I remember someone said: The real HI-END is the room. It can be seen that for an enthusiast, how important it is to have an ideal listening environment, it will affect the sound, dynamics, image, and positioning of many fever elements. Therefore, a space with good acoustic characteristics will get twice the result with half the effort.
The listening room can generally be divided into two types: one is open type and the other is closed type. The open type is shared with the living room. This kind of environment cannot be independent because of the doors, windows, aisles, or the combination of audio-visual, meeting, and dining. The sound is only allowed to flow. Because of the limited conditions, the speaker can’t be placed. Do whatever you want. The enclosed space is the dream of the vast number of fans. The listening room can enjoy music under relatively closed conditions. As long as the sound insulation is well handled, it is generally not susceptible to outside interference, nor will it affect the family or interfere with the neighbors. (I feel quite touched), the placement and flexibility of equipment and speakers are large, and the tuning of the listening room is also plastic. In addition, because the environment is relatively closed, and there is no concern about energy leakage, the quality of the low frequency is guaranteed. Compared with the open type, when choosing a listening room, the space is smaller, even if it is only more than ten square meters, as long as the adjustment is done, the small environment can be seen in small. Welcome to the Chinese home theater in the decoration and adjustment of the listening room, I am most admired is the handling of the wolf version of the listening room, and my current listening room is generally large, but the sound performance is very good. Of course, this is the return of his efforts, time and money. It is said that the renovation of the sound room is no less than five times. The interior wall is demolished, demolished, and constantly smashed. His emphasis on the listening environment! In addition, in the Zhenjiang professional listening room, it is the acoustic treatment of the second audition room of the piano sound. Of course, our civilian listening room can refer to it. You may wish to take a look and listen.
Closer to home, I have not known that my "burning age" has been nearly ten years, but the level has not grown much, but during the period there were two experiences of changing the listening room, more or less able to sum up some lessons and experience to come with everyone. Share, I hope to provide some reference and help to friends who need it:
First, if the conditions permit, the choice of listening room should be large or not, generally there is a good two or thirty squares, if there is a golden ratio (length: width: height = 1.618: 1: 0.618) More ideal. My feeling is: if the space is big, the sound will sound more stretched. My first audio-visual room has 26.5 square meters (in the living room, AV and HI-FI, but not open), now only 14 squares of independent, the difference between the sound performance of the front and the back is quite large.
Second, the listening room decoration should try to follow: the principle of hard, sucking and post-diffusion. When I renovated the second listening room, the front wall was only painted white, and then a piece of wood carving was hung. The actual listening feeling was not enough "hard", so I recently had to buy a cultural stone sticker. In addition, the front bass trap is sucked more, this time adding some lines to increase the reflection.
Before the second listening room was remodeled:
After the minor change:
Third, the doors and windows, ceilings and floors should be solid and firm, otherwise it will cause resonance when the sound pressure is large or when replaying the ultra-low frequency, it sounds very uncomfortable. In my first audio-visual room, a wooden sliding door was added between the kitchen and the living room as a partition. At that time, in order to transmit light, glass was added. When the low frequency came, I heard a creaking sound, and later added The sealing strip is better. In addition, the ceiling of the two listening rooms have used foam diffusers, and the effect is good. There is a window on the left side of the second listening room, and it is decisively sealed off to make it "after trouble." In addition, the door can be made as thick as possible, and the effect of reducing resonance can be achieved.

The ceiling of the second listening room:
Fourth, the walls on both sides of the listening room should avoid excessive sound absorption, otherwise the harmonics in the music will be short, the overtones will be absent, and the low frequency will be lost. The walls on both sides of my first audio-visual room are mainly light walls. The sound absorption is only done at the main diffusion and the first reflection point. In addition, several wooden boards are hung on both sides to increase the diffusion. The effect is good. When building the second listening room, considering that the room is small, the walls on both sides have adopted a full sound absorption treatment. Who knows that this practice proves that I am wrong and has the opportunity to toss.

On the right side wall, there is a window below the air conditioner:
The first listening room is expanded and processed:
Fifth, the floor of the listening room is best to lay solid wood flooring, and the carpet in front of the listening area is better, so the tone will be warmer. However, it should be noted that the cavity between the floor ribs must be filled, otherwise the low-frequency energy will be greatly reduced. Many friends may not have noticed this, and I would like to remind you here.
Sixth, power supply should be strong, I think this is the most basic requirement to ensure good sound, and not much money. In the front and back of the two listening rooms, I took the three-way independent 4 square power cord directly from the meter box. Conditionally, I can use 6 square or 10 square lines, but the power supply for the audio source is best. Do not exceed 6 square feet, otherwise the sound will be thick. Also note that it is absolutely impossible to pull a cable that is 10 square meters to be used as a power source, and then to pick up a board. This way, even if you use a price-grade power cord, you can only helplessly and helplessly.
Three independent power supplies:
Seven, it is best to set up a dedicated audio ground, buy a land bar does not cost much (hundreds of dollars), but the actual gain is far from this, you will get a quiet background, the jargon is "the background is very dark ". My two listening rooms are all connected to the ground wire and the ground is really clean.
Eight, listen to the sound room before the renovation to do more homework, should not be so arbitrary like me: think that the room is small to absorb more sound, but also should ask more experts, so that you can take less detours. By the way, after the decoration of the listening room, the adjustment should be gradual and patient. Never change the machine when you are not adjusted, and waste money!
At present, my listening room has to work hard to spread, in an effort to achieve better results. This is: burning road bends, I will be eager to find it! The above is a little superficial view of the decoration room of the monks. Please give us a lot of suggestions.
