    Abstract: Various implementations include wearable audio devices and related methods for controlling such devices. Some approaches include: detecting a change from an on-head state to an off-head state with a first sensor system; calibrating a second, distinct sensor system after detecting the change from the on-head state to the off-head state; detecting a change from the off-head state to the on-head state using the calibrated second sensor system; and adjusting an operating state of at least one function of the wearable audio device in response to detecting the change from the on-head state to the off-head state or detecting the change from the off-head state to the on-head state.

    Abstract: Aspects of the present disclosure provide techniques, including devices and system implementing the techniques, to provide feedback to a user of an event when the user is wearing a wearable device. For example, the wearable device may provide high quality noise canceling audio playback to the user, lowering the user's situation awareness. The techniques include measuring ambient sound using two or more microphones on the wearable device. The measured ambient sound is used to determine a related event worth relaying to the user. Based on the location attribute and sound properties, the nature and/or classification of the event may be ascertained using pattern recognition algorithms according to user threshold settings. Insignificant events that the user prefers to ignore will be ruled out by the algorithm. Upon determining the event that merits the user's attention, the wearable device provides feedback to the user indicating the nature and location of the event.

    Abstract: A method performed by a head-mounted wearable audio output device is provided. The audio output device is worn on a head of a user and includes at least one sensor. The device detects a user activity based on motion of the user's body using the at least one sensor. The devices detects an orientation of the head of the user is one of upward or downward using the at least one sensor. The devices controls at least one of: a level of attenuation applied to external noise or audio output based on the detected user activity and the detected orientation of the head of the user.

    Abstract: Various implementations include wearable audio devices and related methods for controlling such devices. Some approaches include controlling a wearable audio device by: determining a magnitude of an acoustic transfer function based on an electrical signal from an internal microphone and an audio signal from an acoustic transducer at one or more predetermined frequencies; calibrating a proximity sensor; detecting a change in the state of the wearable audio device from one of: off-head to on-head, or on-head to off-head using both the calibrated proximity sensor and the magnitude of the acoustic transfer function; and adjusting at least one function of the wearable audio device in response to detecting the change from the on-head state to the off-head state or detecting the change from the off-head state to the on-head state.

    Abstract: Audio pickup systems and methods are provided to enhance an audio signal by removing noise components related to an acoustic environment. The systems and methods receive a primary signal and one or more reference signals from various microphones. Adaptive filtering and combining minimizes an energy content of a resulting output signal, e.g., to form a substantially null output when the system is in a static acoustic environment. When the system is a playback sound source, one or more echo cancellers may contribute to removing content from the output signal. A change in the acoustic environment, such as a new sound source, causes content in the output signal until the adaptive filtering adapts to the new environment. In some examples, a desired content such as a wake-up word is detected and adaptation is stopped.
