在音高比较任务中估计频谱加权函数，以评估各个谐波对听众音高判断的相对影响。刺激是由前 12 个分量组成的准谐波复音，基频范围为 100 至 800 Hz。在每次刺激呈现时，每个谐波的频率都会发生少量随机抖动。每个谐波的感知权重计算为听众的二进制响应与该谐波的频率抖动之间的相关系数。虽然总体上目前的结果与之前的结果一致，显示了几种低阶谐波的主导作用，但在细节上存在差异。之前的一些报告认为，无论频率如何，主要谐波都具有固定的谐波等级，与此相反，当前的结果表明，主要谐波最好描述为接近 600 Hz 的固定绝对频率。 (C) 2000 年美国声学学会。 [S0001-4966(00)00102-8]。
Spectral weighting functions were estimated in a pitch-comparison task to assess the relative influence of individual harmonics on listeners' pitch judgment. The stimuli were quasi-harmonic complex tones composed of the first 12 components, with fundamental frequencies ranging from 100 to 800 Hz. On each stimulus presentation the frequency of each harmonic was randomly jittered by a small amount. The perceptual weight for each harmonic was calculated as the correlation coefficient between the binary responses of the listener and the frequency jitters for that harmonic. Although in general the present results conform to previous ones showing the predominant role of several low-ranked harmonics, discrepancies exist in details. Contrary to some previous reports that the dominant harmonics were of fixed harmonic ranks regardless of their frequencies, the current results showed that the dominant harmonics were best described as close to a fixed absolute frequency of 600 Hz.
