Characterization of the performance of brazilian adolescents in the Pitch Pattern Sequence (PPS) test developed by Auditec®

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.【摘要】目的：考察巴西青少年在音调序列测试（Pitch Pattern Sequence, PPS）中的表现，并将测试结果与Auditec®标准参考值进行对比分析。 方法：本研究纳入26名就读于中小学、年龄介于12至18岁的两性青少年作为研究对象。纳入标准如下：a) 外耳道视检无异常改变；b) 双耳听阈处于正常范围，即双耳听阈值均≤25dBHL；c) 双耳鼓室图均为A型曲线；d) 双耳在500Hz、1000Hz及2000Hz频率下均可引出对侧声反射，且根据听觉行为量表（Scale of Auditory Behaviors, SAB）评定的听觉行为得分≥46分。对符合上述纳入标准的青少年，以双耳给声、50dBSL的强度施测Auditec®版音调序列测试（PPS），所得结果采用描述性与推断性统计方法进行分析。 结果：统计分析显示，巴西受试者完成PPS测试后得到的平均得分88.10%，与Auditec®建议的标准参考值（均值为96%）进行对比时，仅该均值比较存在统计学显著性。 结论：本研究结果表明，巴西人群施测Auditec®版PPS所得结果与国际文献报道的同类结果具有相似性。
