How to judge the sound quality of the speaker
The content reflected by the sound is often clear, specific and objective, but the sound quality and timbre are extremely abstract, subjective and inconvenient to communicate. To do a good job in evaluating sound quality, you need to agree, summarize, and sublimate. Just as the sense of taste is established by convention, everyone says that sugar is sweet, so people call the feeling of eating sugar "sweet", and then encounter this kind of taste, even if it is not sugar, everyone said that it is sweet.
There are many terms for sound quality evaluation, and it is also complicated in richness. It is necessary to grasp the main and key to be standardized to facilitate our performance and communication.
1. The sound from the clear and muddy sound system should make people feel clear, the frequency response should be wide and uniform, especially the high and middle frequencies have density, and the reverberation is appropriate, which can better distinguish the tone and position of the instrument, otherwise it is called muddy .
2. Roundness and hair Roundness refers to the sound without distortion, especially the sound with very little distortion in the middle and high frequencies. This kind of sound feels pleasant and pleasant. The bass is not turbid, the midrange is not stiff, and the treble is not ears. The hair is opposite to the roundness, the main feeling is that the sound is rough and there is audible distortion. If there is 5% distortion in the sound, the average person will feel hairy, and professionals can listen to 3%.
3. The plump and shrivelled sound is thick, loud, and has a good sense of mid- and high-frequency volume, and a sufficient reverberation. The transient response is called plump, otherwise it is shrivelled.
4. Brightness and grayness Brightness means that on the basis of the balance of high, middle and bass in the entire sound range, the middle and high frequencies are slightly prominent, and there are rich harmonics, moderate reverberation and low distortion. Grayness refers to a serious lack of mid-to-high treble, bass relaxation, and poor resolution.
5. Broad and thin sound The frequency response of the sound is good, the treble is bright, the bass is sufficient, and the thin sound often lacks bass or treble.
6. Dry and wet mainly refers to the reverberation effect. The short reverberation time and the lack of depth show dryness. The reverberation is excessive and appears wet. The dryness and wetness of the sound are sometimes determined by the software, and can also be caused by the listening environment.
7. Liveness The sound is bright and well diffused, with a certain amount of reverberation, especially in the 800 ~ 5000Hz, the sound is relatively dense, and the effect closest to the concert hall is called good liveness.
