A processing system obtains a deformation signal generated by a deformation sensor. The deformation signal is indicative of a deformation of an outer ear of a user of a hearing instrument. Additionally, the processing system obtains an EMG signal generated by an electrode in a concha of the user, wherein the electrode is configured to detect activity of an intrinsic auricular muscle of the user. Furthermore, the processing system generates information regarding an auditory attention state of the user based on the deformation signal and the EMG signal. The processing system controls, based on the information regarding the auditory attention state of the user, the parameter of the audio system.

The present disclosure relates to an automatic volume adjustment method and apparatus, a medium, and a device, which belong to the field of computer technologies, and can adjust the playback volume of audio or video.

A speaker of a hearing instrument generates a sound that includes a range of frequencies. Furthermore, a microphone of the hearing instrument measures an acoustic response to the sound. A processing system classifies, based on the acoustic response to the sound, a depth of insertion of an in-ear assembly of the hearing instrument into an ear canal of a user. Additionally, the processing system generates an indication based on the depth of insertion of the in-ear assembly of the hearing instrument into the ear canal of the user.

Broadly speaking, the embodiments disclosed herein describe replacing a current hearing aid profile stored in a hearing aid. In one embodiment, the hearing aid profile is updated by sending a hearing aid profile update request to a hearing aid profile service, receiving the updated hearing aid profile from the hearing aid profile service, and replacing the current hearing aid profile in the hearing aid with the updated hearing aid profile.

A method and system for heterogeneous event detection. Sensor data is obtained and divided into discrete data windows. Each data window is defined by and corresponds to a time period of the sensor data. A time-frequency representation over the time period is calculated for each data window. A filter mask is calculated based on the data window corresponding to the time-frequency representation. The filter mask is applied for reverting the time-frequency representation to a time representation, resulting in filtered data. Features, such as extrema or other inflection points, are identified in the filtered data. The features define events, and transforming the time-frequency representation back into the time domain emphasizes differences between more and less prominent frequencies, facilitating identification of heterogeneous events. The method and system may be applied to body movements of people or animals, automaton movement, audio signals, light intensity, or any suitable time-dependent variable.
