Abstract
A method of modeling the human head is provided. The human head model has a width and an aspect ratio. The aspect ratio defines different head shapes independent of the size of the human head model. The method includes the steps of forming a high-frequency head model based on ray-tracing and a plurality of half plane sections, coupling the high-frequency head model with a far-field shadowing filter, coupling the far-field shadowing filter with a near-field compensation filter to compensate for acoustic changes between the far-field and near-field regions and modifying the aspect ratio of the human head model to configure variable geometric models of the human head ranging from a nearly spherical to a very narrow embodiment.
