Hearing-impaired listeners retain partial sensitivity to inherent noise fluctuations, unlike CI users
Evidence
Overall, the HI group showed smaller-than-normal differences between maskers with and without inherent fluctuations. This loss of sensitivity to inherent fluctuations was particularly apparent in the vocoded conditions (Fig. 3 ; lower right panel). However, in contrast to earlier results from CI users (Oxenham and Kreft 2014 ), some differences remained between conditions with and without inherent fluctuations, suggesting that the effects of poorer frequency selectivity are not as profound as for CI users. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2200
