Abstract: An open-ear device performs active noise cancellation (ANC) for a user. A sensor located outside an ear of a user which does not occlude an ear canal of the ear and measures vibrational data indicative of a sound pressure level at a location outside the ear, or a level of pinna vibration of the user. A prediction pipeline generates a prediction of sound pressure within the ear canal using an individualized model, taking into account the measured vibrational data and the unique geometric shape of the user's head and pinna. This sound pressure prediction is used to generate audio instructions for rendering playback at an noise cancellation source, such as a bone conduction transducer and/or cartilage transducer, to perform ANC for the user by cancelling at least portion of the sound received at the ear canal.

Abstract: A method for adjusting sound (e.g., aural) output of a worn audio device includes obtaining orientation or position data that indicates an orientation or a position of the worn audio device. The method also includes determining at least one change in the orientation or position data indicating a change in orientation or position of the worn audio device. The method also includes adjusting or selecting a filter for adjusting aural output produced by the worn audio device using the orientation or position data, and operating the worn audio device to provide the sound output using the filter in response to the at least one change in the orientation or position data.
