Unless just about everything I have run into on the subject is somehow wrong or doesnt bear on pianostrings, which given Conklins work seems highly unlikely. But this fact is apparently independant of what level of amplitude of these gets past the termination points. Another interesting point I have run across has something to do with the termination for the speaking length being on a "node" relative to the total length. Havent quite figured out what that is about yet, but I will look into it when I get my own experiment up and running. -- Richard Brekne RPT, N.P.T.F. Bergen, Norway mailto:rbrekne@broadpark.no
