A High Resolution and Full-Spherical Head-Related Transfer Function Database for Different Head-Above-Torso Orientations

基于头、躯干不同朝向的高分辨率全球面头相关传输函数的数据库

 

Head-related transfer functions (HRTFs) capture the free-field sound transmission from a sound source to the listeners ears, incorporating all the cues for sound localization, such as interaural time and level differences as well as the spectral cues that originate from scattering, diffraction, and reflection on the human pinnae, head, and body. In this study, HRTFs were acoustically measured and numerically simulated for the FABIAN head-and-torso simulator on a full-spherical and high-resolution sampling grid. HRTFs were acquired for 11 horizontal head-above-torso orientations, covering the typical range of motion of +/-50°. This made it possible to account for head movements in dynamic binaural auralizations. Because of a lack of an external reference for the HRTFs, measured and simulated data sets were cross-validated by applying auditory models for localization performance and spectral coloration. The results indicate a high degree of similarity between the two data sets regarding all tested aspects, thus suggesting that they are free of systematic errors.

基于FABIAN头和躯干模型的头相关传递函数(HRTFs)在全球面高分辨率采样网格上进行了声学测量和数值仿真。而且,我们基于躯干、头部的11个水平朝向测量获得HRTFs,覆盖了±50度的运动范围,使得它可以说明在正常的身体姿态下听者头部运动时产生的动态双耳听觉。由于缺少HRTFs的外部参考,实测的数据集合和仿真的数据集合只能通过多个听觉模型的定位性能和音染以及相关性分析来交叉验证。验证结果表明两个数据集合在全部测试参数上都高度相似,这说明它们没有系统误差。
