Efficient simulation of sound-source occlusion is needed, e.g., in auditory virtual environments and remains an unsolved problem. In order to overcome this problem, the changes in psychoacoustical parameters accompanying the perception of sound-source occlusion have to be identified and understood. In this paper the impact of occlusion on the localization of auditory events is investigated with the aid of listening tests. Rectangular wood plates of different dimensions are used as occluders. A noticeable shift in the location of the auditory events is observed. The results can be explained on the grounds of the precedence effect.
