AB  - This paper describes the continuation of research concerning sound source obstruction in virtual scenes. An algorithm for the determination of sound source obstruction was implemented in the described 3D MPEG-4 Environment. With the help of the MPEG-4 Advanced AudioBIFS node AcousticMaterial acoustic properties are assigned to potential obstructors in a virtual scene. Various implementations of acoustic obstruction are explained. Furthermore, a bimodal subjective assessment was performed in order to identify the best implementation of obstruction. The results of the assessment are presented in-depth. Additionally we demonstrate a concept for a second intended bimodal assessment for the comparison of gain and frequency filtering and give an outlook for further research and development in the area of immersive acoustics.
