Hearing-impaired listeners gain half or less benefit from longer stimulus durations
Evidence
Recall that temporal integration is the ability to take advantage of increases in stimulus duration to improve perception. Not surprisingly, temporal integration is also impacted by SNHL. Hall and Fernandes (1983) and Carlyon, Buus, and Florentine (1990) measured temporal integration in listeners with normal hearing and with SNHL and found that the benefit afforded by increasing the duration of the stimulus was about 1/2 or less for listeners with SNHL. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1112
