How to buy professional audio according to the sound quality?
The stage performance of the 1. sound stage
The sense of space of the sound field is closely related to the positioning of the horn: the height, width and depth of the three-dimensional sound field extend to the wall, and the height, width and depth will form the shape of front convex and back concave or relatively flat or square or rectangular or elliptical, which is the overall sense of space of the sound field extending up and down, left and right back. This sound field shape is the sense of space of various shapes. The best sense of titanium sound film is to diffuse the whole listening room, the relaxed and transparent sound field space feeling of huge and boundless feeling in all directions, even the feeling of penetrating the surrounding walls, basically, in addition to good equipment, there must be appropriate space size, too small space is more difficult to achieve perfect space feeling.
The level and positioning sense of musical instruments and human voices in the sound field. The level refers to the stereoscopic nature of musical instruments and other sound-producing bodies in the sound field and the change of depth or distance. The positioning sense refers to the stereoscopic left, right and up and down positions of the sound-producing body. If the sound system equipment is not good enough or the sound box is not well positioned, you will not hear the sense of body, especially the sense of body with depth. However, the overall sound stage should be formed on the stage behind the left and right loudspeakers. If the sound rushes forward, it is wrong, especially when the low-frequency performance rushes forward, it feels like pounding the chest. At first, it is thought that the strength of large volume feels enjoyable, but it will be very uncomfortable after listening for a long time, which is incorrect.
2. the density and weight of sound
The density and weight of the sound in the shape of the overall sound field are related to the amount of details of the sound and the stability of the sound field. The stability of the sound field is high and the weight is strong, which is also the performance of the accurate positioning of the instrument and the non-drift of the body. The high density of sound is the expression of more details and full sound feeling. The higher the density, the better the feeling of encircling or embracing the ears or body, the better it will feel like experiencing the scene.
Transparency and clarity of 3. sound
The transparency of the sound field is related to the sound itself and the cleanliness of the background, and is related to the contrast degree of S N/N in terms of instrument measurement. Transparency is good, space is good, clarity must be good, sound mixing, sound paste such as interlayer fog or hazy yarn, sound field must be relatively flat without depth, audio and video is large or even paste into a ball, titanium film common bass hypertrophy is an example, or bass paste into a ball, some people think that it is low frequency thick and powerful and self-rejoicing, this is actually wrong, listen to live music concerts when comparable to know.
The clarity is often confused with the phenomenon that the medium and high volume is more bright. The medium and high sounds are brighter and brighter, and the overall low frequency proportion is reduced. The hearing feeling is unnatural. If the lip and tooth sounds are more harsh and uncomfortable at the same time. It is difficult to do a good job of low frequency definition, which can be determined from the identification degree of microtremor of large drum skin tail rhyme or Double Bass string.
Equilibrium of 4. Senior high school low frequency band
Only when the high, medium and low frequency bands of the sound are balanced can the sound be pleasing to the ear. If it is too bright (too much high frequency), especially if the lip and tooth sounds are too much, it will not be vivid. If it is too dark (too little high frequency), it will not be vivid. If it is too low, it will cover the theme. If it is short of things and integrity, or if the medium frequency is too high, it will not thick enough, it will lack warm and rich, it will become dry.
5. the beauty of sound quality
The requirements are not only pleasing to the ear, but the music can also infect the transmission of all emotions, or the poetic and picturesque softness or surging heroic feelings, while the poor sound quality produces the feeling of raw, cold, hard, thin and thin.
6. sound resolution and detail
With strong analytical power, there can be more details. The general sound system is the most difficult to do with low-frequency analytical power. Only with more details can we hear the micro-vibration (or rosin flavor) of the dense string wiping of strings and the wood flavor of the instant hit of the piano hammer, as well as the extension of the final rhyme and the resonance of the steel string with the piano cavity and the piano reflector, as well as the emotional expression of the weak breath of the human voice, low frequencies such as instantaneous tension and extended tail rhyme when the drumhead is hit by a mallet.
Cohesion and Body Sense of 7. Sound
The cohesion and form sense of sound refer to the well-focused, non-dizzy musical instrument or mouth shape or condensed drum sound, as well as the size ratio of human voice and musical instrument. This item is related to the phase distortion of equipment and the diffusion angle and reaction speed of the horn, and also has a great relationship with the adjustment of the toe-in angle of the sound box. The system that is not delicate enough has halo, the shape is too large and out of proportion, and the cohesion and the sense of proportion, the music stage is not shaped or shaped incomplete, unable to achieve the natural huge stage effect.
8. have a lively sense of vitality
The contrast of the sound intensity of playing (singing) tracks is the dynamic size, which directly shows the dynamic degree of the sound on the scene. The dynamic of titanium sound film is as big as the recording scene, which is the lively feeling of vitality. After the dynamic is compressed, the sound will become dull and not vivid. The reaction speed of the general sound is related to the speaker monomer and the amplifier. If there is no details and dynamic, the sound will become dull and boring, there are few levels, weak contrast, and the sound performance is very flat and not vivid. It can only be listened to like background music but not really appreciated. The dynamic is large, the details are many, and the sound is natural and sweet. It is the lively feeling of vitality that can convey the true feeling of music "moving.
