EFFECTIVE CALIBRATION METHOD FOR SOUND PRESSURE SENSITIVITY OF CAPACITOR MICROPHONE

The calibration of the measured sound of a capactior microphone is the foundation of precise measurements.The coupling cavity method can precisely calibrate the sound pressure sensitivity a capactior microphone,but it is very complicated for actual application.It is necessary to find a convenient method for the calibration of capacitor microphones.This paper presents an effective and quick method to calibrate the sound pressure sensitivity of capactior microphones,It meets the reqirement of many practical applications.
