Outline of Final Research Achievements

This research has its aims at acquisition of individual Head-Related Transfer Functions (HRTFs) without any limitation due to Time(T), Place(P), and Occasion(O). By using data of the HRTFs acquired in the affiliation of principal investigator and an open dataset of the HRTFs, the principal investigator proposed a new method for estimation of individual HRTFs based on the Principal Components Analysis (PCA). He also indicated that the PCA whose domain is set to frequency amplitude or complex frequency spectrum brings about the most compact representation of the spatial variation of HRTFs. These findings have their effects for mitigating the limitations from the T and the O. As for the limitation from the P and the O, he developed a software for measurement of individual HRTFs. Publication of this achievement is now in progress.
