S-VM2020-C MEMS Omnidirectional Microphones Audio Evaluation Board

Vesper Technologies Inc.

Microphones are often exposed to loud sounds either due to music playback from a nearby loudspeaker or from heavy industrial equipment or other environmental noises. For example, a smart speaker can play music as loud as 150 dB SPL at its high-volume setting. With a capacitive MEMS microphone, speech recognition accuracy takes a hit since the microphone next to the speaker can saturate even before listening to the user. Capacitive microphones can only go up to low 130 dB before introducing significant distortions.
