What is the concept of sound quality called true sound reproduction?

- Feb 27, 2020-

How do we understand and judge whether a set of audio meets the sound quality requirements, it becomes necessary before tuning. The so-called sound quality includes these four aspects: loudness, tone frequency, tone color, and sound field. Let's briefly analyze below ↓

1) Loudness: it can be understood as the volume, which is related to the amplitude of the sound vibration and the propagation distance.

2) Tone frequency: the frequency can be understood as the number of vibrations per second of a single tone. The frequency range of human ear hearing is 20 ~ 20,000Hz (K = 1000 often seen), which is what we often say treble, midrange and bass. ,very low voice.

3) Tone color: Through the waveform representation, the waveform contains basic and overtones in a frequency band, enabling us to distinguish different people and instruments.
