    摘要: 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.

    摘要: Detection of an uncorrelated component in a multi-channel acoustic signal is disclosed. In one example, the detection is based on a relation between (A) a difference in energy between two channels of the signal and (B) a threshold value that is based on an estimate of background energy of the acoustic signal.

    摘要: An electronic device for controlling noise is described. The electronic device includes a force sensor for detecting a force on the electronic device. The electronic device also includes noise control circuitry for generating a noise control signal based on a noise signal and the force. Another electronic device for controlling noise is also described. The electronic device includes a speaker that outputs a runtime ultrasound signal, an error microphone that receives a runtime ultrasound channel signal and noise control circuitry coupled to the speaker and to the error microphone. The noise control circuitry determines at least one calibration parameter and determines a runtime channel response based on the runtime ultrasound channel signal. The noise control circuitry also determines a runtime placement based on the runtime channel response and the at least one calibration parameter and determines at least one runtime active noise control parameter based on the runtime placement.

    摘要: A method for processing a multichannel audio signal may be configured to control the amplitude of one channel of the signal relative to another based on the levels of the two channels. One such example uses a bias factor, which is based on a standard orientation of an audio sensing device relative to a directional acoustic information source, for amplitude control of information segments of the signal.
