目的：越来越多的证据支持将量化时间精细结构（TFS）处理的感知测试纳入临床听力评估。许多任务已被用来评估TFS在实验室中，在很大程度上不同的刺激使用，以及判断是否需要单耳或双耳的TFS比较。本研究的目的是比较实验室测量的TFS列入电池的阈上听觉测试。一个子集的可用TFS任务的基础上选择的潜在的临床效用，并进行了评估，重点放在临床use.Method的特点：TFS措施复制的研究，证明临床效用。对11名听力正常的年轻听众进行了单耳、双耳和双耳分听测量。措施包括频率调制（FM）任务、谐波频移检测、耳间相位差（IFS-低频）、耳间时间差（ITD）、单耳间隙持续时间辨别以及有和无耳间相位差的噪音中的音调检测（N 0 S 0，N 0 STT）。数据与已发表的结果进行了比较，并与一致性和效率的度量进行了评估。没有证据表明与同质组一致的措施之间的预测关系。重复测试中最稳定的任务是TFS-低频、双耳分音和双耳两分音FM和N-0 S-TT。单耳和diotic FM有最低的标准化方差和最有效的占总测试时间的差异，其次是ITD.Conclusions：尽管刺激持续时间长，FM任务占主导地位的一致性和效率的比较。小的差异分离的两分任务FM，ITD和N 0 STT。在任务的程序优化之后的未来比较将评价损伤人群的临床效率。
Purpose: Growing evidence supports the inclusion of perceptual tests that quantify the processing of temporal fine structure (TFS) in clinical hearing assessment. Many tasks have been used to evaluate TFS in the laboratory that vary greatly in the stimuli used and whether the judgments require monaural or binaural comparisons of TFS. The purpose of this study was to compare laboratory measures of TFS for inclusion in a battery of suprathreshold auditory tests. A subset of available TFS tasks were selected on the basis of potential clinical utility and were evaluated using metrics that focus on characteristics important for clinical use.Method: TFS measures were implemented in replication of studies that demonstrated clinical utility. Monaural, diotic, and dichotic measures were evaluated in 11 young listeners with normal hearing. Measures included frequency modulation (FM) tasks, harmonic frequency shift detection, interaural phase difference (TFS-low frequency), interaural time difference (ITD), monaural gap duration discrimination, and tone detection in noise with and without a difference in interaural phase (N0S0, N0STT). Data were compared with published results and evaluated with metrics of consistency and efficiency.Results: Thresholds obtained were consistent with published data. There was no evidence of predictive relationships among the measures consistent with a homogenous group. The most stable tasks across repeated testing were TFS- low frequency, diotic and dichotic FM, and N-0 S-TT. Monaural and diotic FM had the lowest normalized variance and were the most efficient accounting for differences in total test duration, followed by ITD.Conclusions: Despite a long stimulus duration, FM tasks dominated comparisons of consistency and efficiency. Small differences separated the dichotic tasks FM, ITD, and N0STT. Future comparisons following procedural optimization of the tasks will evaluate clinical efficiency in populations with impairment.
