How do i Test Microphone Sensitivity?

[CookieMonster]

Hey guys, does anybody know what instrument i need to use to test a microphone's sensitivity? I can't find any kind of multimeter that measures small enough currents.

Many Thanks, Cookie.

Use a mike-amp of known gain, plus a meter.

In general you will also want a warble source in an anechoic chamber and a reference mike or calibrated sound source.

Thanks, that's a big help.

The Bruel&Kjaer Pistonphone is the standard tool for for "calibrating", mics, i.e. measuring their sensitivity.

Whisper into it see if it "responds". :green:

Sorry, bad joke, I know. :twisted:
