MEMS Microphone

MEMS is an abbreviation for Micro-Electro-Mechanical-Systems. These microphones are generally manufactured from a processed slice of silicon. As the microphones are small and cheap, they are widely used as built-in transducers for mobile phones and other smart devices. MEMS microphones have not reached the sound quality of electret microphones, not even the miniatures. The self-noise and the distortion in MEMS are higher compared to typical miniature electret microphones.
