I wish I was further along in my DC system to provide first hand advice, but
here is what I am implementing to achieve the goal of sound isolation for
the dust collector:

I have placed the DC in an enclosed space (an "isolation chamber") that is
pierced in four locations:
1) Air inlet (7" spiral pipe).
2) Air exhaust (6" spiral pipe).
3) Cooling air intake (6" opening)
4) Cooling air exhaust (8" X 14")

The air exhaust is directed outside my shop (my poor neighbors!). I will
have separate vents at the opposite end of my shop (my wife thinks it is a
garage and actually parks her car in it) to provide for an air return.

Based on some very preliminary testing, the DC is quieted down
significantly, although I still have much more soundproofing to do. Some of
the noise is coming through the cooling air exhaust which is open to the
shop. The DC sounds like an F-16 when in the shop, but will probably be
quite tolerable once all buttoned up. Still very noticeable, however.

If you do house your DC in an enclosed space, give consideration toward
cooling the system. In order to achieve a 10 degree C temp rise in my
enclosure, I require 200 cfm cooling air. This is easily accomplished with
a fan from Grainger or other source. If you know how much power you will be
required to dissipate, I would be happy to help you estimate the airflow
required.

Hope this helps!
