I found that heavy foam carpet underlay is a better box liner, easy to find (you
can find huge unused chunks (rollends) in dumpsters behind carpet stores) and
it's easy to glue into place in layers. I have 4 layers in the 'box' under my
work bench and my huge noisy Shopvac is very quiet, as is my air compressor. My
AC sits on top of 3 layers of carpet underlay as well.

Thanks for the suggestion of using 4 layers of carpet underlayment. It
should be easier-to-get and cheaper than special sound-dampening foam.
I will keep this in mind.
