that SA-H1011 is just awesome, i gotta try one, i wonder how it sounds,

have you started recording audio?

Thanks Martin, go easy testing
Yeah, I'll need to suppliment with an audio recording of some sort. I've been running a few experiements, but havn't landed on a method yet. For example, the San Ace does really really well on cfm per noise level, but it's not as smooth of a noise as some of the others. I've also read a little bit how every one person has a different sensitivity to noise and what is perceived as loud or annoying. So matter what the tool to measure noise, it's only a really rough guide and it's pretty much impossible to quantify noise that would be agreeable to everyone out there.

I've got the ambient level recorded for every test. They are all right in there at about 47-49db. So while the relative numbers won't be much different, I could easily enough make a chart for dB rise vs noise or whatever..
