I know people who use Dynamat in their vehicles and it helps a 
lot.  I don't know a whole lot about it, but I figured I'd throw it 
out there.  <http://www.dynamat.com>www.dynamat.com  - you can 
probably pick some up at your local autoparts or car audio store.

good luck,
drake

      This was standard problem/issue in early wireless stations.

      Commonly, in the old days, the gap was enlosed for sound
      suppression, especially when high poweres were used.
      Sometimes 'in its own room'.

      A point to Ponder is that many sorts of foam are Highly
      Flammable.  (cf the Station Night Club fire.)  I'd be
      real careful, in picking.  Perhaps 'fiberglass insulation'?
