Subject: (Fwd) Re: place pitch and temporal pitch From: "Ward R.

Why should that necessarily be a restraint? I've heard 4KHz and 8KHz sinusoids and the 8KHz always sounds higher than the 4 KHz. It's not timbre--- because it's a different pitch. Place theories are incomplete as is a purely temporal theory. Seebeck would have loved you though. > On Friday, March 19, 2004 8:38 AM, Christian Kaernbach wrote: > > > Evidence for place pitch: A sinusoid of 5 kHz elicits undoubtedly > > a perception of pitch.
