dc.description.abstractIn the context of room-acoustic simulations, diffraction around obstacles with edges still poses a significant challenge. This work focuses on solutions of diffraction problems on finite wedges with the goal of creating efficient and accurate room acoustic simulations. The solutions are based on the physical theory of diffraction. A detailed discussion of integral and asymptotic expressions for the diffracted field, radiated by secondary wedge sources, is offered in order to elaborate problem-solving strategies for grazing incidence scenarios. Due to the fact that the computational load of an asymptotic solution is orders of magnitude less than that of an exact solution using the physical theory of diffraction, any possible means of reducing asymptotic error without significantly increasing computational load is of critical importance in practical room-simulations. This work will discuss implementations based on the physical theory of diffraction. For several canonical configurations, the thesis will also present a discussion of asymptotic error as a function of incident source distance and direction.
