Talking about the decoration of the listening room and chatting with a senior overseas audio fan, what is the highest-ranking enthusiast who is playing? Answer: "Play space, play the environment." I was surprised: "Isn't that just burning a house, 'burning' decoration?"
The friend nodded and said: "A set of 1 million equipment is in a bad listening space, and the effect is sometimes not as good as a set of 100,000 yuan. And when you spend 1 million to decorate this room, if it is illegal, the effect is even It's worse than the 10,000-square-decorated room! There are so many variables in this!"
Obviously, the creation of listening space is a very important topic for high-standard audio enthusiasts. It means that it will make your beloved equipment depreciate in sound.
Nowadays, the housing conditions of urban residents have been greatly improved. Many friends have begun to consider creating a space for listening to music when they are buying and renovating. In fact, the creation of a good listening space involves many disciplines. It will involve a variety of expertise in electrical engineering, acoustics, material physics, civil engineering, and decorative design. For the time being, in general decorating companies, designers simply can't provide you with a complete set of "sound room solutions" that combine sound and decorative effects. For ordinary people, buying a house and decorating a home is a rare event that can't be repeated, and there is no chance to reinvent it. Therefore, the construction of the listening room by the laymen will make money and energy go to waste. Some renderings seem to have a sound listening room, but when the dust settles, the actual sound effect is often frustrating; some people emphasize the listening effect during the decoration, the result is messy, the home is not like home To make the limited living space lack the warmth that it should have.
So how do you plan and construct an ideal home listening space? Here, the author combines his accumulated experience to list some points that must be paid attention to and provide them for your reference.
1. Choice of room type This is the first step and the most crucial step. Choosing the wrong one means that your future fever dream will be completely destroyed. Even if you stick the banknotes on the wall and spread it underground, the effect will not be tolerated.
Remember: When buying a house, try not to plan the room with a polygonal plane as your listening space. Also don't think about square-flat rooms. A proportional rectangle, or trapezoidal plane space will be perfect for you.
The acoustic and architectural worlds have many theories about the "golden ratio" of the ideal acoustic space, of which a more classical one is 1:1.6:2.6 (height: width: length). This is based on the "golden ratio" law of 1:1.6180339887 discovered by the ancient Greek mathematician Fepanisi. It is said that some ancient instruments are made according to this ratio, and some of the best in the world. The sound theaters are mostly close to the proportion of this "shoe box shape".
At present, few real estate developers specialize in developing special room types for audiophiles. Therefore, it is almost impossible to find a room that meets the "golden ratio" while satisfying your other requirements. You can find a room with a relatively close ratio. It is already very good. However, you can rebuild the rough house to achieve a "golden ratio" without destroying the structure. However, the price paid will be more expensive.
In fact, the vast majority of people are not obsessed enthusiasts. Due to conditions, they will consider using the living room as a listening room or home theater. Most people will use a long wall to place equipment, and then use the other side of the wall to seat the sofa and other seats. This seems reasonable, but unfortunately, this usually does not bring perfect sound. The ideal living room and listening room should be the equipment and the seats on the two short sides of the room.
2. Power concealment project:
The pre-burial of the line is usually the beginning of the renovation project. The power supply is the most important thing in an ideal listening room. The power supply of the listening room is well done, and with the AC power supply filter, isolation and voltage regulation and other AC processing equipment, it will definitely make the sound system even more powerful. On the contrary, even if you use advanced power processing equipment for remediation in the future, it will be half the battle. Therefore, the concealment of the power supply requires very careful planning and careful construction for the construction of the listening room.
Expert research shows that our living space is full of so-called RFI (radio frequency interference) and EMI (electromagnetic interference), which may come from your home's air conditioners, refrigerators and other heavy-duty appliances; it may also come from neighbors' radios, computers; Cars on the road, pedestrians' mobile phones, etc. The AC power cord of the audio system, if not handled properly, will become an "antenna" for picking up these noises. In fact, the sound system is quite sensitive to these "invisible disturbances", and they make the music transmitted by the speakers unpurified. Welcome to China Home Theater Network
To avoid these disturbances, it is extremely effective to start from the listening space. The most basic treatment method is: arrange a separate circuit for the listening room power supply, so that it is separated from other electrical circuits of the home when entering the house; in addition, when the line is buried, add a PVC bushing to the power line (if You also need to pre-embed the surround speaker cable, audio and video signal cable, or TV RF cable, and also use PVC sleeves. At the same time, try to keep the listening space away from computers and microwave ovens because they are the largest source of electromagnetic interference in the home. In addition, in the listening room, you should also avoid the use of variable frequency air conditioners, dimmer switches and cordless phones, because the clutter generated when they work will pollute your sound system.
In order to ensure a strong and stable current supply to the power supply of the listening room, a high-quality power cord with a relatively large wire diameter and good insulation and shielding should be embedded. It is preferable that the wire has a wire diameter of 6 mm 2 or more. However, there are few such specifications for single-strand power cords such as the commercially available "Panda". All of them use a dedicated audio power cord, and the cost is almost impossible. How to do? You may wish to order a special sheathed wire at a professional electric shop. This is a two-phase power cord with a size of 6 square millimeters or more. It is equipped with a common 4 square millimeter single strand for grounding. It can form a three-phase power supply and can also receive good results.
In addition, the specifications of the listening room power outlet should generally be 250V/16A to be able to adapt to high power amplifiers. At the same time, high-quality products should be selected as much as possible to avoid arcing discharge, transient noise generation, damage to equipment or deterioration of signal quality. Since the power plugs of most fever equipment are mostly three-phase plugs of the British and American systems, the socket system, usage and approximate position of the listening room should also be planned in advance to avoid unnecessary conversion after the equipment plug is not matched in the future. Like Italy's "Feimai", the Sino-Western joint venture "Simon", there are American-made, English-made three-phase power socket supply, the quality is very good, it is worth recommending to enthusiasts.

Some enthusiasts have the experience that the current leakage switch protector should not be used on the power supply circuit of the listening room, because the air switch can also cause the power supply to be impure. They recommend using a special fuse to prevent short circuits. Instead of using ordinary tin wire, this fuse uses high-purity oxygen-free copper wire. It must be emphasized that the thickness and load of the copper wire must be accurately calculated so that its melting point is consistent with the usual tin fuse for safety purposes.
In addition, some enthusiasts will also work on the grounding of the power supply. They will bury the ground wire deeper than the ground, and conduct electricity with the underground water pipes, and inject a large amount of salt into the ground wire. They believe that this can be There are many sounds in the sound. However, this approach sounds a bit superstitious and lacks scientific basis. It can only be used as a "playing method" for reference. The author does not recommend non-fans to try.
