Abstract

A hearing assistance system comprises an input unit for providing electric input sound signals u i , each representing sound signals U; from a multitude n u of sound sources S i , an electroencephalography (EEG) system for recording activity of the auditory system of the user's brain and providing a multitude ny of EEG signals y j , and a source selection processing unit receiving said electric input sound signals u i and said EEG signals y j , and in dependence thereof configured to provide a source selection signal S x indicative of the sound source S x 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 S x based on the cost functions obtained for said multitude of sound sources.
