The sense that I got out of that was that a more rigid termination point on
the bridge allows more energy to stay in the strings, increasing sustain.
This would imply that some "energy" (in some form) passes through the
strings to the bridge.  I was wondering if the "before" and "after" graphs
of actual measurements would be useful to this discussion.  Do both theories
predict the observed results?  (Or do we need a better experiment?)

I also thought it was interesting how they described "mechanical energy"
being converted to "acoustical energy" at the bridge.  Are these terms
well-known?  I don't want to muddy the semantic waters.
