Room Acoustics Simulation Application
Krbila, Martin ; Szőke, Igor (referee) ; Mošner, Ladislav (advisor)
This thesis deals with simulation of room acoustics. The first part of this thesis contains theoretical description of existing aproaches to simulation of acoustics and compares their strenghts and weaknesses. For the purpose of impulse response calculation, several geometrical methods were implemented, such as ray tracing, image method and a combination of those two methods. Application with graphical and text user interface was created, to allow simulation of rooms with arbitrary geometry. The application also allows user to obtain impulse response in a form of a sound file, to visualize the results and the process of sound simulation and to perform auralization. The results of the simulation were compared with measured impulse responses of real rooms. The comparison showed, that the hybrid method is the most accurate of methods implemented in this thesis, and that the best results are achieved by simulation of empty medium-sized or large rooms.
