Noise Level with Sequence pumps?

[Dyspnea]

I'm looking to for a pump to run my planned closed loop system, But since this tank will be in a living area I need a pump that runs quietly as possible. The pump linked below suits my needs the best however I'm curious about the amount of noise they produce.

Any one own a Sequence pump? or have experience with them?
