First try using the sostenuto to isolate which section of the dampers is
actually making the noise (requires depressing the keys with the length =
of
the forearm). =20

Yes. I have remedied this problem on several older Steinways by simply
replacing the bass dampers. It's a relatively quick way to effect a
significant reduction in pedaling noise in those cases where the =
customer is
reluctant to spend the money on a more complete job.

1950-ish Baldwin L grand, all original. Raise dampers with pedal and =
then
release pedal. Dampers make quite an audible thump. Remove action and
manually lift a dozen or so dampers and you get a similar thump - it is
especially prominent with the bicords - very little noise from the flat
dampers.

Is this nothing more than the sound that 55 year-old grand dampers make?
That is my strong suspicion.
