    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: The technology described in this document can be embodied in a method that includes receiving an input signal representing audio captured by a microphone of an active noise reduction (ANR) headphone, processing, by one or more processing devices, a portion of the input signal to determine a noise level in the input signal, and determining that the noise level satisfies a threshold condition. The method also includes, in response to determining that the noise level satisfies the threshold condition, generating an output signal in which ANR processing on the input signal is controlled in accordance with a target loudness level of the output signal, and driving an acoustic transducer of the ANR headphone using the output signal.

    IPC: H04R1/10

    Abstract: The technology described in this document can be embodied in a method that includes receiving one or more electronic files comprising information on structural features of a portion of an ear of a user, generating an electronic representation of the eartip or a cast based on a portion of the information on the structural features of the portion of the ear, and producing the eartip based on the electronic representation. The eartip includes an outlet, and a sealing structure disposed around an exterior of the outlet, wherein a first end of the sealing structure is attached to the outlet, and a second, opposite end of the sealing structure is physically separated from the exterior of the outlet. Generating the electronic representation includes configuring one or more structural parameters of the outlet or the sealing structure in accordance with the structural features of the portion of the ear.

    Abstract: A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and an output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

    Abstract: A media playback device has programmable signal processing capabilities and an input receiving signals representative of ambient noise. The media playback device identifies an output response characteristic and an attenuation characteristic of a set of headphones associated with the media playback device, predicts a property of audio output by the headphones at a user's ear based on the ambient noise input signal, the output response characteristic, and the attenuation characteristic of the headphones, predicts expected residual ambient noise at the user's ear, when wearing the headphones, derived from the ambient noise input signal and the attenuation characteristic, and modifies masking audio signals to be provided to the headphones such that they will mask the expected residual ambient noise at the user's ear.
