How can I soundproof my shop vacuum and compressor in the shop without choking off the air that both machines need?
John Brock: Ideally, place them outside in weatherproof sheds. In my shop, that’s not an option, so I have ear protectors hanging on hooks all over the shop.
Michael Dresdner: Build a box around them lined with fiberglass insulation. As luck would have it, fiberglass is also an outstanding noise insulator. Have a filtered air intake and exhaust.
Carol Reed: Provide air-intake from outside. Use a clothes dryer vent for a tidy solution.
