Aging and hearing impairment raise thresholds for temporal and level-based lateralization cues.

Evidence

For the low-frequency stimulus (the upper row of panels in Fig. 1 ), a one-way analysis of variance indicated a statistically significant effect of listener group in the TIME task only. Subsequent pair-wise comparisons indicated higher thresholds for the ENH and EHI listeners than for the YNH listeners. For the high-frequency stimulus (the lower rows of panels), a significant effect of listener group was found in the ITD, TIME , and LEVEL tasks. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1063
