    Abstract: An acoustic device includes at least one acoustic transducer disposed such that, in a head-worn state, the at least one acoustic transducer is in an open-ear configuration in which an ear canal of a user of the acoustic device is unobstructed. The acoustic device also includes an array of two or more first microphones that captures audio preferentially from a first direction as compared to at least a second direction different from the first direction, wherein the audio captured using the array is processed and played back through the at least one acoustic transducer, and an active noise reduction (ANR) engine that includes one or more processing devices. The ANR engine is configured to generate a driver signal for the at least one acoustic transducer, the driver signal having phases that reduce effects of audio captured from at least the second direction.

    Abstract: In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.

    Abstract: An earpiece includes a feed-forward microphone coupled to the environment outside the headphones, a feedback microphone coupled to an ear canal of a user when the earpiece is in use, a speaker coupled to the ear canal of the user when the earpiece is in use, a digital signal processor implementing feed-forward and feedback noise compensation filters between the respective microphones and the speaker, and a memory storing an ordered sequence of sets of filters for use by the digital signal processor. Each of the sets of filters includes a feed-forward filter that provides a different frequency-dependent amount of sound pass-through or cancellation, which in combination with residual ambient sound reaching the ear results in a total insertion gain at the ear of a user.

    Abstract: Various implementations include wearable audio devices and related methods for controlling such devices. In some particular implementations, a computer-implemented method of controlling a wearable audio device includes: receiving an initiation command to initiate a spatial audio mode; providing a plurality of audio samples corresponding with spatially delineated zones in an array defined relative to a physical position of the wearable audio device, in response to the initiation command, where each audio sample is associated with a source of audio content; receiving a selection command selecting one of the plurality of audio samples; and initiating playback of the source of audio content associated with the selected audio sample.
