【 摘 要 】

INTRODUCTION:Dichotic listening tests should be used in local languages and adapted for the population.OBJECTIVE: Standardize the Brazilian Portuguese version of the Dichotic Sentence Identification test in normal listeners, comparing the performance for age and ear.METHODS: This prospective study included 200 normal listeners divided into four groups according to age: 13-19 years (GI), 20-29 years (GII), 30-39 years (GIII), and 40-49 years (GIV). The Dichotic Sentence Identification was applied in four stages: training, binaural integration and directed sound from right and left.RESULTS: Better results for the right ear were observed in the stages of binaural integration in all assessed groups. There was a negative correlation between age and percentage of correct responses in both ears for free report and training. The worst performance in all stages of the test was observed for the age group 40-49 years old.CONCLUSIONS: Reference values for the Brazilian Portuguese version of the Dichotic Sentence Identification test in normal listeners aged 13-49 years were established according to age, ear, and test stage; they should be used as benchmarks when evaluating individuals with these characteristics.
