The sound quality of sound is closely related to many factors. For example, the quality of audio (source), MP3 music files with low bit rate and music CD contrast, in the details of the music will be more monotonous, lack of some details of the music, the natural sound quality will be greatly reduced.
DMJ Audio teaches you a few simple ways to identify sound quality:
1, clarity. The wonderful sound quality is very clear, the transparency is good, and every word can be heard clearly.
2, fullness. Medium and low bass, moderate treble, warm, comfortable and flexible. If the reverberation time is short, especially the reverberation time of the low frequency band is shorter than the middle frequency band, its fullness will not be too good; the output frequency characteristics of the audio system are poor, and the middle and low sounds are lacking, so the sound will appear dry. Powerless, but also not full.
3, intimacy. It is the kind of expressiveness that people usually say, that is, there is a sense of communication and confession in the voice heard. The general or very poor sound quality is not experienced, it will make you feel urgent and far away.
4, a sense of balance. Refers to the left and right speakers, the proportional coordination of the output power between the main and auxiliary speakers and the correct phase. The stereo left and right channels have good consistency and the sound image is normal. If the sound image is sometimes offset and not coordinated enough, it is not a good sound quality.
5. Environmental sense. The sound has a good sense of space, and the whole gives a realistic feeling. It is most appropriate to use immersiveness to describe good sound quality.
6, loudness. In terms of loudness, good sound quality sounds appropriate and comfortable.
When you turn on the sound to listen to music, the first sound is good, the sound is powerful, especially the mid-high frequency is bright and moving, the low frequency is also satisfactory. But I feel uncomfortable after listening for a while, especially "tired" people, have to shut down Going away. This kind of speaker that makes people feel "tired" is not a guest, because it makes people feel "very noisy" and annoyed. The speaker "noisy" indicates that the box has a large distortion and is not resistant. Definitely not a good speaker.
Listening to the good quality speakers, it seems that the Chen Huadiao daughter who has been deeply buried for 30 years is so sweet and refreshing, and has a long aftertaste. The kind of "sweet" and "warm" music will make You forget the time, space, and even forget your own existence and revel in the ocean of music, no matter how long you listen, you won't get bored.
Good speaker distortion is extremely low. Therefore, no matter the volume, it will make you sound very ear. Even if the volume is turned to full power, the speaker will be shocking, and the low frequency rolling like a midsummer will only make you feel close to nature. Even the horrible shock, but will never give you a sound that will make you escape.
Generally speaking, the sound is thin, the sound is cold and hard, and the speed is too fast. The speakers are not resistant. It is certain that they are all sound thin, the sound processing is weak, the frequency divider is too simple, and the speaker is lower. The result is naturally not a good speaker. The good speaker is very resistant, it not only keeps the guests, but the longer the listening time, the more familiar it is, the more the sound is in the ear.
Sound discrimination sound quality six factors
The quality of sound 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.
