re: Noise reduction from inside to outside the shop…

Good stuff, thanks! One thing I keep finding in my research is about caulking the edges and using putty pads around boxes. If you surface mount the boxes, that’s not an issue, but at least backfilling routing holes with spray foam and the like. Most of what I’ve read revolves around adding mass, so that track as well…thanks for the input! If anyone else has any, I’m all ears…
