What's the real answer? I'm curious as well.
And to the guy that made the "noise = energy = bad" comment. Right concept, wrong application. Nice try, though. Save it for the next time you hear some one slapping their feet when they run and use.
the differences in sound come from different combinations of materials, spring tension, engagement points/pawl count, how the hub or wheel amplifys the sound or resonates....etc....a little bit of everything.
