摘　　要：虚拟现实与多媒体技术的快速发展使三维音频的应用增多。传统的三维音频感知测量主要集中在人耳对方位感知性能上,欠缺对距离感知性能的深入研究,现有的三维音频感知特性的研究不足以支撑三维音频在距离感知性能方面的提升。通过三维音频距离感知敏感度的实验,得到距离、角度等因素对距离感知敏感度变化的影响规律,以及不同距离时的距离感知阈值。The rapid development of virtual reality and multimedia technology enables a rise in the market demand for 3 D audio experience.The traditional 3 D audio perception measurement mainly focused on the performance of human ears’ orientation perception,with a lack of in-depth research on distance perception performance.In addition,the existing research on the characteristics of 3 D audio perception proves insufficient to support the improvement of 3 D audio in distance perception performance.Therefore,this paper designs the experiment of three-dimensional audio distance perception sensitivity,and obtains the influence rules of such factors as distance and angle on the change of distance perception sensitivity,as well as the distance perception threshold values at various distances.
