本文提出了一种虚拟声源定位误差的研究与个性化的头部相关的传递函数（HRTF）的设计，为盲人的电子旅行援助。所提出的用于辅助视觉残疾人独立移动的设备需要呈现空间声音，这导致需要构建用于有效的个体HRTF测量的系统。对15名视力正常和失明的人进行了测量。仅限于前半球的验证试验表明，可以执行虚拟声源的定位，其准确度达到方位角平均误差6.36度和仰角平均误差9.47度。
The article presents a study of virtual sound source localization errors with the use of personalized head related transfer functions (HRTFs) in light of design of an electronic travel aid for the blind. The proposed device for aiding visually disabled individuals in independent mobility requires presentation of spatial sounds, which lead to the need to construct a system for efficient individual HRTF measurement. Measurements were performed for 15 sighted and blind individuals. Verification trials limited to the frontal hemisphere have shown that the localization of virtual sound sources can be performed with accuracy reaching average errors of 6.36deg in azimuth and 9.47deg in elevation.
