how to use k10 mic to monitor environment sound level

hi, 

I'm searching for a way to my K10 to monitor the sound level of my room, and to react with an action when the sound level gets above a certain level.

but when I check Mind+ and the docs here https://www.unihiker.com/wiki/K10/Examples/examples_mpy/#on-board-sensor-record-play I only find examples for recording and playing back.

I wanted to do something like this first:

https://microbit.org/projects/make-it-code-it/sound-meter/

and preferably using MicroPython, if possible.
