Psychoacoustic Model - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/psychoacoustic-model
Lossy audio compression transforms the signal into a frequency representation by employing psychoacoustic models which remove information from the signal that is not perceptible to human listeners (e.g., due to masking effects). Although lossy compression has different goals than feature extraction, features may benefit from the ...

https://www.techhive.com/article/601574/three-minute-tech-audio-compression.html
The basic principle of lossy audio compression is that it uses perceptual coding and psychoacoustic models to determine which sounds and frequencies humans can’t hear. While the difference in bit...
