The present study examined how the particularity of 3D models affects the results of acoustic simulation, which is essential in today’s architectural acoustical design. For this study, four 3D models with different levels of particularity were prepared fo ra real theater, and acoustic simulation was performed. Then, the results of the simulation were compared with actual acoustic measurements. In addition, we prepared sources recorded in the field and auralized listening materials according to the particularity of the 3D models, and compared them through subjective listening tests. The results of this study are summarized as follows. (1) In the results of comparison of objective(physical) acoustic evaluation indexes(SPL, RT) show, when the 3D model was more particular the results of simulation were closer to the results of room acoustic experiment. (2) In the results of a subjective listening test with western music and lectures, most of acoustics majors replied that the auralized listening material of the 3D model that had the smallest physical error from the results of experiment with actual sounds was closest to real sounds. Ordinary people, however, chose the auralized listening material of the 3D model irrelevant to physical errors. |
