In this study, we proposed an improved method of localization accuracy based on equal-loudness-level contours and human aural characteristic in which the relation between physical sound volume and sensuous sound volume is nonlinear. We have corrected HRTF (Head-Related Transfer Function) by canceling out the nonlinear characteristic in consideration of equal-loudness-level contours and normalized them per frequency based on the ratio of the total of frequency components in all directions. We conducted experiment in which subjects answered the direction of sound sources which were created stereophonic sounds by binaural simulation from three HRTFs. Localization errors of stereophonic sounds created from corrected HRTFs were decreased by 8 percent average as compared to them of the original HRTFs. |
