Human spatial perception of sound is a complex phenomenon. The Head-Related Transfer Function (HRTF) is a vital component to spatial sound perception. In order improve the understanding of the correlation between the HRTF and specific geometry of the head and pinna, a Boundary Element Method (BEM) has been used to calculate a portion of the HRTF of an individual based on precise geometrical data. Advantages of this approach include the ability to alter the geometry of the individual through the model in ways which are not possible with real subjects. Several models are used in the study, including a head with no pinna and several sized spheres. Calculations are performed for various source locations around the head. Results are presented for rigid model cases. Effects of variations on impedance and comparisons to measured data will be presented in the subsequent paper.
人类对声音的空间感知是一种复杂的现象。头部相关传递函数(HRTF)是空间声音感知的重要组成部分。为了更好地理解HRTF与头部和耳廓特定几何形状之间的相关性,已使用边界元法(BEM)根据精确的几何数据计算个体的部分HRTF。这种方法的优点包括能够通过模型以实际对象无法实现的方式改变个体的几何形状。该研究中使用了几种模型,包括没有耳廓的头部和几个不同尺寸的球体。针对头部周围的各种声源位置进行了计算。给出了刚性模型情况的结果。后续论文将呈现阻抗变化的影响以及与测量数据的比较。
