3D sound image localization by interaural differences and the median plane HRTF

Abstract

Presented at the 8th International Conference on Auditory Display (ICAD), Kyoto, Japan, July 2-5, 2002.A new 3-D localization method by simulating interaural differences and the HRTF in a sagittal plane is proposed. This method is based on the supposition that the spectral cues would be common in any sagittal plane. Localization tests were performed to examine the method. The results infer that a sound image of any directions can be localized using the HRTF in the median plane and interaural differences. Furthermore, localization tests in which ITD or ILD is simulated separately indicate that ITD is dominant on the perception of the lateral angle
