[Home Theater Network HDAV.com.cn] Listening to the sound space is the final link of the audio system sound playback, not only affects the sound of the HIFI listening room, but also affects the sound playback of the home theater. More and more enthusiasts realize that the listening space has an impact on the sound, and thus the phrase "big burning room".
How does the listening space change the sound?
When the sound wave is emitted from the speaker, as long as the speaker is in a closed space, the sound wave must receive the distortion of the wall of the confined space. Some enthusiasts take it for granted that if the walls are all made with strong sound absorption, then the speakers are placed in a space similar to the borderless, and the listening can only hear the direct sound, which is the most accurate sound. People who have such naive thoughts have never listened to music in a strong sound-absorbing environment, or have spoken in it.
Such a strong sound absorption environment is actually a muffler room. Anyone who has been to the muffler room knows that the voices that speak inside will sound very uncomfortable, let alone listen. In the case of direct sound, the sound is thin and the sound pressure is small, so the dry sound is very unpleasant.
Objects such as furniture in the walls of confined spaces and spaces in the space cause sound waves to be reflected, refracted, diffracted, and resonated on the surfaces of objects in the room, and superimposed on each other. Poor handling will result in many peaks, valleys, and sounds, but When processed, you will get full, clear sound quality, and a wide and deep sound field playback.
At present, most enthusiasts do not have a dedicated independent listening room, usually from the living room, study, bedroom. Here, I teach you some small ways to use the furniture in the room and the soft decoration that comes with you to get a good acoustic space in the home environment.
First, how to eliminate standing waves as much as possible
The generation of standing waves is closely related to the ratio of length to width of the room. This ratio should be irrational, preferably golden, ie 1:0.618. Most avoid the integer ratio. However, the home space cannot be changed at will. It does not matter. Large furniture is placed in the corner position, and standing waves, such as bookcases, wardrobes, etc., may also be absorbed. It should be noted that if used to absorb standing waves, the furniture must have a certain height. Use large pieces of furniture to adjust the angle in the corner several times, combined with the sense of hearing, you can also get a sturdy and flexible low frequency.
Second, how to get clear sound quality
The reverberation time is too long and the sound is prone to turbidity. The family enjoys music, and the reverberation time is controlled at 0.3-0.8 seconds. Generally, the rooms are long and the solution is to add soft objects. Such as carpets, curtains, soft sofas, soft decorative paintings, etc. It should be noted that try to use thicker soft objects. If the soft objects used are relatively thin, do not use them in large quantities. This will cause high frequency loss and sound boring. As a whole, if you are debugging at home, try to start debugging as small as possible. Do not listen too much. The problem with most audiophiles in the listening environment is that they are over-sucking, causing a thin dryness.
Third, how to avoid acoustic dyeing
There are no things that can cause harmonic shock in the room, such as: weak glass, air conditioning vents of aluminum grid, large-area radiators, etc.
to sum up:
Just by following the above steps, solve the standing wave, reverberation time and sound coloring, you can get a listening room with clear and compact low frequency and clear sound quality. Many audiophiles in the listening room have no traces of professional acoustic processing, but the sound is not bad, it is because of the use of household items for debugging. As long as you compare the sense of hearing, each enthusiast will have a good listening environment. To add, the above description also applies to home theater space.
