1. A system, comprising:
a microelectromechanical system (MEMS) microphone device configured to capture an integrated signal representing an ultrasonic signal and an audio-band signal simultaneously; and
a processing circuitry configured to adjust a configuration parameter associated with the MEMS microphone device based on the ultrasonic signal, wherein the ultrasonic signal is extracted, by the processing circuitry, from the integrated signal based on a determined frequency value of a band filter.
