Towards Mobile 3D HRTF Measurement
AES Convention 148 · Paper 10364 · May 2020
Abstract
Virtual reality (VR)-based measurement systems have recently been developed to quickly measure individual head-related transfer functions (HRTFs) with arbitrary head movements. However, these systems are usually limited to estimate 2D HRTFs with a ?xed distance between the loudspeaker and the subject. In the present study, a mixed reality (MR)-based mobile measurement system for fast estimation of distance-dependent HRTFs (3D HRTFs) is proposed. During the measurement, subjects can not only rotate their heads but also move their bodies towards or away from the loudspeaker. Additionally, the qualities of estimated HRTFs are calculated and displayed to subjects in real-time. Furthermore, the in?uences of the MR head mounted display (HMD) on the far- and near-?eld HRTFs are objectively evaluated.
