Abstract: The disclosure presents a hearing device system and a method for adjusting hearing aid configuration, where a user is wearing a hearing device, the method comprising transmitting a first background sound signal to the hearing device, transmitting a first sound pattern to the hearing device, evaluating, via a camera unit, a first pupillary information of a first eye of the user in response to a first sound scene comprising the first background sound signal and the first sound pattern. The evaluating may be repeated providing at least a second pupillary information of the first eye of the user in response to a second sound scene being different from the first sound scene, and where an averaged pupillary information is provided based on an average between the first pupillary information and at least the second pupillary information, and selecting a pupillary fitting model based on the averaged pupillary information, determining a first parameter and at least a second parameter of the pupillary fitting model based on the averaged pupillary information, classifying the averaged pupillary information into either a first category or at least a second category based on the first parameter and the at least second parameter, and wherein the hearing aid configuration is adjusted if the averaged pupillary information is in the first category, and the hearing aid configuration is not adjusted if the averaged pupillary information is in the second category.

Abstract: A hearing assistance system comprises an input unit for providing electric input sound signals ui, each representing sound signals Ui from a multitude nu of sound sources Si, an electroencephalography (EEG) system for recording activity of the auditory system of the user's brain and providing a multitude ny of EEG signals yj, and a source selection processing unit receiving said electric input sound signals ui and said EEG signals yj, and in dependence thereof configured to provide a source selection signal Ŝx indicative of the sound source Sx that the user currently pays attention to using a selective algorithm that determines a sparse model to select the most relevant EEG electrodes and time intervals based on minimizing a cost function measuring the correlation between the individual sound sources and the EEG signals, and to determine the source selection signal Ŝx based on the cost functions obtained for said multitude of sound sources.

Abstract: A method for calculating gain in a hearing aid includes: recording electrical activity of the brain in response to a sound signal, computing a temporal response function based on the recorded activity, comparing the computed temporal response function with a template temporal response function, and calculating a gain in the hearing aid based on the difference between the computed temporal response function and the template temporal response function.
