The speaker system should be nice, the most important thing is the location: the relationship between the space, the speaker position, and the listener is very important. Environmental factors are one of the important aspects of two-channel, 5.1 surround, Auro 3D, and Atmos surround sound. No matter which one you choose, you can expect a good sound. The audio manufacturer's advertisement always says: "We must faithfully restore the record" or "absolute original sound reproduction". This is also the goal that every enthusiast wants, so it will make people have the kind I bought this pair of speakers. The living room or the audio-visual room will immediately get the effect. For us, the sound should be as close as possible to the sound effect heard in the studio. There are several points to be made: sound placement, spatial measurement and correction. (Why don't you say the tone, because the tone color will vary with the device, the wire, and even the power supply, and the difference. The preference of the tone is a matter of personal preference. The tone is strictly speaking, there is still a standard. The way to follow.) Return to the source of record production: recording studio Why is this important? Because every album you listen to is composed and mastering in one or more designed and controlled environments. Each link is a combination of measurement, calculation and sound aesthetics. So, how can the space environment in the home try to reach an environment like this? Then let's briefly talk about the speakers and space. Positioning and space measurement This must be said first: "The speaker position is in a standard format." Although the above picture is the setting of Auro 9.1, there are still traces to follow. Assume that the center of the circle is the best listening position, and the angles of the left and right channels are as close as possible to the listener's 30 degrees. If there is a center channel, it is of course right ahead! The distance between the person and the horn is less than 1 meter. When extended to 5.1, the angle between the left rear and the right rear is 110 degrees, and then the configuration is advanced to Auro 3D. This is not a casual statement, but is developed by the ITU (International Telecommunication Unit) organization (ITU-RBS.775-3). What is the best distance between the left and right speakers? The ideal situation is: try to be between 2 and 3 m, and the distance between the listeners can be "horn spacing x 2" or "horn spacing x 1.7" (ITU-R BS.1116-1). In addition, the recommendation of Near-Field Monitors is to listen to the speaker size. The recommended distance is 0.7 ~ 2.3 meters. Understand the definition of the speaker placement, and then the measurement. Spatial measurement The best situation is: if there is a new home, let the professional acoustic design engineering company cooperate with the designer or decorating company to directly design the living room into a special audio-visual space. If not, then measurement is important, and it requires experienced engineers or audio companies with measurement technology to check. Instrument and human ear: The instrument is not biased for sound measurement. Want to create an environment that controls sound in the existing space, it must be matched by the instrument and the human ear. After the measurement, you can find out which frequencies in your space are particularly prominent or depressed through the instrument. The human ear is important, but the human ear is not credible. why? Because the human ear recognizes the sound differently because of different physical conditions. For example, if you are sick with you today, your ears may not be able to easily identify which frequency band has a problem, or if you put your ear together, you will ring your hand from time to time... etc. These conditions will affect; whether it is gold or not Physical factors can still affect interpretation. After the measurement, the instrument will tell you the current status of the space. It may be too much after 200Hz, causing the room to sound loud or the music has no layer or 400Hz ~ 700Hz. There are many depressions that cause many sounds to sound less meat. The 1000Hz and 5000Hz are too prominent, causing the sound to be too bright, sharp, thin, etc. . It's possible, even without so many problems, that you can have a very good listening environment with a simple process. Ok, since the instrument tells you what problems are in this space, it will be solved. There are many ways to solve it. Many people will tell you how to place things in your existing space, to make the surface of the space appear irregular, or to place long-haired carpets to absorb sounds, etc. This is a bit helpful, but it's very likely that there is no help for visual beauty. At this time, the tuning device is a very useful thing. Some tuning equipment on the market is both aesthetic and functional. Although the price is not very beautiful, it is a good solution compared to re-enacting space. Most of us use two channels to listen to music and watch movies. One thing that can be noticed is that the horn has a mystery behind the horn except that the angle is the angle of 30 degrees left and right. The wall behind the horn can be made into a dense thick wall that is also 30 degrees. The sound absorbing and diffusing tuning sound can be used on the left and right sides, and the diffusing film can be added to the wall behind it. The number of furnishings must be measured while being placed on the side to know what extent to be acceptable. In addition, the professional monitoring environment really needs to achieve a beautiful flat frequency curve; general Hi-Fi low-frequency can be more than 3db is not too much. I want to buy a sound, but the space really can't be adjusted like this? Not everyone's home is ready to be refurbished or a blank space can be played. Audio company Linn has the function of Space Opitmisation, which can calculate the frequency curve by using the software in Linn DS Player to calculate the frequency curve according to the parameters of the space. It can be compared with the frequency curve obtained by the measuring instrument, and then in the software of Linn. Make detailed adjustments to the space. France's Trinnov Audio also has such a calibration system for multi-channel systems. The professional SAM system of the professional monitor speaker brand Genelec also has a measurement and correction system for the space. Through the professional software and hardware devices of these professional manufacturers, you can make a profile for your own space, and you can face the problem and solve the problem. If you are using a desktop speaker, try to avoid the wall too close, which is more than 5 cm and less than 60 cm. The angle and height of the horn are also as close as possible to the angle of 30 degrees to the left and right, and the treble monomer is as high as possible with the ear. I hope that this information will help you a bit. After all, listening to happiness is just two different things. Well said, some people have more demand for low-frequency, even if their space low-frequency is too high, they also feel good, because that is what he wants. In the same way, you can put those who like the mid-range and mid-high frequency bands, but they will feel that the low frequency is very annoying, and the low-frequency enthusiasts will feel that this is too bright and too jump. This is all about the preferences, cognition, and choice of sound. For those who want to listen for a long time, adjust the listening space slowly, or choose a sound system that can be adjusted and adapted to the environment.
