Abstract
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.
Highlights
Auditory processing is fundamental for understanding the information that is received aurally, and for this process to occur properly, the set of abilities that constitute this processing must be intact.For the auditory information to be processed, it is necessary that the auditory abilities involved in this process be integrated, such as: sound detection and localization, speech recognition, figure-ground for verbal and non-verbal sounds, auditory closure synthesis ability, simple temporal ordering, complex temporal ordering, temporal pattern recognition, and the ability to discriminate sounds that includes temporal resolution, frequency and duration[1,2].Among these abilities, it is important to note that temporal processing is afundamental component for most auditory abilities
The temporal processing is not restricted to the perception of intervals between the stimuli, but it is related to the short-term auditory memory, responsible for storing recent information for a short period of time[7,8] and it includes temporal resolution, temporal integration, temporal masking and temporal ordering abilities[9]
Results of this research were organized in order to analyze the performance of Brazilian adolescents in the Pitch Pattern Sequence Test Auditec® version
