Pyschoaccoustics: noise vs. sound vs. music

 

Psychoaccoustics is the application of physics principles to the study of sound.  KCM will use these principles to understand the underlying structure of music and our perception of it.  So while psychoaccoustics can’t tell us why there is a tendancy to resolve from the 5th degree to the 1st degree of the major scale, it will help us understand why the Tritone and b9 sound so “crunchy”.

Some of the most important concepts of psychoaccoustics used in KCM include:
-Cochlear Spectral Decomposition
Critical Bandwidth
Linear Roughness vs. Non-Linear Beats


Wikipedia on psychoaccoustics

Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound (including speech and music). It can be further categorized as a branch of psychophysics.”


brief summary then describe psychoaccoustics contribution to KCM.
In particular,

Critical bands.

Roughness and beats
