    As far as I know these little compressors operate at around 43 dB, why would you need to dampen it, if yiu really need to just get a huge carboard box and line with sound insulating foam but you will need to install a cooling fan to stop it overheating, I reckon your fan could make more noise than the compressor.

    I dont have a good suggestion for that one other than enclosure.
    Maybe thinking along the lines of a cooler with a fan or two installed.

    Guess you could stick it inside a mini fridge.

    Is sitting on a table about 12 inches away from me, besides a baffle box I thought just get several extra airlines ,connect together and put in another room. Though longer line might pick up moisture, compressor has a little water trap. It does make quite a racket, when refilling.

    Is the table amplifying it?

    I've had the same compressor and just had it under my table at my feet, it made so little noise that it just didn't annoy me or anyone else, but as I said a cardboard box hust bigger than the compressor itself with sound insulating foam would reduce the noise even further, you can find the foam at B&Q it's not that expensive and it's usually black or grey and looks like the egg box foam you see in camera cases, then all you need is a small desktop cooling fan pointed at through a hole in the box, put vent holes on the opposite end.

    Lengthening the hose will also cause the compressor to overheat because the compressor will have to work hard to get the air to it's destination, it effectively increases the volume of the tank by acting like a second tank and the small motor just isn't designed for it, have you not considered getting small Bambi type compressor with fridge motor, even try looking to a second hand one.

    The compressor I have now is 66 dB and it doesn't bother me in the slightest.

    Your standard airbrush hose shoukd be around 2 to 3 metres long, so you can easily get it about 1.5 metres away from you even if it's only 2 metres.

    The compressor is sitting on a small wooden foldable table, which itself is sitting on top of 3 sets of breeze blocks. Why? because I have a kitchen table sitting on 3 layers of concrete blocks, with a plywood peg board on top to hold my carving wood in position. On top of table I have an MDF shelf temporarily resting on 3 bricks to hold the two large monitors for viewing my music software. At moment have large square of MDF resting against shelf as an easel, copier paper pinned on it, just to practice on.

    This is the only small compressor baffle box design have come across
    http://cowsandchocolate.blogspot.co.uk/2014/09/soundproofing-your-compressor.html
    His seemed quite neat to me.
    In the past looked into the larger versions for my big compressor I think I could adapt their design to a smaller scale.

    Bought several ComArt 1 oz paints last week, opaque and trans, these are the colours Raphael Schnepf uses in his workshops and uses the same set in his airbrush coloring sandcarved glass project.The height of the table is brought to a suitable height for carving. I also have a telescopic bar stool to sit on.

    Just put compressor on carpeted floor, at first thought quite a reduction in sound, put it on top of breeze blocks with 3 carpet tiles underneath, not much of a reduction. The reduction in sound first when put on floor I think because further away from me. I still find the sound quite intrusive, as learning would like to me as quite as possible.
    I'll look into making baffle box, Malky, thanks for tip on B&Q with luck they still stock or prob get on Ebay. No not thinking of Bambi. I tell you guys, you would be surprised, the cost of 6mm glass to practice carving on .
    Cheers :)

    B&Q will definitely have it, it'll be in building section, it's used for sound insulting small music studios and parts of domestic buildings where needed.

    If you want to get a bit pro with it you could make your box out of wood. :)

    I'm going into town Friday to do a few things, will ring B&Q to see if have, if do will pop in and get enough foam to make box for my compressor.
    MDF will do me, tart up with coat of paint, handle etc, to look nice, will post picture when done.
    Cheers :)
    Ps those Chinese Iwata clones I got from Amazon, from what little I know, they seem to work very well but long term I'll find out it if stay that way.

    I just checked, B&Q don't stock it but I did find this.

    It's also handy stuff to line cases to protect stuff, I used to use it for my RC transmitter cases when I flew model planes.

    I rang B&Q earlier but he didn't ring me back. Before I rang B&Q I checked Ebay and Amazon, saw on Amazon 24 sheets 12" x 12" for £31 Prime delivery.
    Didn't see the cheaper ones, thanks, think will also use to line big baffle box for my sandblast compressor.

    You're pretty serious about your silence. I fully expect a question about how to get mice to eat Beanolol:D

    The one I have isn't identical, but similar. Extremely quiet! Still...... You might try an old trick Yamaha et al used with air cooled 2 stroke engines - bits of rubber to dampen down any ringing between the cylinder fins.
    But I think I'd go for a longer hose and putting the compressor outside.

    Here its about $4 a square foot , cut to size. Though if i actually wanted little 30x30cm pieces it would be cheap or free as remnants from the local custom glass place.
