I don't know about those filters, but I've had Aquaclear 10/20's in my bedroom and they're silent until the impellor wears out (3 years at least)
The loudest ones i've had were the Biowheel ones and a "Tetra" branded one. Horrible. (Penguin?)
filters, I totally recommend AquaClear, just get one size "bigger" than recommended. You can always adjust it down.
