What is the difference between microphone types?
I’m often asked what is the difference between free field microphones, diffuse field microphones and pressure microphones.
For a run-of-the-mill ½ inch microphone the short answer is nothing.
However the long answer is a bit more involved.
Basically if the frequency range is below 16 kHz and an accuracy of ±2dB is acceptable then there is no real difference between the types.
So what is the difference between these types of microphone?
