AbstractIn a method for constructing an acoustic transfer function table for virtual sound localization, acoustic transfer functions are measured at both ears for a large number of subjects for each sound source position and subjected to principal components analysis, and that one of the transfer functions which corresponds to a weighting vector closest to the centroid of weighting vectors obtained for each sound source position and each ear are determined as a representative.
