Abstract

A device for generating a filtered activity pattern based on a first activity pattern at an auditory model of a first ear and a second activity pattern at an auditory model of a second ear includes an identifier for identifying a first trajectory in the first activity pattern and a second trajectory in the second activity pattern which are associated with the same sound event. The device further includes a determiner for determining whether the two trajectories are associated with a sound event of a useful sound source. The device further includes a filter for filtering the first activity pattern or the second activity pattern based on a result of determining whether a trajectory is associated with a sound event of the useful sound source.
