foam baffles

[Paul McCloud]

Years ago, I ordered a large sheet of acoustic foam from a local musician's supply  co.  The cost was about $110, and was enough to do two pianos with extra to spare.  Cut with an electric knife.  You can save some money, but you'll spend some time cutting and fitting the pieces.  The reduction was less than spectacular, but did work as good as Edwards.  To eliminate more sound, there needs to be some heavy insulation sandwiched inbetween.  I'd say a 25% reduction would be expected with the foam underneath, again as much on top.  YMMV.

Tom, ditto John's note. You can find varying thicknesses of foam at Home Depot quite cheap, and that's what we did to create the six studios here at the school. Same stuff, comes in easily handled sheets, and easy to cut and shape.

Tom, 


My experience is just with one piano. I ordered a top cover and bottom pre-cut foam from Edwards. If I had to do this over again, I'd buy a sheet or two of acoustic foam, and cut it to fit the piano.  That's all the bottom foam is from Edwards.  And the top piece has the same type foam with a cloth cover.  Granted, it's custom-fit to the piano, which is nice.  But quite expensive.  Seems like the pre-cut foam was $110 (for a Yamaha G1). Three or four pieces that wedge in between the beams.  Easily done for less on the bottom pieces with a sheet of foam and a sharp knife.  


That, along with voicing, made the customer very happy.


I remember from my Googling "acoustic foam" after that experience, that there are different grades of the stuff.  More dense, more reduction.

List,
 Problem :
Apartment dwelling piano performance major with a small grand is getting complaints from the neighbors .
I can't find any info on sound reduction materials designed for the piano.
Did Edwards have some products ?
Thanks.
