WebThe specified maximum dB level refers to the point where the diaphragm approaches the backplate, or where total harmonic distortion (THD) reaches a specified amount, typically 3 percent THD. The maximum decibel level that a microphone generates in a certain application depends on the voltage supplied and that particular microphone’s sensitivity.
