You could measure the amps using an amp meter. It’s not completely accurate but it can tell if there’s a big difference between having the sound inclosure and not. I have never done this although I have read it is a cheaper method for measuring CFM as amps are in direct proportion to CFM. I am in the process of building a new cart for my Delta 50 760 so I can fit my top hat thien separator under it. I was planning on doing something about the sound from the dust collector myself while I’m at it building the cart. Problem with the sound coming from a dust collector is it’s mostly low frequency which are the hardest to get under control because they travel allot farther than highs. Crank49s idea of removing casters and placing foam under the structure/collector is a good idea. I was thinking about doing the same thing with the new cart I’m building. I would definitely like to see pics of whatever you do and hear your results when your done if it’s possible. Good luck to you.
