Abstract

Tinnitus is a symptom defined as a perception of sound that is responsible for negative consequences in a significant amount of population and, can be considered a public health issue. The aim of the present study was to evaluate the effects of auditory training as an intervention tool to the subjects with tinnitus regarding the tinnitus severity and psychoacoustic characteristics. The patients records were analyzed to select adults with tinnitus and bilateral sensorineural hearing loss, level from mild to moderate and adults without hearing loss were selected. The Tinnitus Handicap Inventory (THI), the Visual Analogue Scale (VAS), the Minimum Masking Level (MML), high frequencies audiometry, psychoacoustics measures (pith and loudness matching) and, auditory training were performed for all the selected subjects. The subjects were instructed to perform the TA in the Portal Afinando o Cérebro at home for at least 20 minutes and for the maximum of 30 minutes, during five consecutive days in the week (once a day) and, a total of four weeks. Twenty-three patients were included in the present study and were allocated in two groups (G1 and G2). Fifteen patients were included in the G1 with no hearing loss (WHO) and they performed the auditory training. The G2 was composed by 8 patients with bilateral sensorineural hearing loss, fitted with behind-the-ear hearing aids following the specific needs of each patient and after the fitting the patients began the auditory training at home. The mean age of G1 was 51,73±13,11 and 72,13±8,94 for G2. Only the G2 founds were statistically significant in the assessment with THI and VAS, pre and post intervention. Regarding the psychoacoustic measures were found significant differences in the comparison between the groups. The present study found specific significant differences and the G2 presented the most positive results in the assessment with THI and VAS, pre and post auditory training and, the psychoacoustic measures did not show significant differences regarding the intervention with auditory training. Hence, the differences found were not enough to made a categorical statement about the benefits of TA, when used as intervention for tinnitus. (AU)
