Hmm... My eheim 2211 is silent. Did it purge the air completely? I had to give mine a little shake to get some air bubbles out.
If you are talking about the quick release valves you just cut the tubing and put it on either end of the valves. It lets you move the filter or take off the input/output for cleaning without having water go everywhere
It should definitely be quieter than any HOB filter you own...
