Why Are There Two Sensitivity Specifications On My Pcb® Microphone Calibration Certificate? |
|
Answer» The TWO SENSITIVITY specifications represent the same thing. The FIRST specification is open circuit sensitivity in REFERENCE to 1 V/Pa and the second is the converted RESULT in mV/Pa. For example the PCB® 377B02 is -26 dB re 1 V/Pa which equals 50 mV/Pa. The two sensitivity specifications represent the same thing.
