Abstract: This paper aims to test the hypothesis that audiovisual perceptual feedback based training can improve the sound localization accuracy and the navigational skills in a virtual auditory display where 3D sounds are created using non-individualized HRTFs. In our experiment, we tested the spatial auditory localization performance of nine sighted subjects prior and consequently a series of training procedures based on audio-visual feedback. The results concluded that this cross-modal facilitation enhances spatial hearing, reduces the incidence of localization and front-back confusion errors and helps the users to navigate more accurately in the virtual auditory environments by improving their ability to detect 3D sound sources synthesized with non-individualized HRTFs.
