suitable diffuser on the side wall, but it is expensive and affects the appearance, which is difficult for the general family to accept. The convex arc is a good device for sound diffusion and sound absorption, and can be suitably used. In the sound absorbing process, the lower half of the wall is more important than the upper half, and can be treated with a resonant sound absorbing structure such as a perforated plate or a thin plate.
Thin carpets, curtains, tapestries, etc. mainly absorb the middle and high frequencies, and have little effect on the low frequency sound absorption. Too much use will cause the reverberation time of the medium and high frequency sounds in the room to be short, making the sound Lack of color, not bright enough. Wooden boards and other wooden boards can effectively absorb low frequencies, but there should be appropriate gaps between the walls and the walls when necessary. If necessary, place sound-absorbing materials in between.
Finally, the Chinese Home Theater Network reminds everyone that when decorating, remember not to nail a large number of splints to the wall, and do not apply a large number of sound-absorbing blankets and curtains in the room. Otherwise, because the high frequency is absorbed a lot, it will cause the sound to dry, the details are reduced, and the volume is reduced. I hope everyone can have their own listening environment.
