Listening analyzes periodic sound into integer-multiple sine components
Evidence
Acoustically, a note perceived to have a distinct pitch contains frequency components that are integer multiples of f0 usually known as “harmonics.” Each harmonic is a sine wave, and since the hearing system analyzes sounds in terms of their frequency components, it turns out to be highly instructive, in terms of understanding how to analyze and synthesize periodic sounds, as well as being central to the development of Western musical harmony, to consider the musical relationship between the individual harmonics themselves. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 800
