先前的研究表明，窄带声音的耳间互相关系数（IACC）与其感知的听觉源宽度之间的关系取决于其频率。然而，这种依赖性尚未得到足够详细的研究，研究人员无法对其进行正确建模，从而生成感知相关的基于 IACC 的听觉源宽度模型。因此，进行了一系列实验，以受控方式研究这种频率依赖性，并得出适当的模型。在这些实验过程中发现了三个主要因素。首先，确定了 IACC 为 1 的刺激的感知听觉源宽度的频率依赖性的性质，并导出了适当的数学模型。其次，由于耳朵中的锁相故障导致高频感知时间细节的损失，被发现是相关的，并且使用整流和低通滤波器对模型进行了相应的修改。最后，人们发现低频存在进一步的频率依赖性，并导出了对此进行建模的方法。最终模型可以很好地预测实验数据。
Previous research has indicated that the relationship between the interaural cross-correlation coefficient (IACC) of a narrow-band sound and its perceived auditory source width is dependent on its frequency. However, this dependency has not been investigated in sufficient detail for researchers to be able to properly model it in order to produce a perceptually relevant IACC-based model of auditory source width. A series of experiments has therefore been conducted to investigate this frequency dependency in a controlled manner, and to derive an appropriate model. Three main factors were discovered in the course of these experiments. First, the nature of the frequency dependency of the perceived auditory source width of stimuli with an IACC of 1 was determined, and an appropriate mathematical model was derived. Second, the loss of perceived temporal detail at high frequencies, caused by the breakdown of phase locking in the ear, was found to be relevant, and the model was modified accordingly using rectification and a low-pass filter. Finally, it was found that there was a further frequency dependency at low frequencies, and a method for modeling this was derived. The final model was shown to predict the experimental data well.
