这项研究考察了受试者识别两个同步双音复合体中两个缺失基音的音高的能力，这两个双音复合体的分音以不同的方式分布在受试者的耳朵之间。数据显示识别性能受到不同程度的影响。外围听觉系统中有限的频率分辨率可能会降低性能，但前提是四个刺激分音中没有一个在听觉上得到解析。识别性能仅微弱地依赖于在耳朵之间分配分音的方式。在某些情况下，人们发现，可能在非常核心的层面（例如注意力），两个同时音高的识别过程会相互干扰。当一个双音复合体的谐波阶次较高时，一些受试者比该复合体的谐波阶次较低时更有可能识别出另一个复合体的音高。最后，一些受试者倾向于分析地听到复杂的音调，即感知单个分音的音高，而不是耳朵之间某些分音分布的缺失基音。
This study examines subjects'' ability to recognize the pitches of two missing fundamentals in two simultaneous two-tone complexes whose partials are distributed in various ways between subjects'' ears. The data ahow that identification performance is affected on different levels. Limited frequency resolution in the peripheral auditory system can degrade performance, but only if none of the four stimulus partials is aurally resolved. Identification performance is only weakly dependent on the manner of distributing partials between the ears. In some cases it was found that, probably at a very central level (e.g., attention), the identification processes of both simultaneous pitches interfere with one another. Some subjects are more likely to identify the pitch of one two-tone complex when the harmonic order of the other complex is higher than when this harmonic order is lower. Finally, some subjects tend to hear the complex tones analytically, i.e., perceive pitches of single partials instead of the missing fundamentals for some distribution of partials between the ears.
