I am starting to build two walls in my basement to make a woodworking shop. One existing wall is constucted of a stud wall with thin paneling overlain by peg board. The other existing wall is concrete block. The ceiling is rafters with electrical conduit and water pipes suspended on the bottom side of the rafters. What is the best way to minimize the most sound possible from being heard in the house during the use of woodworking equipment such as table saw, joiner, planer?

Dust control is also a concern but easier to control than noise.

I have covered this before, but cannot find it. Sound is transmitted by vibration. The wall vibrates, the vibrations pass through the studs to the other wall, it vibrates, and the sound enters the adjacent room. Right away, it becomes clear that insulation is not the key. You can build a wall with 6 inch plates and 2x4 studs offset so that no stud is on the face of both walls. Essentially, two sets of studs in almost the same space as one set in a single wall. This will go a long way to stop the transmission of sound from one room to the next. Of course, sound can travel through doors and duct work, but they are generally smaller than the wall involved.

You could do this same sort of thing to some degree with your ceiling, if vertical space permits.

Let me now if this helps.
