用高频分辨率测量的听力阈值显示出一种称为阈值精细结构(或微结构)的准周期变化。在12名受试者中，研究了这种精细结构对一系列刺激水平上的响度知觉的影响。使用了三种不同的方法。使用响度匹配范式测量了8名受试者的个体听力阈值和等响度轮廓。此外，使用响度匹配范式，从五个受试者的听力阈值中观察到与个体最小或最大值相关的频率的正弦波的响度增长。在低水平下，响度的增长取决于测试或参考音调频率在阈值精细结构中的位置。当将相同的测试音调与两个不同的参考音进行比较时，响度增长的斜率相差0.2分贝/分贝，即，刺激中每10分贝变化响度增长2分贝。最后，在没有参考音调的情况下，使用绝对响度标度作为直接标度技术来测量相同五个受试者的响度增长，而不是响度匹配程序。总体而言，在高达40dBSPL的刺激水平下，听力阈值精细结构对正弦信号响度感知的影响是可观察到的--与所使用的程序无关。讨论了细微结构对响度测量和其他心理声学实验的可能意义，例如在阈值最小值和最大值范围内的不同压缩。
Hearing thresholds measured with high-frequency resolution show a quasiperiodic change in level called threshold fine structure (or microstructure). The effect of this fine structure on loudness perception over a range of stimulus levels was investigated in 12 subjects. Three different approaches were used. Individual hearing thresholds and equal loudness contours were measured in eight subjects using loudness-matching paradigms. In addition, the loudness growth of sinusoids was observed at frequencies associated with individual minima or maxima in the hearing threshold from five subjects using a loudness-matching paradigm. At low levels, loudness growth depended on the position of the test- or reference-tone frequency within the threshold fine structure. The slope of loudness growth differs by 0.2 dB/dB when an identical test tone is compared with two different reference tones, i.e., a difference in loudness growth of 2 dB per 10-dB change in stimulus. Finally, loudness growth was measured for the same five subjects using categorical loudness scaling as a direct-scaling technique with no reference tone instead of the loudness-matching procedures. Overall, an influence of hearing-threshold fine structure on loudness perception of sinusoids was observable for stimulus levels up to 40 dB SPL--independent of the procedure used. Possible implications of fine structure for loudness measurements and other psychoacoustic experiments, such as different compression within threshold minima and maxima, are discussed.
