中文摘要:
      针对基于中国人平均头部尺寸的BHead210标准头模,通过结构光扫描获取三维数据并利用边界元方法计算其头相关传递函数。将刚球模型的计算结果与解析结果进行对比,验证了计算方法的正确性,并将BHead210的计算结果与测量结果对比以观察误差。给出了由边界元计算数据导出的BHead210双耳时间差、双耳声级差曲线与不同声源距离某方位的头相关传递函数幅度谱。最后对比和分析了BHead210头模数据与CIPIC公布的KEMAR头模数据的差异。
英文摘要:
      A numerical method for calculating the head-related transfer function (HRTF) of the Chinese dummy head BHead210 is studied. With the Chinese dummy head BHead210, a structured light scanner is used to obtain its three dimensional data and then the boundary element method is used to calculate its HRTF. The calculation results with a rigid simple sphere model verify its correctness. The comparison results of the numerical calculation and those obtained by acoustic measurement are given. The Interaural Time Difference and Interaural Level Difference curves, different source-distance of HRTF amplitude spectrum are given too. The HRTF of the BHead21 is also compared to those of KEMAR reported by CIPIC.
