Abstract

Purpose: To establish the standard criteria for the Gaps-in-Noise (GIN) test in 9-year-old normal-hearing children; to obtain the mean gap detection thresholds; and to verify the influence of the variables gender and ear on the gap detection thresholds.

Methods: Forty normal-hearing individuals, 20 male and 20 female, with ages ranging from 9 years to 9 years and 11 months, were evaluated. The procedures performed were: anamnesis, audiological evaluation, acoustic immittance measures (tympanometry and acoustic reflex), Dichotic Digits Test, and GIN test. The results obtained were statistically analyzed.

Results: The results revealed similar performance of right and left ears in the population studied. There was also no difference regarding the variable gender. In the subjects evaluated, the mean gap detection thresholds were 4.4 ms for the right ear, and 4.2 ms for the left ear.

Conclusion: The values obtained for right and left ear, as well as their standard deviations, can be used as standard criteria for 9-year-old children, regardless of ear or gender.

噪声间隙测试:9岁正常听力儿童的间隙检测阈值。

目的:建立9岁正常听力儿童噪声间隙(GIN)测试标准;得到平均间隙检测阈值;并验证变量性别和耳朵对间隙检测阈值的影响。方法:选取听力正常者40例，男20例，女20例，年龄9 ~ 9岁11个月。检查程序包括:记忆、听力学评估、声阻抗测量(鼓室测量和声反射)、双指测试和GIN测试。对所得结果进行统计学分析。结果:结果显示，在研究人群中，右耳和左耳的表现相似。在可变性别方面也没有差异。在被评估的受试者中，右耳的平均间隙检测阈值为4.4 ms，左耳为4.2 ms。结论:获得的右耳和左耳的数值及其标准差可作为9岁儿童的标准标准，不论耳朵或性别。
