以高频率分辨率测量的听力图通常在正常听力的听众中显示高达15 dB的准周期性波纹。安静时阈值的这种精细结构通常与耳蜗中的活动过程相关联。因此，在文献中将其缺失作为耳蜗脆弱性的指标进行了讨论。为了实现阈值精细结构的快速检测和客观量化，本文介绍并评估了两种仪器：（1）用于测量精细结构的高分辨率跟踪方法（“FINESS”），以及（2）自动精细结构检测器（“FINESS检测器”）。该方法的可靠性，其准确性，并与频率的漂移进行测试，通过分析测试/重测实验，并通过比较所测得的阈值从参考程序的结果。结果表明，FINESS和FINESS检测器是合适的技术，用于测量和检测阈值精细结构，这可能有助于进一步研究精细结构是否是检测早期听力损失的敏感工具。
Audiograms measured with a high frequency resolution often show quasi-periodic ripples of up to 15dB in normal-hearing listeners. This fine structure of the threshold in quiet is commonly associated with the active processes in the cochlea. Therefore its absence is discussed in the literature as an indicator of cochlear vulnerability. In order to enable a quick detection and an objective quantification of threshold fine structure, two instruments are introduced and evaluated in this article: (1) a high-resolution tracking method for measuring fine structure (‘FINESS’), and (2) an automatic fine-structure detector (‘FINESS-detector’). The method is tested on 22 subjects for its reliability, its accuracy, and drifts with frequency by analysing test/retest experiments and by comparing the measured thresholds to results from a reference procedure. The results indicate that FINESS and the FINESS-detector are suitable techniques for the measurement and detection of threshold fine structure that may help to investigate further into whether fine structure is a sensitive tool for the detection of an early hearing loss.
