Sensitivity: It reflects the efficiency of the sound-electric conversion of the microphone. The transmission sensitivity includes sound pressure sensitivity and sound field sensitivity.

1. Sensitivity: It reflects the efficiency of the sound-electric conversion of the microphone. The transmission sensitivity includes sound pressure sensitivity and sound field sensitivity. The sound pressure sensitivity refers to the output voltage of the microphone when the sound pressure on the diaphragm of the microphone is 1Pa.
2. Frequency response: Since the sensitivity is related to the frequency of the sound, when the frequency changes, the sensitivity also changes. Therefore, the frequency response of a general microphone is a curve.
