高频纯音（>6 kHz）本身不产生显著的旋律音高信息，当它们形成具有较低基频（F0）的谐波复音的一部分时，它们提供旋律音高信息。我们探讨了这一现象，在正常听力的听众通过测量F0差阈（F0 DLs）的谐波复合音和纯音频率差阈（FDLs）的谐波复合内的每个音。测试了两个光谱区域。低频和高频带通区域分别包括280或1，400 Hz F0的谐波6-11;因此，对于高频区域，存在的可听频率都在7 kHz以上。频率歧视的非谐波对数间隔音复合体也进行了测试，在控制条件。所有音调都在噪声背景中呈现，以限制失真产物的检测。如在先前的研究中发现的，对于每个组成纯音，低区中的F0 DL通常并不比FDL好。相比之下，高区域复合体的F0 DL大大优于大多数组成（高频）纯音的FDL。数据进行了比较，与最佳的光谱整合的信息模型，以评估周边和更中心的噪声在限制性能的相对影响。研究结果表明，在音高信息的方式是在低，高频率集成的分离，并提供了新的挑战和约束，在寻找潜在的神经机制的音高。
High-frequency pure tones (>6 kHz), which alone do not produce salient melodic pitch information, provide melodic pitch information when they form part of a harmonic complex tone with a lower fundamental frequency (F0). We explored this phenomenon in normal-hearing listeners by measuring F0 difference limens (F0DLs) for harmonic complex tones and pure-tone frequency difference limens (FDLs) for each of the tones within the harmonic complexes. Two spectral regions were tested. The low- and high-frequency band-pass regions comprised harmonics 6–11 of a 280- or 1,400-Hz F0, respectively; thus, for the high-frequency region, audible frequencies present were all above 7 kHz. Frequency discrimination of inharmonic log-spaced tone complexes was also tested in control conditions. All tones were presented in a background of noise to limit the detection of distortion products. As found in previous studies, F0DLs in the low region were typically no better than the FDL for each of the constituent pure tones. In contrast, F0DLs for the high-region complex were considerably better than the FDLs found for most of the constituent (high-frequency) pure tones. The data were compared with models of optimal spectral integration of information, to assess the relative influence of peripheral and more central noise in limiting performance. The results demonstrate a dissociation in the way pitch information is integrated at low and high frequencies and provide new challenges and constraints in the search for the underlying neural mechanisms of pitch.
