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.
