MEMS analog microphone Frequency range 0Hz - over 1000Hz

Greetings,

I’m searching for an analog MEMS microphone with a frequency range from 0Hz to, at least, 1000Hz.

Does anyone have any suggestions? I can’t find one, anywhere. I really need the 0Hz-100Hz range.

Thank you.

0 Hz would be a pressure sensor. I wounder what the upper freq response of one of those might be ? Combined w/a wideband mic, the combo might get you the desired range. Outside of a laser mic, I’ve not heard of anything w/a DC freq response.

Do you know of any SMD laser microphones with that kind of frequency range? What is the cost of something like that? Thanks.

SMD !? No such animals exist.
