I have in my care an Estonia concert grand about 6 years old.  It has a 
Renner action.  The jacks make quite a slapping sound when they hit 
their rest cushions.  The institution has not voiced any complaint yet, 
but it sure bothers me when I service it.  Looking at the cushions, they 
seem fine - neither too thin nor  what I would call too firm.  Is this a 
common condition?   Will replacing the felt  punchings make a real 
difference?
