The purpose of this paper is to clarify the effects of visual information on corresponding auditory information when they are presented simultaneously in a wide frontal area (180 degrees) on a horizontal plain. Sound localization experiments were carried out both with and without visual stimuli associated with sound stimuli. In the experiments, four different visual images of a human speaker and the four corresponding speech sounds were used as the visual and sound stimuli, respectively. The visual stimuli were projected on a half-cylindrical shaped screen in five directions (-60, -30, 0, 30, 60 degrees), and the corresponding sound stimuli were reproduced in 13 directions (-90, …, -15, 0, 15, …, 90 degrees) via loudspeakers placed in each direction or transaural reproduction using a pair of loudspeakers (±30 degrees). The degree of sound localization accuracy was evaluated according to a five-grade system in cases where visual stimuli were absent. The results obtained showed that a sound image far away from its corresponding visual image (maximum 150 degrees) was affected by the visual image, and that a sound image having a relatively low degree of localization accuracy tended to be strongly affected by the visual image. These results show that, in addition to the relative position of visual and sound stimuli, the degree of sound localization accuracy is one of the important elements in auditory-visual interaction on a wide frontal area.
