Aachener Beiträge zur Akustik, Bd. 35
This thesis presents a comprehensive database intended for the validation of room acoustic simulation software. It includes eleven acoustic scenes, covering both simple environments and complex rooms. In addition to a detailed description and the definition of input data, acoustic measurements were carried out for all scenes.
Furthermore, two studies are presented in which simulated and measured data for selected scenes of the developed database are compared. The first study, a round robin experiment with up to six participants, reveals various shortcomings of simulation models based on geometrical acoustics. The second study demonstrates how deviations of simulated results decrease when measured data is known beforehand and input data of the simulation is adjusted manually or systematically. The database along with the findings of the two presented studies provide a basis for the future revision of room acoustic simulation software.
