  • Patent number: 11218824
    Abstract: A head-mounted device can effectively manage heat while also managing noise output levels in a manner that preserves the user's desired experience with the head-mounted device. The head-mounted device can manage sound levels of a cooling system based on detected a sound level of ambient noise in a vicinity of the head-mounted device. For example, the head-mounted device can operate a fan at a speed that produces noise at a sound level that is low enough to be masked by the ambient noise perceived by the user. By further example, the sound level of a cooling system can be based on a sound level of a speaker of the head-mounted device providing audio to the user. By further example, other operational parameters of a cooling system can be controlled to manage noise at a sound level that is sufficiently low.

  • Patent number: 11190896
    Abstract: An audio system and a method of using the audio system to determine an interaural head-related transfer function (HRTF) parameter, are described. The audio system can generate binaural recordings using microphones that are worn by a user in everyday scenarios. The audio system can measure interaural parameter values of selected segments of the recordings, and the measurements can be accumulated over time. The interaural HRTF parameter can be estimated based on the measurements. The interaural HRTF parameter can be used to adapt a generic HRTF to generate an individualized HRTF for the user. Other aspects are also described and claimed.

  • Patent number: 11178478
    Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and computer-readable devices. An audio processing device plays a source audio signal, including causing the source audio signal to be audibly output by an electroacoustic transducer of a user earpiece. The audio processing device records, while playing the source audio signal, a recorded audio signal using the electroacoustic transducer. The audio processing device identifies one or more parameters that indicate how properties of the user earpiece affect playing of the source audio signal, at least one of the parameters being temperature dependent. The audio processing device determines a temperature value estimated to cause the source audio signal that was played by the audio processing device to result in the recorded audio signal, accounting for changes to the source audio signal that occur due to the one or more parameters.

  • Patent number: 11172296
    Abstract: Example techniques may provide volume enhancements to a media playback system. An example implementation involves a first playback device in a first playback configuration playing audio at a first volume level and storing the first volume level in association with the first playback configuration. The first playback device receives instructions to change to a second playback configuration. Based on receiving the instructions, the first playback device joins a synchrony group with a second zone and adjusts the first playback device to play audio at a second volume level which is based on a volume level of a second playback device in the second zone. While in the second playback configuration, the first playback device receives instructions to change to the first playback configuration and, based on the instructions, leaves the synchrony group and adjusts the first playback device to play audio content at the stored first volume level.
