INTRODUCTION TO LOW-POWER MEMS MICROPHONES SECRETS

 The sounds flooring is often expressed being an equal input sound in dB SPL by subtracting the SNR with the audio force stage the sensitivity is measured at (typically 94 dB SPL). The lesser air volume from the back chamber of classic top rated port MEMS microphones makes it tougher with the membrane to maneuver, which hurts the sensitivity in t
