Referring to your "TRICKS OF THE TRADE, VOLUME 4" DVD, project # 10 ("Muffle Your Compressor"), would there be any advantage/disadvantage to line the inside of the box with acoustic ceiling tile to further cut down the noise? I would expand the dimensions to account for the thicker sides.

I found something called Sound Board at the borg (1/2"x4'x8') that may work.

I would definitely look for something along the lines of what Rion is describing, as it will absorb a lot more sound than acoustic tile.

Anything that goes inside the plywood box will help reduce noise. Even Bilt-Rite board from a home center would have some positive effect. If you really want to find an "official" acoustic material, it should have an uneven surface. This breaks up the sound so it can't echo around inside the box, and reduces the chance that it'll find its way to your ears.

Here is my result for the Compressor Muffler:
I do have holes for ventilation. Second best thing about this build was I was able to use up a lot of my scrap wood. BTW, the SoundBoard made just a slight improvement in cutting down the noise and it only cost $11.
Thx for the inspiration, George.

Good job, Rion. It looks very well constructed.
It occurs to me the hose wrap may tend to get cumbersome, especially when the hose wants to twist, or not twist when you want it to. I wonder if you could put a stationary pivot point at the bottom center of the box that is pedal-activated (to lower -- or raise when not wanted, so the box could roll around) and create some kind of channel around the perimeter of the box to contain the hose. You might be able to spin the box to wrap and unwrap the hose.
Something to think about. I'm sure there would be issues I'm not thinking of. For sure, it would make the entire footprint of the appliance larger. Too bad there is no easy way to have made it cylindrical. (Maybe a plastic barrel ? --Maybe the cylindrical shape would deflect the sound waves in such a way it would be quieter ? .. or maybe not.)

Hi Yonak,
You make a good point about the hose wrap. I had considered this to be a problem, also. I had a few random thoughts about a possible solution and now you gave me an additional one. Thx.
BTW, the dolly was an unused left-over from a previous project and I may re-do that, also.
