sound reduction

[John M. Formsma]

I don't think this has that feature, but I'll check. 
 
Thanks,

Please don't take the attached photo as a recommendation. While it might do
the job, I include it here just for laughs.
 
If the Disklavier is a MKIV you might try just putting it into "quiet" mode.
While the keys still move the piano itself is no longer actually playing and
is relying on midi playback through the speakers. Just turn down the volume
until it's quiet enough. But you probably already know this. 
 
Here's a bad idea! Why not try installing some kind of mute? Perhaps just
laying something like the keyboard cover felt that came with the piano
across the top of the strings would dampen it enough. True, it will sound
muffled and awful, but chances are that once you get the piano quiet enough
for their needs it's probably going to sound like that anyway. It's the
attack and those lovely upper partials reverberating around that big open
hard space that are making it too loud. If they won't compromise the space,
loss of dynamics and tone are probably inevitable

List,
 
I'm needing to further reduce the volume of a Yam G1 with a Disklavier. I've
installed a top foam pad and bottom acoustic foam baffles from Edwards
String Covers. The sound reduction has been quite noticeable, but is not
enough. The owners want to be able to have the piano play without drowning
out dinner conversation in an adjacent room. The piano is in a largish room
with hardwood floors throughout the house. The room is central to the house
and is open to the second floor. Not much for absorbing any sound in this
location, but that's what I'm working with.
 
What I'm considering doing is adding more acoustic foam to the bottom of the
piano as that seemed to be where most of the sound comes from, or at least
it's more noticeable by reflecting off the floor. There is room for another
4 inches of foam under the soundboard, and I suppose I could stuff it full
as necessary and cover it with a Dampp Chaser undercover if that would work.
???  The owners are not ready to put a rug under the piano, but might
consider that if nothing else will work. I saw something online
(International Piano Supply, I think) about neoprene caster cups. How much
would that help, if any?
 
I don't have any previous experience with acoustic foam and am learning as I
go. Anyone have experience with this kind of situation?  Any advice will be
appreciated.
 
Is there a better place to purchase the acoustic foam other than Edwards?
The pre-cut pieces are $110 wholesale, but it seems just as easy (and much
cheaper) to cut a piece that will fit into the various sections divided by
the beams. I've looked online at a few places, and have found sheets of foam
for various prices according to the sound reduction. Any good suppliers you
know of?
 
Thanks for any help.
