Estimation of Individualized Head-Related Transfer Function by Principal Component Analysis
Kentaro Matsui, Akio Ando (NHK) EA2008-53
Abstract (in Japanese) (See Japanese page) 
(in English) In binaural reproduction providing spatial sound by means convolving sound sources and head-related transfer functions (HRTFs), it is important to approximate the listener’s own HRTFs with a high degree of accuracy. A method for estimating this individualized HRTFs using principal component analysis (PCA) is introduced, in which the orthogonal bases of a set of HRTFs are computed and partly-measured HRTFs are interpolated from the weighted sum of the bases. The validity of the method was verified in a subjective experiment which evaluated the
needed approximation accuracy of HRTFs.
