  • Acoustic activity detection
    Patent number: 12238481
    Abstract: Acoustic activity detection is provided herein. Operations of a method can include receiving an acoustic signal at a micro-electromechanical system (MEMS) microphone. Based on portions of the acoustic signal being determined to exceed a threshold signal level, output pulses are generated. Further, the method can include extracting information representative of a frequency of the acoustic signal based on respective spacing between rising edges of the output pulses.
    Type: Grant
    Filed: July 26, 2023
    Date of Patent: February 25, 2025
    Assignee: INVENSENSE, INC.
    Inventors: Tomas Pitak, Igor Mucha, Robert Dick, Michael Tuttle
