Common-Acoustical-Poles/Zeros Modeling of HRTF Using Logarithmic Error Criterion

摘要

摘要: 共声学极点/零点(CAPZ)逼近是头相关传递函数(HRTF)建模的一种高效方法，与极零点模型相比，它可以用更少的参数表示HRTF。传统的CAPZ模型参数估计方法是基于最小均方误差准则，而人的听觉感知系统更适合于对数误差准则，为此，该文提出一种基于对数幅度误差最小化的CAPZ模型参数估计方法。该方法首先使用Haneda方法估计出声学共极点，然后在对数幅度误差准则下，使用迭代加权最小二乘算法估计零点，从而得到完整的CAPZ模型。仿真实验结果验证了其有效性。

Abstract: Common-Acoustical-Poles/Zeros (CAPZ) approximation is an efficient way to model Head-Related Transfer Functions (HRTF), which requires fewer parameters than pole/zero model. Conventional methods estimate CAPZ model parameters based on least square error criterion, while the attributes of human auditory perception are more consistent with the logarithmic error criterion. This paper therefore presents a new method to estimate CAPZ model parameters by minimizing log-magnitude error. Common acoustical poles are estimated with Haneda method firstly. Then, under logarithmic error criterion, the zeros of CAPZ model are estimated with iterative weighted least-square algorithm. Simulation results are given to validate the effectiveness of the proposed method.
