How I'd go after that is with an audio editing program
like Adobe Audition 1.5. (I've read many bad reviews
of version 2.0.)
First you open the audio file then normalize it, which
is under the effects menu.
Then you find a spot where there's nobody talking,
just the noise. Select it and use the noise reduction
to get rid of 90 to 95% and set it to leave only
noise.
Apply that noise reduction to the entire audio file so
you're left with just noise, then invert it and copy
to clipboard.
Undo the invert and noise reduction then use Mix
Paste.
This is pretty much what noise cancelling headphones
do, except they do it in real time. This trick will
work in any audio editing app with noise reduction,
invert and mix paste capability.
You'll most likely want to clip out the noisy bits and
only do the noise reduction where you absolutely have to.
