Abstract: This investigation determines the audibility of edge-diffraction when used in auralization of a stage house. Computed impulse responses with varying orders of diffraction are auralized and compared via listening tests. These impulse responses are also compared with measured, auralized impulse responses from a scale model. Results indicate that, for the positions studied, first-order diffraction is significantly more audible than second-order diffraction. Thus, higher-order edge diffraction calculations can possibly be neglected in auralization programs
