[Auditory processing and high frequency audiometry in students of São Paulo].

BACKGROUND Auditory processing and auditory sensibility to high Frequency sounds. AIM To characterize the localization processes, temporal ordering, hearing patterns and detection of high frequency sounds, looking for possible relations between these factors. METHOD 32 hearing fourth grade students, born in city of São Paulo, were submitted to: a simplified evaluation of the auditory processing; duration pattern test; high frequency audiometry. RESULTS Three (9,4%) individuals presented auditory processing disorder (APD) and in one of them there was the coexistence of lower hearing thresholds in high frequency audiometry. CONCLUSION APD associated to an auditory sensibility loss in high frequencies should be further investigated.
