I'll compile the list and pass it by here in a few weeks. Very good stuff! Patrick, I was there and that's something that would be interesting. Will do! \ Jim Busby -----Original Message----- From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of James Patrick Draine Sent: Friday, June 18, 2010 6:06 PM To: caut at ptg.org Subject: Re: [CAUT] Anechoic chamber - experiments Hi Jim, I'd be most interested in studies of the Jorgensen effect: unisons which go flat as the 2nd and 3rd strings are tuned to the first string. Roger Jolly wrote his own observations and measurements of this on pianotech, a long time ago. Sanderson co-taught a class with Jorgensen investigating the effect, but I skipped the class(es). I think it was either at Reno or Chicago (2001 or 2002). I don't believe Sanderson's findings were ever published.
