I saw this done on this forum a few times and decided to try it for myself. I have a 21 Gallon oiled compressor from Harbor Freight. It works well enough for my weekend tinkering but it was so loud I had to keep hearing protection on any time it was charging. I had most of the materials for this project lying around so I figured it was worth a shot. The noise is substantially reduced, I can now have a conversation or listen to music in the garage. The sound meter app on my phone went from pegged out at 85 db from 20 feet away to 62db standing directly in front of the compressor. And it looks good too!
Building the box out of 1x2 and old 1/2 MDF I had laying around.
Added a plug, 20A switch and outlet to power the compressor and exhaust fan. The fan is a $13 bathroom exhuast fan from Home Depot.
I lined the inside of the box with acoustic ceiling tiles, you can buy them at home depot, they only have an acoustic rating of .55 but combined with the MDF they work well and they are cheap.
I used expanding foam insulation in a can to seal up the joints between the tiles and drilled some intake holes near the bottom for fresh air. Then I mounted a hose reel on top and painted the box to match my cabinets.
I am very pleased with this box.
