Disklavier

We had a similar problem (from my wife's point of view).

Carol Beigel recommended to install the sound absorbing foam, it 
worked fine. (Great advice, thanks Carol)

Now we both listen the piano and even answer the phone without 
stopping the piano "performances", the sound is still great (but not 
loud).

I brought the bare foam sheets from:

You have to cut them to size, but compare the pricing!
