INTRODUCTION: Tinnitus is an individual’s auditory perception when there is no external sound source. Some individuals have attention deficits as a result of tinnitus. A good auditory processing performance depends on cognitive factors such as memory, learning and attention integrity. Considering that tinnitus affects attention, it is possible that individuals with tinnitus could have also auditory processing disorder. OBJECTIVE: Evaluate and compare the auditory abilities of temporal resolution and selective attention of adults with normal audiometry, with and without tinnitus and verify if it’s correlated with the tinnitus handicap, pitch and loudness. METHOD: Students of Federal University of Sao Paulo where selected and divided in two groups: study and comparison. The inclusion criteria for both groups where: age between 19 and 44 years old, male or female with normal hearing. For the study group, the individuals should have tinnitus complain in one or both ears. Both groups had their audition and auditory processing assessed. After the assessments, the data were analyzed and compared between groups by descriptive statistics, parametric tests when there was a normal distribution and not parametric when the distribution was normal. RESULTS: In the Speech in noise test, the mean value of correct answers for the group without tinnitus was 96.5% on the right ear and 96.4% on the left, and for the tinnitus group was 98.3% on the right and 97.1% on the left. In the Dichotic digits test, the mean value of correct answers for the group without tinnitus was 99.5% on the right ear and 99.4% on the left, and for the tinnitus group was 99.3% on the right and left ears. The mean gap detection threshold for the without tinnitus group in the assessment of the Gaps in noise test was 4.7 msec for the right ear and 5.1 msec for the left and for the tinnitus group was 4.7 msec for the right and 4.8 msec for the left. There were no statistical significant differences between groups when comparing all the tests results. CONCLUSIONS: The individuals with and without tinnitus had the same performance on the assessment of auditory processing tests that evaluate selective attention and temporal resolution auditory abilities
