Need spec sheet for MEMS mics on 4-mic array

Post by ernichol » Tue Apr 17, 2018 6:27 am

Hello,
I have the v1 Respeaker with 4-mic array. I need to figure out the specs for the mic (e.g., sensitivity and reference SPL). Does someone have the spec sheet with the exact part number used on the array, or does someone have the sensitivity/reference SPL data? I need to convert from dBV Output to db SPL Input.

Thanks!
Eric

Hi,
can you please provide which MEMS microphones are in ReSpeaker 2 Mic Array HAT for Raspberry Pi?

Also, in which Respeaker are the best MEMS microphones? And which?
