中文摘要
头部相关传递函数(HRTF)表示从声源到收听者的每个耳膜的声音传播的特性。与 HRTF 卷积的声音使听者定位虚拟声音。在这项研究中,通过在 GPU(图形处理单元)上并行处理卷积,开发了能够控制多达 42 个虚拟声音的听觉显示系统。该系统可以实现到笔记本电脑中。因此,该系统还具有较高的可移植性。
英文摘要
A head-related transfer function(HRTF) represents characteristics of sound propagation from a sound source to each eardrum of a listener. The sound convolved with HRTF makes a listener localize a virtual sound. In this study, an auditory display system that is able to control up to 42 virtual sounds is developed by processing the convolution in parallel on GPU(graphics processing unit). This system can be implemented into a notebook computer. Therefore, the system also has a high portability.
