Sounds are said to be externalized when we hear them originate from outside the head. This paper investigates if visual stimuli alone can in uence the perceived externalization. An externalization test is performed on six normal hearing test subjects in three di erent environments where the visual stimuli is varied and the sound stimuli held constant using headphone based virtual sound. The virtual sound stimuli are based on the test subjects' own Head-Related-Transfer-Functions (HRTFs). Signi cant di erences (p < 0:001) are observed on the externalization performance when the visual impressions of the test rooms is varied. It is concluded that auditory externalization not only rely on the acoustic stimuli but also on visual impression of the room in which the sound source is located in.
