Abstract

Objective: The upper limit of sensitivity to binaural temporal fine structure (TFS) is around 1400 Hz. Higher values have been reported when keeping interaural phase differences fixed and varying the frequency adaptively, as in the adaptive-frequency TFS test [TFS-AF, Füllgrabe et al., Int J Audiol, 56, 926-935]. The probability of TFS-AF thresholds exceeding 1400 Hz, and the influence of age and hearing threshold were assessed.

Design and study sample: TFS-AF thresholds from 277 participants across five studies were re-analysed as a function of Age, low-frequency pure-tone average threshold (PTL; 250, 500, 1000 and 2000 Hz), and high-frequency pure-tone average threshold (PTH; 6000 and 8000 Hz). The 95% confidence intervals on TFS-AF thresholds were computed. The effects of Age and Hearing threshold on the TFS-AF thresholds were assessed using a multiple-regression model.

Results: The bootstrapped 95% confidence interval for this dataset around the median was 1030 to 1122 Hz, similar to that predicted by Monte Carlo simulation. This range was affected by Age and PTL. Regression modelling showed that the occurrence rate of TFS-AF thresholds exceeding 1400 Hz increased with younger Age and better PTL.

Conclusions: TFS-AF thresholds exceeding 1400 Hz are more likely for lower ages and better hearing thresholds.

年龄和听力损失对使用 TFS-AF 测试测量的阈值的影响。

目的：双耳时间精细结构（TFS）的灵敏度上限约为 1400 赫兹。据报道，在保持耳间相位差固定并自适应改变频率的情况下（如自适应频率 TFS 测试 [TFS-AF, Füllgrabe 等人，Int J Audiol, 56, 926-935]），该值会更高。研究评估了 TFS-AF 阈值超过 1400 Hz 的概率，以及年龄和听力阈值的影响：重新分析了五项研究中 277 名参与者的 TFS-AF 阈值与年龄、低频纯音平均阈值（PTL；250、500、1000 和 2000 Hz）和高频纯音平均阈值（PTH；6000 和 8000 Hz）的关系。计算了TFS-AF阈值的95%置信区间。使用多元回归模型评估了年龄和听阈对 TFS-AF 阈值的影响：该数据集围绕中位数的自引导 95% 置信区间为 1030 至 1122 Hz，与蒙特卡罗模拟预测的相似。这一范围受到年龄和 PTL 的影响。回归模型显示，TFS-AF阈值超过 1400 Hz 的发生率随着年龄的增长和 PTL 的改善而增加：结论：年龄越小、听力阈值越高，TFS-AF阈值超过 1400 Hz 的可能性越大。
