使用声压和梯度，可以很好地近似包围人类头部的空间区域内的 700Hz 以下声场。通过这种表示，可以找到所得到的耳间时间差 (ITD) 和耳间电平差 (ILD) 的方便表达式。该公式有助于研究自然场和合成场的各种与头部相关的现象。例如，感知图像方向与头部方向和声场描述相关。然后将该结果应用于通用振幅平移系统，并可用于创建相对于头部方向稳定的图像。
Below 700Hz sound fields can be approximated well over a region of space that encloses the human head, using the acoustic pressure and gradient. With this representation convenient expressions are found for the resulting Interaural Time Difference (ITD) and Interaural Level Difference (ILD). This formulation facilitates the investigation of various head-related phenomena of natural and synthesised fields. As an example, perceived image direction is related to head direction and the sound field description. This result is then applied to a general amplitude panning system, and can be used to create images that are stable with respect to head direction.
