Auditory neuropathy subjects preserved normal cochlear frequency resolution despite temporal deficits

Evidence

Since no significant differences were found between the Q10 dB values at 500 and 1000 Hz, the Q10 dB values averaged across the two test frequencies are plotted in Fig. 2 . Statistically significant differences of the Q10 dB values were found between the subjects with NH and those with SNHL and between the subjects with ANSD and those with SNHL, while no statistically significant differences were present between the subjects with NH and those with ANSD. This indicates that a majority of the subjects with ANSD showed close-to-normal frequency resolution, whereas the SNHL subjects had poor frequency resolution in the present study. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3380
