Abstract: An audio device is disclosed comprising an interface, a memory, one or more processors comprising a signal processor, one or more speakers, one or more microphones, and an ultrasound device. The audio device is configured to output an output ultrasound signal via the ultrasound device; obtain an input ultrasound signal via the ultrasound device; obtain an audio input signal via the one or more microphones; determine, based on the audio input signal, a direction of arrival of the audio input signal; determine, based on the input ultrasound signal and the output ultrasound signal, position data including first position data indicative of a first position of a first moving object; determine whether the direction of arrival satisfies a position criterion based on the first position data; process the audio input signal based on whether the direction of arrival satisfies the position criterion for provision of an audio output signal.

Abstract: An audio device comprising, an interface, one or more first output transducers, one or more input transducers, and a processor. The audio device is configured to emit a first ultrasound signal, receive a first reflection indicative of the first ultrasound signal, process the first reflection to determine movement, and in response to movement being determined, adjust one or more audio processing parameters of the audio device.
