Subject: Difference Tones From: "Dr. Michael Gordon" <mgordon(at)UTM.UTORONTO.CA> Date: Thu, 12 Sep 2002 11:05:36 -0400Dear List, A colleague of mine has been looking for information on 'difference tones'. Those are tones created by the interval between two wavelengths. If any of you know of references relating to difference tones or what sort of set-up would be conducive to hearing difference tones it would be greatly appreciated. Thanks, Mike -- Michael S.
