Generation of the individualized HRTFs in the upper hemisphere by optimizing the notch frequency of the HRTF of the zenith direction
Fuka Nakamura, Kazuhiro Iida (CIT) EA2022-35
Abstract (in Japanese) (See Japanese page) 
(in English) In order to realize three-dimensional sound image localization and acoustic VR, methods for generating head-related transfer functions (HRTFs) for individual listeners have been actively studied. In the present paper, we proposed a method that estimates the notch frequencies for the front and rear directions from the notch frequencies individualized in the zenith direction using the PNP (Parametric Notch-Peak) HRTF model and generates individualized HRTFs for an arbitrary direction in the upper hemisphere. Then, we have developed a toolkit that generates individualized HRTFs based on the proposed method. Results of the sound image localization tests showed that the individualized HRTFs provide accurate sound image localization in the horizontal plane and the transverse plane. In the median plane, the individualized HRTFs provide accurate sound image localization for the front, zenith, and rear directions, however, there is still room for improvement in localization accuracy for the vertical angles of 30°, 60°, and 120°.
