The audio system is nice. One of the most important is positioning: the relationship between space, speakers, and listeners is very important. Environmental factors can be described as a top priority in sound system (two -tone, 5.1 surround, AURO 3D, ATMOS surround sound effects). No matter which one you choose? We all expect to have a good voice experience. What we often hear the most is “to be loyal to recording” or “absolute original sound reproduction”, which is also the goal that every enthusiast will eventually achieve, so when the enthusiasts buy their favorite speakers, they hope to be in their own. The effect is immediately effective. For enthusiasts, the sound of the audio should be as close to the recording room as much as possible, and the following points need to be achieved: speaker position, space measurement and correction. So what we discuss today is one of the factors that you need to consider before buying audio: What is the relationship between the size of the speaker and the actual space?
I will definitely tell everyone here. Generally speaking, the larger the volume of the speakers, the more units, the stronger the energy wave energy, and the larger the space required. More prominent. How much space is appropriate? There are not many discussions in this regard, but the famous acoustic experts in the mainland put forward a view that the volume of the listening space is at least 200-1000 times that of the volume of the speaker bass box, otherwise it will cause negative effects. What does “bass body volume” mean? Many speakers now have independent sound boxes. The volume (cubic) of the left and right speakers independent box rooms is 200 times, which is at least the volume (cubic) listening to the space. What if the bookshelf speaker, or there is no speaker in the independent bass box room? Then use the volume of the entire box as the volume of the bass unit.
Where is the ideal placement of audio equipment? The location of the audio equipment should be avoided as much as possible as much as possible, and the corner is where low frequency sound waves are gathered. Low frequency will have a relatively strong resonance on the equipment boxes. Essence Generally, the audio shop or audio media listening room and the commentator room. Due to the convenient operation, and in order to save wiring length, the audio equipment is often placed in the middle of a pair of speakers. In fact, the area between the two speakers is also a place with strong sound wave energy energy , Not suitable for placing equipment. The position of the more appropriate placement should be the left and right sides of the room. This position can avoid the strongest part of the sound wave energy. If the sound absorption treatment can be performed on the side wall of the equipment, and the reflex sound of the wall can be absorbed. will be better.
If the audio equipment is forced between the speakers, to reduce the vibration effect on the equipment, will the equipment stand with a better vibration -suppressing sound capacity be one of the solutions? If you are not allowed, you must put the audio equipment between the speakers, and of course, the sound rack with a strong shock absorption effect must be used. But don’t forget that the vibration of the audio equipment is not only from the ground or audio rack, but also from the air, the vibration from the air cannot be eliminated with the audio rack, so some presses to absorb vibration or change the resonance frequency on the equipment. Sound small props. At present, there are two types of audio racks on the market, and some are made of expensive composite materials. Each material will have its own resonance frequency. This is unavoidable, but only where the resonance frequency falls. In terms of audio, the resonance frequency of audio rack materials is best to fall below 20Hz or more than 20kh, so that it will not affect listening to music. The question is, where can users know the resonance frequency of these materials? The factory does not provide relevant information. Generally speaking, the resonance frequency of metal materials is relatively high, the resonance frequency of wood is relatively low, and composite materials or carbon fibers are less likely to start resonance. The heavier the ability of audio racks, the better.
Some people think that the sound of wooden sound racks is better, which is caused by the resonance frequency of the audio rack. Some people recognize that the metal sounds are more nice, which is related to the makeup length of the entire audio system (including listening space). In fact, we can only make a simple judgment from the sound racks, and there is any connection between the inheritance and the pillar to make a simple judgment. In the end, we must really use it. How to arrange the audio room how many people think of the arrangement of the audio room, they will feel that they must be decorated. In fact, as an interior designer said: “The highest indoor design is to move the indoor furniture, just empty the nothing.” The layout of the home audio room is the same. The wall is knocked off, or the ceiling is weird. After all, if the space of the home can be used flexibly, the sound room in the home is arranged in the simplest and efficient way. The audio room is processed in the space. Because the space is covered with furniture, we naturally care about the impact of furniture -to -sound sound.
The first is to simply divide furniture into three categories: the first category is flexible furniture: cloth sofa, table towels, carpets, curtains. The second category is rigid furniture: coffee tables, dining tables, bookshelves without door. The third category is furniture with toughness: cabinets with doors and ceiling with splints. Why are they divided into these three categories? The reason is very simple, because these three furniture can play a regulatory role for the three frequency bands of the audio system. Once you understand the characteristics and processing methods of each band for further, then you can be fully able to fully be fulfilled The original indoor furniture is used for tuning. If the furniture is rich enough, in fact, as long as they move them appropriately, they can arrange a horizontal audio room. If there is a conditional enthusiast, all the walls on both sides of the speaker are placed on the open -frame bookcase, and the books are full of books. The sound field is clearer and better positioning. Principles of tuning need to explain the sound characteristics of high, medium and low -frequency bands before tuning: first of all, hightones, the frequency of treble is about 2kHz ~ 20KHz. What is straightforward, what is direct? It is like a ball straight forward. When encountering obstacles, reflection occurs, especially when it encounters glass, cement walls, etc. The energy of reflection is quite strong. As the frequency increases, the better the absorption, so the first type of furniture can be used to absorb high frequency bands.
The second is the middle sound, the frequency of the middle sound is about 500Hz ~ 2kHz. This frequency is a variety of instruments, and the most frequent part of the human voice is also very important. Solid, otherwise the sound will sound empty lack of real sense. Because the wavelength is longer than the high frequency, it will not be absorbed by the first type of furniture. Therefore, the focus of treatment should be transferred from absorption to diffusion. The most important thing is to spread the sound of this band. The wavelength of Zhongyin is from about 10cm to 60cm, so almost all furniture can have a diffusion effect. Therefore, the second type of furniture can be used as the heavy responsibility of diffusion Zhongyin.
Finally, the bass, the frequency of the bass is from 20Hz ~ 500Hz. In this frequency, it is part of the most headache. Even a professional audio room, I am afraid that there can be very few that can process this frequency band. Due to the long wavelength, there is no way for the first and second types of furniture. The only thing that is more feasible is to use some materials that will resonate, consume its energy through the resonance of the material, and the wood is the ideal tone tuning. Materials, so the third type of furniture can be effectively handled by the bass segment. The highlight of the audio room is to deal with the resident waves. The “resident wave” is the wave interference generated by the sound waves on the back and forth of the two -tonged wall, causing the enhancement or depression of a certain band. This situation is the most difficult to deal with in the low frequency band. For example, there is a strong energy. It is easy to mistakenly think that the low -frequency of the audio system is sufficient, but if you listen carefully, you will find that the sound is unclear. Do not use a square room or change the speakers.
