    Abstract: A wearable computing device can receive, via at least one input transducer, a first audio signal associated with ambient sound from an environment of the device. The device can then process the first audio signal so as to determine a second audio signal that is out of phase with the first audio signal and effective to substantially cancel at least a portion of the first audio signal. The device may then generate a noise-cancelling audio signal based on the second audio signal, based on a third audio signal, and based on one or more wearer-specific parameters, where the third audio signal is representative of a sound to be provided by the device. The device may then cause a bone conduction transducer (BCT) to vibrate so as to provide to an ear a noise-cancelling sound effective to substantially cancel at least a portion of the ambient sound.

    Abstract: Example embodiments may relate to methods and systems for adapting an array of piezoelectric transducers, placed on a head-mounted device (HMD), to different head sizes. For example, an HMD (e.g., a wearable computer) may include an array of transducers that are configured to operate as bone conduction transducers (BCTs), and alternatively as pressure sensors. In particular, methods and systems may be implemented to determine a respective power level for each vibration transducer in the array based at least in part on a determined mechanical load on each transducer in the array. Once the respective power level for each vibration transducer is determined, the system may cause each vibration transducer in the array to operate at the determined respective power level.
