ABSTRACT Purpose: to characterize the performance of Brazilian adolescents in the Pitch Pattern Sequence (PPS) test and compare the results with Auditec® normative values. Methods: 26 adolescents enrolled in elementary or secondary education, of both sexes, and between 12 and 18 years, participated in the study. The inclusion criteria adopted were: a) no alterations in the visual inspection of the external acoustic meatus; b) hearing thresholds within the normal range for both ears, that is, values equal to or lower than 25dBHL; c) bilateral type “A” tympanometric curve, d) presence of acoustic reflex, contralateral mode, in the frequencies of 500, 1000 and 2000Hz, in both ears, typical auditory behavior according to the Scale of Auditory Behaviors (SAB) or greater than 46 points. For adolescents, who met the inclusion criteria, the PPS (Auditec® version) was applied, binaurally, at 50dBSL. The findings were analyzed in a descriptive and inferential manner. Results: statistical analysis showed significance only for the comparison of the mean value of 88.10%, a result obtained in the PPS performed by Brazilians, when compared to the normative value (included) suggested by Auditec®, in which the mean was 96%. Conclusion: the findings of this study demonstrated that the values obtained in the PPS, Auditec® version, in the Brazilian population, were similar to those presented in the international literature. RESUMO Objetivo: caracterizar o desempenho de adolescentes brasileiros no Teste de Padrão de Frequência e, comparar os resultados com os valores normativos da Auditec®. Métodos: 26 adolescentes matriculados no ensino fundamental ou médio, de ambos os sexos, e com idade entre 12 e 18 anos participaram do estudo. Adotaram-se como critérios de inclusão: a) sem alterações na inspeção visual do meato acústico externo; b) limiares audiométricos dentro dos padrões de normalidade em ambas as orelhas, ou seja, valores iguais ou inferiores a 25dBNA; c) curva timpanométrica do tipo “A” bilateral, d) presença de reflexo acústico, modo contralateral, nas frequências de 500, 1000 e 2000Hz, em ambas orelhas, comportamento auditivo típico de acordo com o questionário Scale of Auditory Behaviors(SAB) (pontuação igual ou superior a 46 pontos). Para os adolescentes que atenderam ao critério de inclusão foi aplicado o Teste de Padrão de Frequência (versão Auditec®), de forma binaural, em 50dBNS. Os achados foram analisados de forma descritiva e inferencial. Resultados: a anál
