Abstract

Occlusion has been found to compel visual perception of object position and scene analysis [G. A. Kaplan, Percept. Psychophys. 6, 193–198 (1969); W. H. Warren and S. Wang, J. Exp. Psychol. 13, 371–383 (1987)]. Auditory occlusion may also provide salient information about the locations of both sound sources and surfaces in an acoustic scene. In the current experiment, blindfolded participants were asked to listen to sound occluded by an aperture and judge whether unobstructed passage was afforded for various aperture sizes (e.g., W. H. Warren and S. Wang, 1987). Judgments were found to be highly accurate, suggesting the salience of occlusion information for auditory perception. Information from the relative loudness between aperture sizes may have contributed to this ability.
