简单的听觉位置理论提出了这样的问题：听者可能将几种混合谐波归因于其适当的基频：在存在其他声音的情况下识别元音声音需要检测元音的共振峰，而不是将其与其他声音分类。因此，来自基底膜特定部分的神经信息可能以某种方式传达有关基频的信息，该部分对基底膜所响应的谐波进行响应。两只耳朵上的声音融合问题仅仅是一只耳朵上不同频率的融合问题的延伸。结果表明，综合起来，当第一个共振峰呈现给一只耳朵而第二个共振峰呈现给另一只耳朵时，产生的语音会融合，但如果给定不同的共振峰基频，则不会发生这种情况。即使当两个共振峰被给予同一只耳朵时，后一种情况也无法融合。对持续共振峰的进一步实验表明，双耳融合不能用两只耳朵上的某些傅立叶分量的特性来解释。
A simple place theory of hearing raises the problem that several mixed harmonics may be attributed by the listener to their appropriate fundamental frequencies: the recognition of a vowel sound in the presence of other sounds requires that the formants of the vowel be detected as such and not classified with the other sounds. Thus, the neural message from a particular part of the basilar membrane probably conveys in some way information on the fundamental frequency, to a harmonic of which that part of the membrane is responding. The problem of fusion of sounds on the two ears is merely an extension of the problem of fusion of different frequencies in one ear. It is shown that synthetically,produced speech will fuse when the first formant is presented to one ear and the second to the other, but it will not do so if the formants are given different fundamental frequencies. Even when both formants are given to the same ear, the latter condition fails to fuse. A further experiment with sustained formants shows that binaural fusion is not explained by the identity of some of the Fourier components on the two ears.
