Just bookmarked that Parts Express mic for future purchase reference. Thanks 90 dB. I love Ethan Winer's no nonsense approach to audio. If you've never seen his audio myths debunked YouTube, schedule yourself an hour and sit back and enjoy.

You don't need a calibrated mic for the purpose of ringing out a room. You only need calibrated mics when you are doing measurements for SPL for reports, which I'm sure you already know. I seem to recall that your handle relates to past familiarity with OSHA's noise exposure law.
