We had a box like that around our water pump at Lake Winnepesaukee
when I was a wee lad.  We ran the pump a couple hours every few days
to fill up the stock tank for our gravity-feed water system.  The box
made a considerable difference.

When you're shooting for silence, though, it gets harder; because
every time you remove 90% of the noise energy, the perceived noise
drops by half.

I have heard that some of the little Hondas -- a 350-watter in
particular, I think -- have extra quieting and do a pretty good job
with it.  Not silent, but pretty quiet.  Never heard one, so I don't
really know what that means in practice.
