You forgot one major step:  install a cooling fan so that the expensive
electronics inside (Eagles aren't dime-store items!) don't overheat.  And
then start all over again, because the $@#%@ fan is too noisy!

Seriously, this is a real and major problem, and by far the biggest headache
involved in noise shielding:  providing adequate cooling.  Fans are probably
causing a major fraction of the noise in the first place!
