MASTER NOISE vs CFM CHART
Updated 11-8-10
I'm only going to update this after getting each batch done. What is obvious to me is how extremely tight the results are. Per my reading, it normally takes about 3dbA for most people to perceive a change in noise level...that's about the spread of "Most" of the fans here. But if we're splitting hairs...here is the chart for your viewing pleasure.
Just note this is NOISE LEVEL only. I think this is only half the picture, noise quality is what you get by listening which points out the things like motor tics, and other less that smooth sounds.
