The sound quality is subjective and abstract, and the higher the degree of sound reduction, the better the sound quality. To put it simply, distinguishing the various instrument types in the music, the sounds of various instruments, and the sense of presence are closer to the true sound quality. The sound quality of sound is closely related to many factors. Let's talk about the six main points of evaluating sound quality:
First, the stage performance of the sound field
The spatial sense of the sound field is related to the horn position: the height, width and depth of the sound field extend to the wall. The height, width and depth will form a convex or concave shape or a relatively flat or square or rectangular or elliptical shape. The shape of the overall sound field is extended from top to bottom, left and right, and the shape of the sound field is the sense of space of various shapes. The best sense of space is the sound field that permeates the entire listening room and is easily and transparently surrounded by a huge sense of infinity. The sense of space, and even the feeling of penetrating the surrounding walls, basically has a proper space in addition to the equipment, and it is difficult to achieve a perfect sense of space in too small a space.
The level and orientation of the instruments and vocals in the sound field, the level refers to the three-dimensionality of the sounding body such as musical instruments in the sound field and the change of the depth or the distance. The sense of positioning refers to the left and right and the upper and lower sides of the sound field of the sound body. s position. The level and positioning are good, and various instruments and vocals have a three-dimensional body feeling. If the sound system equipment is not good enough or the speaker is not well placed, the body sense can not be heard, especially the depth of the body. The overall sound field should be formed on the rear stage of the left and right horns. If the sound is rushing forward, it will be wrong. Especially when the low-frequency performance is rushing, there is a feeling of slamming the chest. It is thought that it is a big volume of power, but it will be enjoyable for a long time. Very uncomfortable, it is not the correct performance.
Second, the transparency and clarity of the sound
The transparency of the sound field is related to the tone itself and the cleanness of the background, which is related to the degree of contrast of S+N/N. Good sense of transparency, good sense of space, clarity must be good, sound mixing, sound paste such as compartment fog or crepe, the sound field must be relatively flat without depth, large audio or even a paste, a common bass hypertrophy is an example Or, the bass is also a mess. Some people think that it is not good enough to be a low-frequency, powerful and self-satisfied. Listening to live music concerts can be compared.
The clarity is often confused with the phenomenon that the medium and high volume is more bright. The middle and high notes are brighter and more partial, and the overall low frequency ratio is reduced. The sense of hearing is unnatural, and if the lip sounds at the same time, it will be harsh. Low-frequency clarity is difficult to do, and can be determined from the degree of discrimination of the big drum skin rhyme or the double shock of the Double Bass string.
Third, the resolution and details of the sound
Strong resolution, more details can be more, the general sound system with the low-frequency resolution is the most difficult to do, the details can be heard the string of the micro-shock (or loose scent) and the sound of the piano hitting the wood And the extension of the tail rhyme and the resonance of the steel string with the piano cavity and the piano reflector, and the emotional expression of the weak voice of the human voice, the low frequency such as the instantaneous tension and the extension of the tail when the drum skin is beaten.
Fourth, the balance of high, medium and low frequency bands
The high, medium and low frequency of the sound can be balanced, too bright (high frequency too much), especially the lip tooth sound is more uncomfortable, too dark (high frequency too little) is not vivid, low frequency expansion (too much) will flood the theme The lack of low frequency will be like the lack of something in the lower plate, the lack of integrity, or the medium frequency is too thick, it lacks a warm and rich sweetness, and becomes dry.
Fifth. The cohesiveness and physical sense of sound
The cohesiveness and morphological sense of sound refers to a well-focused, non-vibrating instrument or mouth-shaped or condensed drum sound, as well as the size ratio of vocals and musical instruments. This and the phase distortion of the equipment and the horn diffusion angle and reaction speed Related to the speaker toe-in angle adjustment relationship is also very large, not delicate system has halo, the body is too large, disproportionate, cohesive and physical sense is not good, the music stage is not formed or incomplete formation, can not reach the natural huge stage effects.
Sixth, a lively sense of vitality
The intensity of the sound of the performance (singing) is the dynamic size. The direct performance is the degree of dynamic sound of the scene. The dynamic is as big as the recording scene. It is a lively and lively feeling. After the dynamic is compressed, the sound will become dull and unreal. The response speed of the sound is related to the speaker unit and the amplifier. If the details and dynamics are lacking, the sound will become dull and boring. At this time, the sound has no depth, less level, weak contrast, and the sound performance is very flat and not vivid. Listening to music like background music can't really be appreciated. It is dynamic, with lots of details, and the sound is naturally sweet. It is a lively and lively feeling that can convey the true feelings of the music.
