A system and a corresponding method for assisting selective hearing are provided. The system includes 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. In addition, the system includes a position determiner for allocating position information to each of the one or more audio sources. In addition, the system includes an audio type classifier for assigning an audio source signal type to the audio source signal portion of each of the one or more audio sources. In addition, the system includes 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 obtain a modified audio signal portion of the at least one audio source. In addition, the system includes a signal generator.

System and method for assisting selective hearing

A device for determining room-optimized transfer functions for a listening room serving for room-optimized post-processing of audio signals in spatial production, is configured to analyze room acoustics of the listening room and to determine, based on the analysis of the room acoustics, the room-optimized transfer functions for the listening room where the spatial reproduction by means of a binaural close-range sound transducer is to take place. The spatial reproduction of the audio signals by means of the binaural close-range sound transducer may then be emulated using known head-related transfer functions und using the room-optimized transfer functions, wherein a room to be synthesized may be emulated based on the head-related transfer functions, and wherein the listening room may be emulated based on the room-optimized transfer functions.
