- Abstract
Auditory temporal resolution is the main feature of speech processing abilities. Gap in noise test (GIN) is the one of the new tests for assessing auditory temporal resolution. This study aimed to compare temporal resolution ability of subjects who wear cochlear implant (CI) and normal-hearing listeners. In this cross sectional study, GIN was performed on 9 postlingually cochlear implanted patients with mean age of 31.77±6.6 and 17 controls with mean age of 32.76±6.5 years. Following a training period (8 sessions on the average), the cochlear implant users were reevaluated by the same test. Data were analyzed by independent and paired t-test using SPSS software version 18. There was significant difference in approximate threshold and percent of corrected answers between cochlear implant users and normal-hearing controls (p<0.05). The mean approximate threshold and percent of corrected answers of cochlear implant users after training period, was significantly improved (p<0.05). The results demonstrated that patients with cochlear implant have some ability of auditory temporal resolution, and that this ability may be improved by regular training.
