传统基于声音物理性质的声场重建方法构建的球体模型听音点位置固定于头部中心,与实际人接收声音的位置位于左、右耳处的情况不相符,导致采用此方法重建的声场与实际声场存在一定偏差。针对此问题,提出基于声音物理性质的双耳声场重建方法,选取左、右耳为听音点,并计算在水平方向头部转动的最佳听音角度,保证双耳处获得虚拟声像最佳的空间感知。实验表明,与传统基于声音物理性质的声场重建方法相比,本文方法在双耳范围内整体的声场重建精度提高10. 66%,并且能在听音测试中给予听音者对虚拟声源更佳的空间感知。

The location of the listening point of the sphere model built by the traditional sound field reconstruction method based on the physical properties of sound is fixed at the center of the head,which is inconsistent with the fact that the position of the actual person receiving the sound is located at the left and right ears.Therefore,there is a certain deviation between the reconstructed sound field and the actual one.To solve this problem,a reconstruction method of binaural sound field based on sound physical properties is proposed.The left and right ears are selected as listening points,and t...
