Subject: Lower frequency limit for pitch perception From: Paul von Hippel -- Ohio State <pvh(at)CCRMA.STANFORD.EDU> Date: Wed, 26 Apr 2000 13:15:37 -0700Below 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.
