Abstract:
A method includes receiving an ultrasound signal at an ultrasound receiver from an ultrasound transmitter. The method also includes detecting movement of at least one object based on the received ultrasound signal and at least one previously received ultrasound signal. The method further includes modifying a parameter of an acoustic echo canceller in response to the detected movement.
