Hi, do you have data and information about infrasound characteristics of MP34DT06J ? 

I looked at its frequency response in the data sheet, but information is being plotted starting from 100 Hz only. 

I'm using the CCA02M2 board.

Many thanks!

    Hi @MSant.1​ , what do you mean with "infrasound" characteristics? The usual characterizations is performed in the [20Hz, 20kHz] band, so I can share you a typical frequency response in this range from characterization lab. The FR is almost +-2dB flat down to 30Hz.

    Hi, sound from combustion processes may be in infrasound range, i. e. below 20 Hz. This is my target application.

    Hi @MSant.1​ , ok, I can share you the average behavior down to 10Hz, because the standard detailed characterization is limited to 20Hz.
