  • Publication number: 20240040297
    Abstract: A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.

  • Publication number: 20230370765
    Abstract: A method that includes determining a level of sound within an acoustic environment captured by a microphone; receiving, from a headset worn by a user, data indicating an audio processing mode in which the headset is operating; determining a level of attenuation of the sound based on the audio processing mode and the level of sound; estimating sound exposure based on at least the level of attenuation and the level of sound; and transmitting the sound exposure to an application program.

  • Publication number: 20230367542
    Abstract: The present disclosure generally relates to user interfaces and techniques for managing and visualizing sound reduction using a computer system. In accordance with some embodiments, the computer system displays an indication that a second noise level is less than a first sound level when the computer system is using a sound reduction device. In accordance with some embodiments, the computer system displays a representation of a noise level at a plurality of different times that indicates a first noise level when a sound reduction effect was in effect, and that indicates a second noise level when the sound reduction effect was not in effect. In accordance with some embodiments, the computer system displays a representation of a sound reduction level for a first time period and receives an input selling a second time period different from the first time period, and in response to the input, the computer system displays a representation of the sound reduction level for the second time period.

  • Publication number: 20230195412
    Abstract: A headset can include left and right ear-worn speakers and a control. In response to a control input of the control, the ear-worn speakers can be driven with driver signals that include a control sound having a virtual location determined by spatial auditory cues. The control sound can indicate a behavior of the control as a result of the control input. Other aspects are also described and claimed.

  • Patent number: 11276384
    Abstract: An audio system has an ambient sound enhancement function, in which an against-the-ear audio device having a speaker converts a digitally processed version of an input audio signal into sound. The audio system also has an acoustic noise cancellation (ANC) function that may be combined in various ways with the sound enhancement function, and that may be responsive to voice activity detection. Other aspects are also described and claimed.

  • Patent number: 11172298
    Abstract: While a first wearable audio output component of a wearable audio output device is in a first position relative to a first ear of a user and a second wearable audio output component of the wearable audio output device is in the first position relative to a second ear, a computer system operates the wearable audio output device in a first mode. While doing so, the computer system detects a change in position of the first component from the first position to a second position; and, in response, while the second component is maintained in the first position, the computer system transitions the wearable audio output device from the first mode to a different, second mode that is a pass-through mode in which audio outputs provided via the wearable audio output device include pass-through audio components that include at least a portion of ambient sound from the physical environment.

  • Patent number: 11153677
    Abstract: An audio system has an ambient sound enhancement function, in which an against-the-ear audio device having a speaker converts a digitally processed version of an input audio signal into sound. The input audio signal may be amplified where the amplification may be in accordance with a stored hearing profile of the user (personalized ambient sound enhancement.) The audio system also has an acoustic noise cancellation (ANC) function that may be combined in various ways with the sound enhancement function, and that may be responsive to voice activity detection. Other aspects are also described and claimed.
