Individual listeners differ in which abilities support their speech perception per situation

Evidence

Taken together, it is thought that sensorineural hearing loss does not yield large deficits in either gap detection or amplitude modulation detection when audibility and bandwidth are taken into account. Across the studies conducted, however, one hallmark is a wide range of performance by listeners with hearing loss (Hall, Grose, Buss, & Hatch, 1998). Gap detection thresholds can be very elevated in some listeners with hearing loss, suggesting that a small subset of listeners may have true deficits in temporal processing. Because these deficits can exist, we should not treat listeners with hearing loss as a homogenous group in their perceptual abilities. We must consider that some listeners with hearing loss experience temporal processing deficits, even if many do not. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1092 (#expands, via linked claim)
