How do you find the polarity of electret microphone?
Usually, the negative terminal is internally connected to the microphone's metal shell. Use a tester to measure resistivity between each terminal and the outer shell; if you get zero, you found your "negative". Unless you're into some preci... Read More »

The output value depends on the sound pressure level (dBSPL) applied to the microphone. Without this, no one can give you an exact value. Even a proportionality constant (volts per dBSPL) cannot be exact because there are many different sty...

In a condenser microphone, also called a capacitor or electrostatic microphone, the diaphragm acts as one plate of a capacitor, and the vibrations produce changes in the distance between the plates. There are two methods of extracting an au...
