An experimental comparison on KEMAR and BHead210 dummy heads for HRTF-based Virtual auditory on Chinese subjects

Head related transfer functions (HRTFs) vary with anatomical structures in head, pinna and torso. As we know, Chinese are highly different from their Western counterparts in anatomical characteristics. In this paper, we perform an experimental study on HRTF-based virtual auditory, in which the HRTF data are collected from two dummy heads: KEMAR and BHead210. KEMAR resembles the head of a worldwide average human and BHead210 replicates the head of an average Chinese. Our preliminary results show significant differences in sound localization performance between the two dummy heads. The localization performance, especially on the frontal plane, of BHead210-collected HRTF is better than KEMAR for Chinese subjects. We believe BHead210 is more suitable for Chinese in HRTF-based virtual auditory applications.
