I want to box in a noisy shop vac (from Ridgid) to minimize its noise

I've seen muffler-like attachments that connect to the exhaust. I'm
not sure that a box surrounding the vac would be effective. The first
thought would be that it would limit it's mobility.

Recently, I've started wearing ear muff protection when I use my
whining Milwaukee vac. As I get older, I have to save as much of my
hearing as I can.

Yes, I have already had that muffler-like attachment on my Ridgid shop
vac. Unfortunately, it doesn't do a thing. I really cannot tell if it
makes any difference at all in term of cutting down noise. I believe
the main problem is that the noise seems to be coming from the motor
that is on top of the shop vac, and not from the blower port.
Therefore, attaching the muffler-like attachment to the blower port
doesn't really cut down on the noise in my shop vac.

Thanks for the info anyway. Your info may help other people whose shop
vacs have a different design than mine.
