ABSTRACT
Objective This study was aimed at investigating the ability of temporal gap detection (TGD) in listeners with auditory neuropathy spectrum disorder (ANSD ) .Methods The temporal gap detection thresholds were measured for subjects using a TGD program developed by University of California ,Irvine .Three groups of subjects were recruited in this study ,including 12 subjects with normal hearing ,12 subjects with sensorineural hearing loss (SNHL) ,and 15 subjects with ANSD .The differences of TGD thresholds among the three groups of subjects were analyzed using a one - sample ANOVA method .Results No significant difference of the TGD thresh‐old was observed between two ears for all the subjects .The mean and standard deviation of the gap - detection threshold for both ears was about 3 .9 ± 1 .1 ms ,3 .6 ± 1 .1 ms ,and 13 .7 ± 9 .9 ms for normal - hearing subjects , subjects with SNHL ,and subjects with ANSD ,respectively .The TGD threshold in subjects with ANSD was sig‐nificantly higher than those of in normal hearing group (P< 0 .01) and SNHL group (P< 0 .01) ,while no signifi‐cant difference was found in TGD thresholds between normal - hearing subjects and subjects with SNHL .Conclusion For listeners with auditory neuropathy spectrum disorder ,their ability to resolve temporal information was de‐graded with a large individual variability .
