Research Abstract

In order to illuminate auditory space, sound lateralization tests were performed to compare the magnet coil bone-conduction headphone with the giant magnetostrictive bone-conduction headphone using 18 healthy participants. Although, no significant difference between these bone-conduction headphones was obtained for the interaural time difference and interaural intensity difference, a significant difference was obtained for the time-intensity trade. This revealed that the difference between the headphone is apparent in the integration of the heterogeneous sensations of the time and intensity difference at the cognitive level, but no difference is apparent between the homogeneous sensations of the discrimination of interaural time difference or interoaural intensity difference at the sensory level. It was concluded that the difference of the giant magnetostrictive headphone. However, sound localization test using speakers' method in the aneic room revealed that auditory space of bone conduction is smaller than that of airconductive.
