I have 3 of the 2640 SpeedWave's in my sump (return + closed loop + utility), and they are silent on full power. I can hear the bubbles from the skimmer over the 3 pumps together.
One of the most important things with pump noises to ensure is that their vibrations are isolated from your plumbing.... It's amazing how a small vibration can be magnified and be very loud if it resonates through your entire return plumbing. Flex tubing right from the pump (if even just for a foot or so) will help noise from any pump immensely!

speedwave's are really quiet - like, really.. really quiet. But make sure you have a backup, as mine (as well as a lot of others) die within 6 months.
The Tunze silence is what I replaced it with, and it's quiet - but not as quiet, as the speedwave. Out of all I've used, those two are the quietest.

I have a QuietOne 3000 and it runs perfectly silent unless it's touching a wall in my sump. The Eheim pumps I have definitely run a little more noisy but still close to silent.
