一些理论认为，和谐的感知是基于神经周期性检测的，而神经周期性检测依赖于听觉神经纤维对刺激波形特征的精确锁相。在当前的研究中，要求15名听众对形成各种谐波间隔并在高频区域（所有分量>5.8 kHz）中进行带通滤波的复杂音调二对（2个音符和弦）的愉悦度进行评级，其中认为快速刺激精细结构的锁相严重退化或不存在。这两个音符传到了相反的耳朵里。协和音程（小三度和完全五度）比不协和音程（小三度和三全音）获得更高的评分。结果不能解释相位锁定到较慢的波形包络，因为当刺激是谐波时，对辅音间隔的偏好更高，与通过将其分量频率移动恒定偏移量以保持其包络周期性而使其不谐波的条件相比。总的来说，结果表明，如果相位锁定确实是不存在的频率大于类似5 kHz，神经周期性检测是没有必要的和谐的感知。(C)2019年作者。所有文章内容，除非另有说明，是根据知识共享署名（CC BY）许可证（http：//creativecommons.org/licenses/by/4.0/）。
Some theories posit that the perception of consonance is based on neural periodicity detection, which is dependent on accurate phase locking of auditory nerve fibers to features of the stimulus waveform. In the current study, 15 listeners were asked to rate the pleasantness of complex tone dyads (2 note chords) forming various harmonic intervals and bandpass filtered in a high-frequency region (all components >5.8 kHz), where phase locking to the rapid stimulus fine structure is thought to be severely degraded or absent. The two notes were presented to opposite ears. Consonant intervals (minor third and perfect fifth) received higher ratings than dissonant intervals (minor second and tritone). The results could not be explained in terms of phase locking to the slower waveform envelope because the preference for consonant intervals was higher when the stimuli were harmonic, compared to a condition in which they were made inharmonic by shifting their component frequencies by a constant offset, so as to preserve their envelope periodicity. Overall the results indicate that, if phase locking is indeed absent at frequencies greater than similar to 5 kHz, neural periodicity detection is not necessary for the perception of consonance.
