| Outline of Final Research Achievements |
A fast HRTF (head-related transfer function) measurement system based on the reciprocal method was developed, in which the measuring signal emanates from a miniature speaker placed at a listener’s ear is simultaneously received by multiple microphones placed around the listener’s head. It took less than 15 seconds to measure HRTFs at multiple locations with the system. Using the fast HRTF measurement system, we measured HRTFs when a listener rotates his head, HRTFs of near-field to far-field, and HRTFs of grid locations on a 2D-plane, and synthesized binaural signals that reproduce approaching/retreating sound image or moving sound image of character trajectories.
