  • Patent number: 10154149
    Abstract: An audio framework for acoustic feedback suppression. One example portable communication device includes a microphone, a loudspeaker, and an electronic processor. The electronic processor receives an acoustic signal, including an audible component and an ultrasonic component, from the microphone. The electronic processor splits the acoustic signal into a first stream and a second stream identical to the first stream. The electronic processor is removes the ultrasonic component from the first stream to generate a filtered audio stream, and passes the filtered audio stream to a sound server. The electronic processor removes the audible component from the second stream to generate a received ultrasonic stream, and compares the received ultrasonic stream to a transmit ultrasonic stream to determine an acoustic distance. The electronic processor determines an attenuation level based on the acoustic distance, and adjusts an audio component of the portable communication device based on the attenuation level.
