false beats from??

[Ric Brekne]

I think I remember something about Wograms article on this in his 
discussion about soundboard impedance, whether or not it was massy or 
springy at any given point that made me think along the lines of a cause 
for false beats.   Might be time to re-read that ...:)  again.

Cheers

What is it about soundboard design that influences the tendency for the
piano to develop false beats? Ron? Ron? Del? Anyone else?
