摘要

A directional band model of median-plane localization has been developed. Perception of sound direction for a narrow band noise in the median plane depends mainly on the center frequency and bandwidth. In median-plane localization, a frequency band limited stimulus gives perception associated with a given direction. Earlier studies were commonly implemented for the median plane and binaural hearing. No directional band model of monaural hearing, however, has been examined. Moreover, none for another plane has been examined sufficiently. For this research, we make an extension of a directional band model: we examine features in a different plane (e.g., the horizontal plane) and monaural hearing. For this study, stimuli were applied from loudspeakers on the upper hemisphere surface. Results of experiments conducted for direction recognition demonstrate that some frequency bands in monaural hearing correspond to specific directions. Additionally, we clarified features of the directional band model for binaural hearing aside from the median plane, which suggests the possibility of a directional band model of 3-D space localization.
