Abstract

Our previous work showed that the presence of pinnae produces a spectral notch in HRTFs for sound sources behind a listener (labeled N0). This spectral notch appears at frequencies lower than N1 and N2, as reported in previous works, as necessary cues for sound image localization. In this study, we examined the spatial distribution of N0 and subsequently conducted psychoacoustical experiments to clarify how N0 affects sound localization. Experimental results showed that N0 has little effect on front-back judgment, but that it has significant effects on sound localization in elevation.
