Does an R410A compressor give of any more noise than an R22 compressor
(all else being equal eg. brand, quality of unit, installed noise
suppression, etc.)?
If so, how significant is the difference?

You are full of? it would be better that you stick to what you know!
Cavitations can occur only in pumps that pump liquid unless you have
new dictionary for all of us, that knows what cavitations is and when it can
occur.
Jake I have consider you to be little smater then that.

Dildo, you dumbass, why don't you do some homework:
