made a soundproofing box for my air compressor, its damn loud, well over 100db, its a lot quieter now, i can hold a conversation whilst its turned on now, better for me and must be better for the neighbours...
cut the necessary boards and attach polystyrene foam to add to the sound dampening, it all fits together nice and snug
cut some holes in the top piece to release heat and get air in
it actually fitted together really well - i know the 2 end pieces look longer than they should, i knew that they would be too long by about 5mm each, but i didnt think i could cut that thin a slice with my crappy saw, ill try again when i paint it, after taking this pis i also cut some slots in the bottom to send the air line and power line through, as well as aiding airflow
it really cuts down on the sound, must have halved it, am well happy to have done it all in a day
