John, Years ago I had to significantly reduce the volume of a piano without voicing. The piano tone was fine, but the owner had tinnitus, so she couldn't bear the sound. She was going to return it to the dealer - so we had to do the job in a way that was reversible. I bought a 2-inch foam mattress at an Army-Navy store and cut it up to fit into the bottom of the piano. The cost was minimal, and one mattress yielded more than enough foam to do the job. The reduction in volume was significant - the client kept the piano and everyone was happy. Good thing - it was a new Steinway L... I am not sure that so called "acoustic foam" is worth the expense. From what I read on the results of a "Google" search the concerns being addressed are mostly architectural - fire resistance and appearance. These are not considerations when installing foam in a piano - it's out of sight, and the piano itself is not fire-resistant... So next time, try the simple foam mattress - it will do the job. Or give your client the choice - are they willing to pay the extra fifty bucks for pretty, fire-resistant foam? Israel Stein
