Hearing’s salient spectral features can be matched by adjustable Fourier analysis
Evidence
Another strategy makes use of those important features that are selected by our hearing system. Spectral pitch, for example, plays an important role in characterizing music and speech. There are many spectral pitches in musical sounds, some of which are very dominant, others that are of less importance and still others that can almost be ignored. The physical equivalent of spectral pitch percepts are “partial tones”, which can be extracted by a hearing-equivalent spectrum analysis. Such analysis is performed by a modified Fourier transformation which allows adjustment of analysis parameters with regard to the frequency and temporal resolution of the human ear. — Professor Dr.-Ing.
