| Abstract | |
The Gaps-in-Noise (GIN) test assesses the auditory temporal resolution skill. Studies have described the GIN test an instrument of easy application and with good sensitivity and specificity. To compare the results of the GIN test in normal listeners with and without tinnitus and to correlate the obtained results with pure tone thresholds and age. Hearing tests were performed in 44 subjects (hearing threshold up to 25 dB HL in the frequencies of 0.25 to 8 kHz). Two groups were considered for comparison: the Control Group with 23 subjects, 8 men and 15 women, aged between 22-40 (mean 29.7), and the Research Group with 18 tinnitus patients, 3 men and 15 women, aged between 21-45 (mean 31.3). All subjects underwent pure tone audiometry, speech tests, acoustic immittance measurements and the GIN test. For the statistical analysis, the significance level of 0.05 was adopted. Considering pure tone audiometry, the overall mean for hearing thresholds was significantly higher for the Research Group when compared to the Control Group (p = 0.001). The comparison between the groups for the performance in the GIN test indicated that the Control Group detected gaps with a shorter time interval than the Research Group (p < 0.001). There was no correlation between the age of the subjects and the level of the GIN test. The GIN test identified deficit in the hearing skill of temporal resolution in patients with tinnitus. In the studied age group (21 to 45 years) there was no correlation between age and the results obtained in the GIN test. (AU) | |
