When I was in the conference room building business, for sound
absorbtion/cancelling we used have foam rubber panels whose surface was made up
of rows of alternating cones and depressions. It looked very much like the kind
of foam rubber that is used to ship circuit boards (hard to describe - lots of
bumps and dimples that broke up the sound waves). If you could find a packaging
supply place, that might be an inexpensive source of sheet material to line the
closet walls. As far as ventilation, I suggest a louvered opening at the bottom
of the door, about 2 square feet, and an exhaust fan vent to the outside or the
attic. If you climate allows it, you could have your intake directly from the
outside.
An extra layer of sheet rock will also help to keep the sound down also, as
suggested. Also something under the compressor feet to absorb the sound and
vibrations would be a big help.
