I've got one of those pumps, and let me tell you, they're NOT noiseless.
What I mean is the bubbles are very loud, but there is no buzzing from the unit when it's plugged in but turned down.
It's just a variation on the venturi on most internal filters, and even if you turn the air adjuster right down, there are still bubbles.
Best to try and see one in action before purchase.
On the other hand, they're quite cheap
