The present study evaluated the effects of advancing age and sensorineural hearing loss (SNHL) on approximate temporal gap detection thresholds obtained from the Gaps-in-Noise (GIN; Musiek et al., 2005) test.
Approximate thresholds from the GIN test were compared among 3 groups of participants (older adults with SNHL, older adults with essentially normal hearing, and young adults with normal hearing). Analyses of variance and regression modeling were used to determine the effect of age and audibility on GIN performance. Comparisons of thresholds obtained from the 4 test lists of the GIN were also conducted.
Approximate gap thresholds differed significantly across all groups, with the poorest thresholds found in older adults with SNHL and with the best thresholds found in young adults with normal hearing. The strongest predictor of decreases in GIN performance was increased Audibility Index score, but a significant independent effect of age was also documented. Test list influenced GIN performance only in the group of young adults with normal hearing.
The GIN test is a promising clinical measure of temporal resolution. Findings from the present study suggest that age and audibility influence GIN performance and may affect test analysis and interpretation with published normative data.
本研究评估了年龄增长和感音神经性听力损失（SNHL）对通过噪声间隙（GIN；Musiek等人，2005年）测试获得的近似时间间隙检测阈值的影响。
比较了3组参与者（患有SNHL的老年人、听力基本正常的老年人和听力正常的年轻人）的GIN测试近似阈值。采用方差分析和回归模型来确定年龄和可听度对GIN测试表现的影响。还对从GIN的4个测试列表中获得的阈值进行了比较。
所有组的近似间隙阈值存在显著差异，患有SNHL的老年人阈值最差，听力正常的年轻人阈值最佳。GIN测试表现下降的最强预测因素是可听度指数得分增加，但年龄的显著独立影响也得到了记录。测试列表仅在听力正常的年轻人群体中影响GIN测试表现。
GIN测试是一种很有前景的时间分辨率临床测量方法。本研究结果表明，年龄和可听度会影响GIN测试表现，可能会影响使用已发表的标准数据进行的测试分析和解释。
