Title: Microphone sensitivity and the output voltage Post by CHL on Jan 19th, 2015, 10:46pm Hello I have a question about microphone's sensitivity 1) For the sensitivity, the reference is 0dBV which means 1V. Is it always same even though the microphone supply voltage is different?(e.g. 1.5V microphone VS 3.3V microphone) 2) If the question above is correct, does it mean all of the microphones cannot achieve 1Vrms output signal? Are the output signals always mV range? |
