PURPOSE: The aims of this study are the development of an auditory processing test with musical stimuli in dichotic tasks, the characterization of the performance of normal hearing subjects and the comparison between the results and those in the Digits Dichotic Test (TDD). METHODS: The auditory processing test with musical stimuli was elaborated with harmonic digits. The test was denominated Harmonic Pattern Dichotic Digits Test (TDDH) and comprised biaural integration and two stages of biaural separation (left/right), each one with 20 items made up of four harmonic digits. It was applied in 40 individuals of both sexes. They were all adults, their ages ranged from 19 to 52 years old and they spoke Brazilian Portuguese. RESULTS: The results were compared to results of the TDD applied in the same individuals. The individuals had approximately 99% success in all the stages, their performance was higher than the one observed in the TDD - stages of biaural separation. CONCLUSION: We believe that the test elaborated for this study showed applicability in normal hearing individuals. The use of musical stimuli seems to make the performance of individuals easier than the dichotic verbal tests.
