I was at an event where we had to run one of those noisy things.  I found
that folding table laid over on it's side made a wall between the genny and
us that took a lot of the "bite" out of the noise.  Higher & denser
material (plywood / particle board) would be more effective.  A heavy
blanket or rug on the genny side would help even more.  The barrier can be
a couple feet away from the genny.  It does have to be high enough to block
the "line of site" between the genny and the ears that don't want to hear it.
