原则上，戈尔茨坦的最佳处理器理论可以解释涉及同时二分复音的音调感知现象。频率编码噪声函数是该模型的唯一自由参数，它是通过向不同耳朵呈现的两个同时双音复合体的音高识别数据来估计的。发现该“西格玛”函数的形状与从单个音高的识别性能数据导出的函数的形状相似。同时音高识别实验中的西格玛因受试者而异，其量较大。通过使用不同的数据分析方法，发现对于大多数受试者来说，两种音调的音调估计过程是独立的。这使得戈德斯坦的最优处理器理论得以简单扩展。
The optimum processor theory of Goldstein can, in principle, account for pitch perception phenomena involving simultaneous dichotic complex tones. The frequency-coding noise function, which is the only free parameter of the model, was estimated with pitch identification data of two simultaneous two-tone complexes presented to different ears. This "sigma" function was found to have a shape similar to that of the function derived from data on identification performance for single pitches. The sigmas in the simultaneous pitch identification experiment are larger by an amount that differs from subject to subject. By using different methods of data analysis it was found that the pitch estimation processes for the two tones are independent for most subjects. This allows a simple extension of Goldstein''s optimum processor theory.
