Fazua claim their system is quieter than their competitors (well, it is their publicity!).
I'm impressed that a manufacturer has bothered to address the issue of noise.
I'll leave you experts to work out who the competitors are, but most (all?) appear to be crank-based.
Summary: Quiet enough not to annoy, but loud enough to confirm it's working.
I'd say that's about right from my experience.
