Design and Implementation of HRTF Database Based on BHead210

Xiaohai Tian

Abstract

Head-related transfer functions(HRTFs) describe the transfer process of sounds from a point source to a point of the listener's ear canal.It includes all the necessary information of sound localization.This paper constructs an HRTF measurement system and builds an HRTF database.This database consists of head-related impulse response(HRIR) data of the BHead210 dummy head which reflects the average Chinese head.The HRIR data are sampled at 481 different spatial positions in total.A comparison study between HRTF data of BHead210 and KEMAR is carried out on the HRTF-based virtual auditory.
