The matching of equipment is a terrible thing. When you open the audio magazine, you are asked to figure out how many brands are in the world. I believe no one is bold enough to give you the answer. Plus, each brand will produce different models, each brand. The tone color orientation is different. Even if you have the ability to match the equipment with this, you can only rely on experience (sometimes intuition) to match the only equipment or wire on the head. Is it appropriate? The test results are often used. Arguing, so you can only refer to it.
Let's talk about other basic factors that affect sound. It is also because of these factors that enthusiasts have something to play with, and to understand these factors, the school sounds will definitely help a lot. The first is the environmental factor, and the second is the human factor. Here we only talk about the environmental factors, which are the most complicated, because it includes the following characteristics: 1. Listening to the resonance characteristics of the environment; 2. External vibration; 3. The vibration of the sound returning; 4. The acoustics of the listening room characteristic
If the resonance characteristics of the environment are tested with a spectrum test analyzer, the frequency response characteristic curve of the room will be undulating like a dragon dance. Even if the equipment you use is advanced, it will be subject to the acoustic characteristics of the room. How do you Eliminate or alleviate the innate impact of this room, so that the response is straight, so that the combination has a good performance, it depends on your effort. The proportion of the room is easier to handle with a rectangular shape. The most taboo is the square room. The standing wave is particularly powerful and difficult to handle. The friends who know the sound well know that this is almost a death, and it is difficult to make a sound.
External vibration: Some listening rooms are close to the roadside or close to the workshop, or the next door is a lift room or pump room. It is often affected by the noise or ultra-low frequency caused by the car passing through and the machine is running, causing the audio equipment to be shaken. The sound is ambiguous. In this case, it seems that only moving the house or imitating the studio design, and making a room that is isolated from the house and floating in the house, can be avoided by making sound insulation measures.
Sound return vibration: When the sound combination works, the sound will vibrate the wall, the ceiling and the ground, and some of the direct or indirect impact sound equipment, these vibrations through different media, such as audio rack, air, etc. at different speeds and strengths Feedback to the equipment, causing the equipment to vibrate and generate its own resonance, resulting in subtle changes in the electronic flow of the equipment on the work line to make the sound change, the result of the phenomenon of blurred sound, can be said to be a distortion. Most of the accessories for audio equipment on the market, such as nail feet, wood, steel sand and other products, are produced to deal with this type of resonance.
Acoustic characteristics of the listening room: In addition to the influence of the proportional and shape on the frequency characteristics of the listening room, the materials used in the construction of each listening room, and the materials, layout, furniture, etc. Curtains and so on will change the original innate acoustic characteristics. These changes can be predicted or calculated, but many unknown factors, such as the construction of the decoration, the material of the furniture used in the future, the thickness of the carpet, the position of the decoration, etc. It is difficult to estimate, and no data is available. Even the sound engineer can't take it. Because of this, smart enthusiasts take it for granted, and they are more careful to analyze the acoustic characteristics of the room later, and then use materials that can be used for tuning on the market, or use, for example, RGP boards, Room. Ture, Sonex, diffuser and other professional materials to adjust the room characteristics, often than blindly self-righteous to stir up a mess, in the end it is difficult to pack.
