Abstract: A method performed by a headset that includes a speaker and an in-ear microphone, the method includes performing a calibration on the headset to obtain a baseline measurement; using, while the headset is being worn by a user, an audio signal to drive the speaker that is arranged to project sound into a canal of a user's ear; capturing as a microphone signal, from the in-ear microphone of the headset, sound from within the canal of the user's ear; determining a parameter associated with the user's ear based at least on the captured microphone signal and the baseline measurement; and transmitting a notification related to one or more characteristics of one or more hearing elements of the user's ear based on the parameter.

Abstract: A device may include microphones worn on a head of a user. The device may include a processor, configured to obtain microphone signals from the plurality of microphones. The processor may attenuate breathing sound from the user by processing the microphone signals, resulting in attenuated microphone signals. The processor may render one or more output audio channels based on the plurality of attenuated microphone signals.

Abstract: A conversation detector processes microphone signals and other sensor signals of a headphone to declare a conversation and configures a filter block to activate a transparency audio signal. It then declares an end to the conversation based on processing one or more of the microphone signals and the other sensor signals, and in response deactivates the transparency audio signal. The conversation detector monitors an idle duration in which an OVAD and a TVAD are both or simultaneously indicating no activity and declares the end to the conversation in response to the idle duration being longer than an idle threshold. Other aspects are also described and claimed.

Abstract: Acoustic pickup beams (sound beams) can be formed in a physical environment from a plurality of microphone signals. Each of the sound beams can measure acoustic energy in a direction of the respective sound beam. Directional decay of the acoustic energy measured through each of the sound beams is determined. Room surface acoustic properties of the physical environment are determined based on mapping the directional decay of the acoustic energy to the physical environment. Other aspects are described and claimed.

Abstract: A method performed by a first headset worn by a first user, the method includes the first headset performing noise cancellation on a microphone signal captured by a microphone of the first headset that is arranged to capture sounds within an ambient environment in which the first user is located. The first headset receives, from a second headset that is being worn by a second user who is in the ambient environment and over a wireless communication link, at least one sound characteristic generated by at least one sensor of the second headset and passing through select sounds from the microphone signal based on the received sound characteristic.

Abstract: A plurality of microphone signals can be obtained. In the plurality of microphone signals, speech of a user can be detected. A gaze of a user can be determined based on the plurality of microphone signals. A voice activated response of the computing device can be performed in response to the gaze of the user being directed at the computing device. Other aspects are described and claimed.
