Effect of the contact condition of the actuator on the sound localization of bone-conducted reproduction

Abstract

To realize three-dimensional sound reproduction using a bone-conducted sound reproduction device, the effect of the contact condition between the actuator of the bone-conducted device and the surface of each part of the face on the sound localization performance of binaural sound signals reproduced by the device via bone conduction was investigated. As a result of a subjective evaluation experiment, it was found that the sound localization performance of bone-conducted binaural sound was increased owing to the contact force and position of the actuator device.
