Sensorineural and auditory neuropathy hearing losses impair opposite spectral and temporal abilities

Evidence

Studies have shown that listeners with SNHL may have reduced frequency resolution (Kluk and Moore 2006 ), but probably normal temporal resolution (Glasberg et al. 1987 ). In contrast, listeners with ANSD may have a dramatically impaired ability for processing temporal information (Narne 2013 ), while their frequency selectivity may be close to normal (Vinay and Moore 2007 ). To clarify whether it is the deficit in temporal resolution or frequency resolution that may lead to more detrimental effects on FS processing in lexical tone perception, we also measured the frequency resolution using the mean Q10 dB values of the psychophysical tuning curves (PTCs), and the temporal resolution using the temporal gap detection (TGD) threshold for the SNHL and ANSD subjects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3380
