The audiogram cannot predict which hearing-impaired listeners have temporal processing deficits

Evidence

We can conclude from these studies that while many listeners with SNHL do not experience deficits in temporal processing when measured using gap detection, some listeners likely experience temporal processing deficits associated with SNHL. The audiogram has not been a reliable indicator of who may or may not experience such deficits. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1088
