A decibel is the tenth part of a bel (B), a unit named after Graham Bell, the inventor of the telephone. Its logarithmic scale is adequate to represent the auditory spectrum of the human being.The thing to keep in mind is that in digital audio, going from 0dB generates saturation since that is the maximum limit and the wave is quadratized. Which means that it loses its natural curvature, to take the form of "a step" which takes away quality. Exactly as an image when it is pixelated.http://mp4gain.com/mp4gain/wp-content/uploads/2019/09/decibel-level-300x150.jpg
