| Outline of Final Research Achievements |
Humans perceive sound three-dimensionally thanks to auditory cues generated by reflections in the outer ear. In this project we developed advanced techniques in computer simulation of acoustics, to study the influence of ear shape and skin reflection coefficient on the auditory cues. The results reveal how the surface of the ear should be physically manipulated to enhance auditory cues for sound source localization.
