gap detection in 11 and 12-year-old children.
to investigate temporal resolution through the Gap in Noise test in children of 11 and 12 years in order to establish criteria of normal development.
participants were 92 children, with ages of 11 and 12 years, enrolled in elementary school, with no evidences of otologic, and/or neurologic, and/or cognitive disorders, as well as with no history of learning difficulties or school failure. Besides that, participants' hearing thresholds were within normal limits and their verbal recognition in the dichotic test of digits was equal or superior to 95% of hits. All were submitted to the Gap in Noise test. The statistical analysis was performed by non-parametric tests with significance level of 0.05 (5%).
the average of the gap thresholds was 5.05 ms, and the average percentage of correct answers was 71.70%. There was no significant statistical difference between the responses by age (eleven and twelve years), by ear (right and left), by gender (male and female). However, when comparing the tests, it was observed that the 1st test showed a higher percentage of identifications of gap, statistically significant than the 2nd test.
in 78.27% of the population of this study, the gap thresholds were up to 5 ms, response recommended as normality reference for the age group searched.
11岁和12岁儿童的间隙检测。
通过对11岁和12岁儿童进行噪声间隙测试来研究时间分辨率，以建立正常发育标准。
研究对象为92名11岁和12岁的小学生，他们没有耳科、神经科和/或认知障碍的证据，也没有学习困难或学业失败的病史。此外，参与者的听力阈值在正常范围内，并且他们在数字双耳测试中的言语识别率等于或高于95%的正确率。所有参与者均接受噪声间隙测试。采用非参数检验进行统计分析，显著性水平为0.05（5%）。
间隙阈值的平均值为5.05毫秒，正确答案的平均百分比为71.70%。年龄（11岁和12岁）、耳朵（右耳和左耳）、性别（男性和女性）之间的反应没有显著统计学差异。然而，在比较测试时，观察到第一次测试的间隙识别百分比更高，在统计学上显著高于第二次测试。
在本研究人群中，78.27%的人的间隙阈值高达5毫秒，该反应建议作为所研究年龄组的正常参考。
