Let's try to clarify some common misunderstanding on the difference between a measurement microphone (e.g. UMIK-1/UMIK-2) and a voice microphone on your laptop/PC/headset. The typical question being:
"How come my laptop PC shows lots of signal when I talk while my UMIK-1 doesn't?"
The answer goes as follow:
A voice microphone is tuned to pick up voice and has high sensitivity to be able hear small sounds. You don't want to be shouting to be heard on your Zoom meeting. So far so good?
A measurement microphone like the UMIK-1/2 on the other hand is tuned to measure high spl (= loud signals from your loudspeakers). For that application, the "sensivity" of the microphone is lower so it takes a higher SPL signal to register full scale. That's the purpose of this measurement microphone after all = Measure your loudspeaker.. :-)
The keyword to remember is "sensitivity" of a microphone. Different application, different electronic design.
Software like REW/Dirac live and others will have no problems to deal with this as they "know" it's a measurement microphone and expect high SPL. Your laptop PC will easily clip the signal while a UMIK-1/2 will not.
Hoping this clarifies
