Hey guys I don't want to hijack this thread, however I remember I had read something on another forum about a very similar topic and a member said something that goes in counter of
The member is LPFR and he said
I myself do not understand most of the subject (so I'm here to give insights using other people since I'm not competent). The thread is http://forums.futura-sciences.com/physique/480015-serie-de-fourier-perception-auditive.html.atyy said:Anyway, the ear performs a Fourier decomposition of the incoming sound into its component frequencies.

which would be something likePour finir, l'oreille humaine n'est pas sensible à la phase des signaux mais uniquement à la puissance. Je me souviens qu'il a fallu faire la manip avec deux synthétiseurs (plus oscillo plus haut-parleur) pour convaincre un collègue que l'oreille humaine ne calculait pas ni la transformée ni la série de Fourier.
There are some links in the mentioned thread (some of them in English). I'm not sure LPFR is right though but from the quality of all his posts and his experience, if he's wrong on this then there must be a "nasty" reason.To finish, the human ear is nonsensitive to the phase of signals but is sensitive only to the power. I remember that we had to do the experiment with 2 synthesizers (aside with an oscilloscope and a speaker) to convince a colleague that the human ear does not calculate the Fourier transform nor the Fourier series.
