SUMMARY:Fan: Evaluation of the Level of Detail in Classroom Auralization
DESCRIPTION:This paper describes the results of a subjective evaluation of classroom auralizations with different levels of detail(LOD) by a listening test. Computer Modeling of the classroom with different LOD and the auralizations are realized by using RAVEN\, after which the listening test procedure and the analyzed results are presented. The task of listening test is to compare auralizations with a sound sample in the real classroom. The experiment shows that a model with specific level of detail\, a saturation value of minimum difference can be achieved. However\, this has some limitations and some modelling issues that need to be discussed. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 939 3034 2718\nPasswort: 360178

SUMMARY:Pan: Impact of Geometry Reduction on Room Acoustic Simulation
DESCRIPTION:Conventional acoustic simulations are based on CAD models. The creation of the 3D model requires modeling expertise and time. Additionally\, the variety of model strategies makes this process difficult to reproduce. In contrast\, Photogrammetry techniques can economically achieve valid representations of rooms. However\, the models created using Photogrammetry are aimed at visualization purposes. The models are usually too detailed for an acoustic simulation program. Therefore\, the acoustically irrelevant details in the 3D models are desired to be removed for an acoustic simulation. \nFor this reason\, we studied a 3D model created using the Photogrammetry technique. We derived several simplified models with different reduction rates using the geometry reduction algorithm from the Photogrammetry 3D model. Furthermore\, we performed the manual material assignment and the semi-automatic material assignment on the models. Acoustic simulations are used to evaluate the models with different reduction rates and different material assignment approaches. The potentials and limitations of using the geometry reduction method and different material assignment approaches to create an acoustic model from a 3D Photogrammetry model are discussed. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 939 3034 2718\nPasswort: 360178
