Comment on Motion sensors in high-performance mice can be used as a microphone to spy on users, thanks to AI — Mic-E-Mouse technique harnesses mouse sensors, converts acoustic vibrations into speech

  Human speech is between about 130-300Hz, so even with a lower poling rate it can pick it up. And assuming she sound like a mosquito, it’ll pick things up.

    I doubt it, 300Hz is very low. The lowest fidelity frequently band used in telephony is comprised between 300Hz and 3400Hz, specifically excluding everything below 300Hz (voice frequently)

      The human voice typically ranges from 85 Hz to 255 Hz for adults, with males often around 85 to 155 Hz and females between 165 to 255 Hz.

        In these sources they are talking about the fundamental frequency of human Speech F~0~. Which is one important indicator but I don’t think this band is sufficient for comprehension. Record yourself, apply a low-pass filter with cut frequently at 300Hz and check for yourself if this is enough to understand. It might be enough to make out some words, but I doubt it’s enough to hear clearly.
