Listeners appear able to extract a residue pitch from high-frequency harmonics for which phase locking to the temporal fine structure is weak or absent. The present study investigated musical interval perception for high-frequency harmonic complex tones using the same stimuli as Lau, Mehta, and Oxenham [J. Neurosci. 37, 9013-9021 (2017)]. Nine young musically trained listeners with especially good high-frequency hearing adjusted various musical intervals using harmonic complex tones containing harmonics 6-10. The reference notes had fundamental frequencies (F0s) of 280 or 1400 Hz. Interval matches were possible, albeit markedly worse, even when all harmonic frequencies were above the presumed limit of phase locking. Matches showed significantly larger systematic errors and higher variability, and subjects required more trials to finish a match for the high than for the low F0. Additional absolute pitch judgments from one subject with absolute pitch, for complex tones containing harmonics 1-5 or 6-10 with a wide range of F0s, were perfect when the lowest frequency component was below about 7 kHz, but at least 50% of responses were incorrect when it was 8 kHz or higher. The results are discussed in terms of the possible effects of phase-locking information and familiarity with high-frequency stimuli on pitch.
听众似乎能够从高频谐波中提取残留音高，而对于这些高频谐波，与时间精细结构的锁相作用微弱或不存在。本研究使用与Lau、Mehta和Oxenham [《神经科学杂志》37, 9013 - 9021 (2017)]相同的刺激，研究了高频谐波复合音的音乐音程感知。九名经过音乐训练且高频听力特别好的年轻听众，使用包含谐波6 - 10的谐波复合音来调整各种音乐音程。参考音符的基频（F0）为280或1400 Hz。即使所有谐波频率都高于假定的锁相极限，音程匹配也是可能进行的，尽管明显更差。匹配显示出显著更大的系统误差和更高的变异性，并且与低F0相比，受试者完成高F0匹配所需的试验更多。来自一名具有绝对音高的受试者的额外绝对音高判断，对于包含1 - 5或6 - 10谐波且F0范围广泛的复合音，当最低频率分量低于约7 kHz时判断是完美的，但当最低频率分量为8 kHz或更高时，至少50%的反应是错误的。我们从锁相信息和对高频刺激的熟悉程度对音高的可能影响方面讨论了这些结果。
