摘要

提出了一种采用三高架扬声器投影的增强型虚拟声成像系统。在鲁棒性分析的基础上，提出了一种有效的听觉图像校正方案，以提高系统性能。这是通过特别设计的逆滤波器和HRTF滤波来实现的。声音成像算法在TMS320C6201 EVMDSP板上实现，并进行了主观测试来验证虚拟声音效果。

Development of virtual sound imaging system using triple elevated speakers

An enhanced virtual sound imaging system using triple elevated-speaker projection is proposed. Based on the robustness analysis, an efficient auditory image correction scheme is developed to improve system performance. This is achieved by specially designed inverse filter together with HRTF filtering. The sound imaging algorithm is implemented on a TMS320C6201 EVMDSP board and subjective testing is also carried out to demonstrate the virtual sound effects.
