Time‐Frequency Analysis in the Hearing Process

The hypothesis that a temporal waveform analysis is performed along the basilar membrane is considered and proved wrong, on the basis of a comparison between the uncertainty principle in Fourier analysis and the time‐frequency relations in the cochlea, obtainable from experimental data. A suggestion is introduced in the conclusions for an appropriate electrical model of the cochlea, which could prove useful for both Fourier and waveform analyses of speech.
