Time resolution hearing skill is the minimum time necessary to solve acoustic events, which is fundamental for speech understanding, and which may be assessed by gap-detection tests, such as the Gaps-in-noise test (GIN).
the purpose of this study was to verify the performance of time processing ability in children with no hearing and/or education difficulties by applying the GIN test in both genders and ages from 8 to 10 years.
a prospective cross-sectional contemporary cohort.
The GIN test was applied to 75 school-aged children separated into three groups by age.
The findings showed no statistical differences among age groups or ears. Males had slightly better responses than females on the percentage of correct responses only.
The gap threshold and percentage of correct responses were calculated regardless of the ear, gender or age, and were respectively 4.7ms and 73.6%. Based on a 95% confidence interval, the cut-off criterion for normal and abnormal performance was 6.1ms for the mean gap detection threshold and 60% for the percentage of correct responses.
时间分辨听力技能是解决声音事件所需的最短时间，这对于言语理解至关重要，可通过间隙检测测试（如噪声间隙测试[GIN]）进行评估。
本研究旨在通过在 8 至 10 岁的男女和年龄组中应用 GIN 测试，来验证无听力和/或教育困难的儿童的时间处理能力表现。
前瞻性的横断当代队列研究。
将 GIN 测试应用于 75 名学龄儿童，根据年龄分为三组。
结果显示，年龄组或耳朵之间没有统计学差异。仅在正确反应的百分比上，男性的反应略好于女性。
无论耳朵、性别或年龄如何，均计算了间隙阈值和正确反应的百分比，分别为 4.7ms 和 73.6%。基于 95%置信区间，正常和异常表现的截止标准为平均间隙检测阈值为 6.1ms，正确反应百分比为 60%。
