INTRODUCTION TO LOW-POWER MEMS MICROPHONES THINGS TO KNOW BEFORE YOU BUY

 The sounds ground can be expressed being an equal enter sounds in dB SPL by subtracting the SNR with the seem force stage the sensitivity is measured at (typically 94 dB SPL). The smaller air volume during the back chamber of classic major port MEMS microphones causes it to be tougher for the membrane to move, which hurts the sensitivity with th
