How about using a lap top with a real time (spectrum) analyzer.

You also need a high frequency acoustical hiss generator like an
aerosol can of air that hisses when you push the button. (Don't direct
the air AT the mic obviously)

You can get a pretty good idea of the high frequency resonse this way.
Doesn't work too well for the bass and mid-range.

Anybody have any ideas for a good portable acoustical white noise
generator or maybe an impulse generator. If you can generate good
acoustical white noise or impulses, you could do a pretty good mic test
with a lap top ( and mic pre.)
