Temporal-spatial processing of a single speech reflection in normal-hearing and hearing-impaired listeners

Reflections and reverberation considerably affect speech recognition in rooms. Early reflections of the speech signal have mostly been found to enhance speech intelligibility [1, 2, 3, 4], while late reflections can have detrimental effects [4, 5]. A better understanding of the mechanisms underlying speech perception in noisy and reverberant conditions can be important for various practical investigations, e.g., the improvement of prediction models to be used in room design, de-reverberation and noise suppression algorithms, or the optimization of PA systems and loudspeakers configurations in rooms.
