West Marine lists several sound deadening kits in foil/foam rolls that might
work well for you. As for the bolted down vibrating stuff, this is often handled
by mounting pads that allow more flex an movement (assuming you have feet on the
generator). At my last job we used some energy absorbing pads strategically
placed on, around, and under certain parts of a very noisy piece of lab
equipment that worked amazingly well. I think the brand was ISO, but I am not
sure. Do a search under deadening, sound absorption, ISO, and whatever else you
can think of, You may be able to get a sample that would be enough to do the
I'll look through my files and see what I come up with.
