1. System for assisting selective hearing, the system comprising:
a detector for detecting an audio source signal portion of one or more audio sources by using at least two received microphone signals of a hearing environment,
a position determiner for assigning position information to each of the one or more audio sources,
an audio type classifier for allocating an audio signal type to the audio source signal portion of each of the one or more audio sources,
a signal portion modifier for varying the audio source signal portion of at least one audio source of the one or more audio sources depending on the audio signal type of the audio source signal portion of the at least one audio source so as to acquire a modified audio signal portion of the at least one audio source, and
a signal generator for generating a plurality of binaural room impulse responses for each audio source of the one or more audio sources depending on the position information of this audio source and an orientation of a user's head, and for generating at least two loudspeaker signals depending on the plurality of the binaural room impulse responses and depending on the modified audio signal portion of the at least one audio source.
