I'm thinking about getting this power supply
http://www.quietpcusa.com/acb/showde..._ID=30&CATID=2

It's rated "Less than 17 db (A)" in Acoustic noise level.
http://209.47.233.50/acb/webpage.cfm?DID=8&WebPage_ID=6

Is there a place I can read a comparison in about how loud certain db's are.
I remember reading something about 40 db is about whispering level, 60 db is
about this level. . . etc.
Is there something like that around?
I just wanted a general idea of how loud 17 db's are and to look at other db
ratings.

Thanks
