Thanks for your well thought out reply, Bob. I think I'm beginning to get the idea now. I've been doing a fair bit of reading today.
For anyone interested, a couple of links: -

There are a lot more links to related stuff at the bottom of those pages, too, for the diehards.... Steve

I seem to remember egg cartons, especially the the larger 12 x 12 squares bases (not the boxes with lids) being very effective as the sound passing through would bounce around owing to the angles of the cardboard domes.

We had to soundproof a room at work and called in the "experts". Without adding huge amounts of insulation, the most effective method involved the use of MASS in the form of lead sheeting, about 3mm thick in the walls and ceiling. It cost a bomb but was very effective.

carpet underlay
A friend of mine builds speaker boxes and he is a fanatic when it comes to getting the best out of sound dampening the interior of his speaker boxes.
He uses carpet underlay against the interior walls of his speakers then hangs a layer of lead over the underlay. Lead is the deadest material known.

Soundproofing
If it is not too late for a suggestion - my son and I have rehearsal rooms - accoustically engineered - and we had to use soundchek or firechek plasterboard, soundbat insulation and a 300mm gap then plaster again. To cut the reflection of the sound in the room we made baffles that were filled with soundbats. They are just a wooden frame with the insulation packed in and covered with material. If they are recording an instrument within the room they arrange the baffles around the instrument to isolate the sound. The baffles can be connected to surround the instrument or compressor.

just adding my sound proofing story here.....
I help in a sound reduction of some offices and we used a product that was a couple of layers of hessian that had thousands lead balls stuck to it hung over studs then plaster boarded over. The balls being bigger then 2mm and smaller.The idea was that the sound vibrated the lead ball thus using up the sound energy. Sounds good but i was not there for the testing????
I do remember it was very heavy stuff to hang up.vapourforge.com

soundproofing
BobL,
I suppose that I did not make the point clearly - I really meant to stress the baffles around the noise source does really make a big difference within the room.
If you constructed a timber frame around the compressor and filled the frame with csr sound bats I am sure that you would significantly reduce the noise.
Regards,Smithy
