Thanks guys. I'm actually more concerned about the noise it produces. I have a friend of mine, who nails egg trays on the walls to reduce the noise. Have anyone tried this?
much better is to make a shallow frame from scrap wood, line the back with screen, pack rock wool or fiberglass in the frame, cover front with screen. or, use fabric instead of screen, depends on how pretty you want em.
instant sound absorbing panels. slap em everywhere around the machines. dont need 100% coverage, even 25 - 50% will drop dbs.
HVAC ductboard works as well,1 1/2 inch (thin as 1 inch) thick cut to size (or any shape) & 45 degree the edges (if you want) & spray glue & adhere whatever fabric you want on em
You can put a wood frame around or leave em bare
The silver side goes against the wall with velcro or screws or glue.
