Dear Paul, Using repeated gaussian noises as stimuli, Warren has described the perceptual characteristics of various repetition rates. While repetition can be heard down to about 0.5 Hz, pitch was absent below 20 Hz. It is noted that these boundaries are not discrete transitions. The repeated frozen noise segments were intended to be 'generic' or 'model' stimuli capable of revealing general properties of pitch perception, and lacking additional properties which may affect the pitch of other stimuli. see R.M. Warren's book on Auditory Perception (1999, Cambridge Press) and references there. -Eric At 01:15 PM 4/26/00 -0700, you wrote: >Below a certain frequency, periodic sounds are no longer perceived as having pitch; instead, they have a rough or pulsating quality (these are probably not the right words). But where exactly is this lower boundary for pitch perception, and on what signal qualities (besides frequency) does it depend? I'm guessing the threshold for simple tones is about 25 Hz, but maybe it's different for complex tones? In any case, it would be nice to know what the research literature has to say. > >I've looked in a few standard reference books (Moore, Yost & Nielsen, Handel), and searched PsychINFO, but have had no luck -- possibly because I don't know the proper keyword. > >Paul von Hippel -- Eric W.
