So I picked the very first mems microphone datasheet my ddg gave me: https://www.st.com/resource/en/datasheet/mp34dt06j.pdf https://www.st.com/resource/en/datasheet/mp34dt06j.pdf ..and it says 10 ms max turn on time, so 100 Hz. Of course, a typical or minimum turn on time could be better, but I imagine it it were better, it would be advertised as well.
