Introduction: Tinnitus may be defined as the conscious perception of sound or noise in the absence of external acoustic stimulation. Considering the damage caused by tinnitus, the lack of effective and efficient treatment for all cases of tinnitus and further the difficulty of using the Tinnitus Retraining Therapy - TRT, as it is costly and overlong, it is evident the need of proposing alternatives to rehabilitation of people with such problem. Thus, the hypothesis of the present study is that the formal auditory training may lead to reorganization in the auditory system of patients with tinnitus, promoting a decrease in the symptoms, due to the strengthening of synapses in the auditory pathway, and further a best synchronism of the fire neurons involved in auditory processing. This modification would be observed by assessing behavioral and electrophysiological through the THI questionnaire - Tinnitus handcap Inventory. Objective: The aim of this study was to investigate the effect of a formal auditory training program on patients with tinnitus perception of this symptom. Method: The study included 13 subjects with tinnitus who were divided into two randomized groups, six in the Study Group (SG) and seven in the control group (CG). All subjects performed the following procedures: interview; tonal and vocal audiometry, tympanometry, electrophysiological assessment of hearing; acuphenometry; application of THI; auditory processing assessment reduced (GIN - Gaps In Noise Test Pattern Frequency and Speech in Noise). After such procedures all subjects went through the auditory training according to each group. The experimental group was subjected to formal auditory training, performed in an acoustic cabin for aproximately 40 minutes in eight sessions, once a week; the activities were mainly focused on both temporal auditory skills and auditory attention. The CG underwent eight sessions of visual training that lasted 40 minutes each, held once a week, with activities such as crossword puzzles, word search puzzles, play Sudoku and the 7 mistakes. For statistical analysis we used the Wilcoxon matched pairs test, technical models for repeated measures and multiple linear models, with a significance level of 0.05. Results: In the characterization of the groups, there was found no statistically significant differences for the variables gender, age, pitch and loudness of tinnitus as well as hearing thresholds in conventional audiometry and high frequencies. Comparisons were performed between groups, pre and post auditory training and visual, electrophysiological testing, behavioral and THI. Data analysis, using the model of repeated measures for each variable, showed no statistically significant differences between groups when comparing the situations before and after training for any of the evaluations. Conclusion: The present study aimed to verify the effect of an auditory training program in patients with tinnitus, that is, in their perception of this symptom. Our findings showed no statistically significant differences before and after the auditory training and training placebo between the groups (CG and EG) and also for the electrophysiological findings, the behavioral assessment of auditory processing and THI (AU)
