Frequency discrimination deficits depend on temporal fine structure, not excitation patterns

Evidence

Many studies have shown that cochlear hearing loss is associated with larger than normal DLFs. For a review, see Moore ( 2014 ). However, in most studies the hearing-impaired subjects were older than the normal-hearing subjects, so some (but probably not all) of the effects of hearing loss may have been due to age. DLFs for hearing-impaired subjects are not correlated with measures of frequency selectivity (Tyler et al. 1983 ; Moore and Peters 1992 ), confirming that DLFs depend on TFS information and not excitation-pattern information. — Dijk, Pim van, Physiology, Psychoacoustics and…, 812
