Hearing loss extends internal masker persistence and shrinks duration benefits

Evidence

On the other hand, forward-masking experiments illustrate poorer temporal processing in listeners with SNHL. Listeners experience a reduced release from forward masking, in which the representation of the masker persists for a greater period of time than for normal-hearing listeners. Finally, these listeners also experience a reduction in temporal integration. Listeners with SNHL receive only very small benefits in detection ability from increasing stimulus duration. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1120
