KY-038 Microphone Sound Sensor Module with Arduino
It detects the sound with the help of a microphone and then feeds this sound to processing circuitry which consists of an operational amplifier LM393. It also consists of a potentiometer which is used for setting the sound level and by setting this sound level the output of this sound sensor module could be easily controlled.

Basic principles of MEMS microphones - EDN
May 14, 2014The signal-to-noise ratio is the difference between a microphone’s sensitivity and its noise floor and is expressed in dB. The SNR of current MEMS microphones ranges from about 56 dB to about 66 dB. Sensitivity. The sensitivity of a microphone is a measure of its response to a given sound pressure level.
