LOL...TRIPPLE post!
I have already asked an accoustical engineer what to use. He said to use
Owens Corning Fiberglass Board #703 Here is the Owens Corning product page for it:
http://www.owenscorning.com/comminsu...ct=1&System-83 The thinnest that stuff comes is 1" (up to as thick as 4"). The accoustical engineer said the thicker the better as the thin stuff doesnt absorb the low frequencies very well. However I haven't been able to find this stuff anywhere. I even called Owens Corning directly (1-800-GET-PINK) and asked for dealers which sell their product. All they could recommend was Home Depot bascially. I went to Home Depot and asked but the guy I talked to their didnt have any idea what I was talking about.
The engineer also recommended using
Mason NDA Mounts to isolate the pump. Here is the product page for these things:
