Several folks asked that I followup on the effectiveness of the DC closet I recently built to contain noise. In one word..."Incredible". The motor/blower is almost "silent" from the shop and the only real noise is from the open gate...that level varies with the type, size and configuration of the hood, etc.
The construction is 2"x4" studs, filled with fiberglass batts and covered with pegboard (rough side exposed) on the inside and pine plywood paneling on the outside. The areas between the joists were filled with fiberglass batts sandwiched between 1/2" homasote. ('Cause I had it available from the old DC closet walls) The air return is baffled with a complete reversal in direction to eliminate any direct sound transmission and openings are sealed. If anyone is considering building a closet for their dust collection system and compressor, this design is worthy of your consideration.
The pics have been posted before, but I'm including them for anyone who missed the previous threads. The first shows the finished closet from the outside and the second shows the pegboard on the inside.
