Hi David, I once had the experience of working on a Yamaha C7 for a concert that just didn't "cut the mustard". I finally got underneath it and sure enough the movers had wedged some thin rubber strips between the beams and the soundboard. The strips appeared to have been cut from tire inner tubes--perhaps one could simply use an old inner tube for a bike? It might be worth consideration if you are planning on reducing sound and using a DC system. You don't mention if this is an "apartment" situation. If it is a lot of sound energy will be going down the legs into the floor. Isolate them by using a "sandwich" made from tempered auto glass, four "dots" of carpet to provide an "air break" and another layer of glass. I discovered this in my home when I was trying to isolate two studios on the same floor. The piano (a C7 again as it happens) could not be heard thru the walls which were specially built--but the floor joists carried enough energy that the piano could be heard. The "sandwich" describe above dropped the amount of sound down to the point where one *really* had to be totally quiet to hear the piano. It's important to use tempered auto glass as it is really three layers glass/plastic/glass. As the sound waves get refracted and attenuated by to some extent. It was commonly in use in sound studios at the time for windows. This was about 1976 so the state of the art may have changed quite dramatically since then.
