Subject: Re: Minimum duration required in a sinusoid to hear pitch From: Massimo Grassi <massimo.grassi@xxxxxxxx> Date: Wed, 15 Mar 2006 10:11:34 +0100> I would like to know if there exists some research done about the > minimum duration that a sinusoid has to have in order to hear pitch. > Any reference to related literature will be highly appreciated. as far as I know there are two works but the timbre was complex: Robinson, K.L. and Patterson, R.D. (1995) "The duration required to identify the instrument, the octave, or the pitch-chroma of a musical note," Music Perception 13, 1-15. Robinson, K.L. and Patterson, R.D. (1995) "The stimulus duration required to identify vowels, their octave, and their pitch-chroma," J. Acoust. Soc. Am. 98, 1858-1865. The interesting result is that, when compared to vision, the auditory system extracts first complex features (i.e. timbre) and later simple features (i.e. octave and chroma). It seems that the visual system operates in the opposite way (e.g. Marr, 1982): first simple features then complex features.
