| Outline of Final Research Achievements |
We proposed a method of simultaneous estimation for head-related transfer functions (HRTFs) using a multi-input single-output (MISO) system identification method. A set of multi-directional HRTFs can be regarded as an MISO system, and identified as an MISO finite impulse response model by applied the least squares method. The effectiveness of the proposed methods was verified through the simultaneous estimation experiments of 57 direction HRTF sets of the dummy head and sound localization experiments of 16 subjects. Through the experiments it is verified that the HRTFs estimated simultaneously were nearly equivalent to HRTFs measured one direction by one direction.
