However, in audio technology it contains three aspects: (1) the pitch of the sound, that is, the intensity and amplitude of the audio; (2) the pitch of the sound, that is, the frequency of the audio Or the number of changes per second; (3) The timbre of the sound, that is, audio overtone or harmonic components. To judge the sound quality of an audio product, it is mainly to measure whether the above three aspects of the sound reach a certain level. It can be seen from the following aspects Look at the audio quality:

　　1. Clarity. The beautiful sound quality is very clear, with good transparency, and every word can be heard clearly.

　　2. Fullness. The mid and bass are adequate, the treble is moderate, warm, comfortable, and flexible. If the reverberation time is short, especially the reverberation time of the low frequency band is shorter than the mid frequency band, its fullness will not be too good; the output frequency characteristic of the audio system is poor, and the mid-bass is lacking, so the sound will appear dry Weakness, there is no fullness.

The consistency of the left and right channels of the stereo is good, and the sound image is normal. If the sound image is sometimes offset and not coordinated enough, it is not good sound quality.
