Why TEDS Microphone(GRAS 46BD_FV) Calibrated Sensitivity get wrong Value?

If you want to measure the sensitivity of the Reference Mic, the method is the same just change the task Type to AI-Voltage and insert the external amplifier, everything else can remain the same.

Now, the measurement you get is in Vrms, if your test stimulus is 94dB SPL 1kHz tone, then the Vrms directly translates to V/Pascal

Thanks,set up task type "AI_Voltage" measured Microphone sensitivity.
