Psychoacoustic Investigations On Sound-Source Occlusion

摘要

Efficient simulation of sound-source occlusion is needed, for example, in auditory virtual environments, and remains an interesting and at present not widely researched topic. In order to achieve plausible and efficient simulation, the changes in psychoacoustical parameters accompanying the perception of sound-source occlusion have to be identified and understood. 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 grounds of the precedence effect.
