ABSTRACT
This study aimed at investigating the ability of temporal resolution in Korean adult population using Gaps-in-Noise (GIN) test, and examining the clinical feasibility for the diagnosis of auditory processing disorder. For the GIN test, mean approximated gap detection thresholds (A.th.) and percent correct responses were obtained. The reliability of the GIN was also tested. Subjects were 40 adults (20 males and 20 females) in their 20 years with normal hearing sensitivity. The results of this study are as follows. First, the results of GIN test showed that the mean A.th. were 4.95 (± 1.15) and 5.05 (± 1.18) msec for the right and left ears, respectively and the percent correct scores were 72.08% (± 7.13) and 72.13% (± 7.72) for the right and left ears, respectively. There were no significant differences between ears and genders. Furthermore, it is revealed that GIN is a high reliability test. The inter-list consistency indicated an equivalency between four GIN lists showed no significant difference. These findings in this study are similar to the results of the studies performed to other language population. Results of the study support that temporal resolution abilities measured by GIN may also be clinically feasible for Korean adult population.
