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.

Wearable device with at-ear calibration

An audio system (e.g., of an artificial reality headset) determines a position of the headset relative to a position of a head of a user wearing the headset. The determination is based in part on an image of a portion of the head from a tracking camera (e.g., eye tracking and/or face tracking) on the headset. The audio system adjusts an acoustic parameter based in part on the determined position of the headset. The audio system performs an action that uses the adjusted acoustic parameter.

Adjusting acoustic parameters based on headset position

A method for generating an individualized audio output response for a headset based on images of a user's ear. An image of a portion of a user's head including at least the user's ear is received, the user in the image wearing a headset including a plurality of visual markers. One or more features describing the user's ear are identified based at least in part on a position of one of the plurality of visual markers relative to the user's ear that are used to disambiguate orientation and/or scale of the features in the image. The one or more features are input to a model, and the model is configured to determine an audio output response of the user based on the extracted one or more features. An individualized audio output response is generated for the user based on the audio output response, the individualized audio output response configured to adjust one or more acoustic parameters of audio content provided to the user by the headset.

Personalized equalization of audio output using visual markers for scale and orientation disambiguation

A method for generating an individualized audio output response for a headset based on a representation of a user's ear. One or more images of a portion of a user's head including at least the user's ear are received. A representation of the user's ear is generated based in part on the one or more images. A simulation of sound propagation from an audio source to the user's ear is performed based on the representation. An individualized audio output response is generated for the user based on the simulation, the individualized audio output response configured to adjust one or more acoustic parameters of audio content provided to the user by the headset.

Personalized equalization of audio output using 3D reconstruction of an ear of a user

A method for generating an individualized audio output response for a headset using a machine learning model. One or more images of a portion of a user's head including at least the user's ear are received. One or more features describing the user's ear are identified based on the one or more images. The features are input to a model, and the model is configured to determine an audio output response for the user based on the identified one or more features. The audio output response describes one or more acoustic parameters perceived by the user. An individualized audio output response is generated for the user based on the audio output response, the individualized audio output response configured to adjust one or more acoustic parameters of audio content provided to the user by the headset.
