Acoustic sources for the sound systems, i.e., loudspeakers have unique and individual characteristics such as amplitude frequency response, phase frequency response, transient response, and directivity. Consideration of these characteristics is as important a part of sound system auralization process as the calculation of precise room responses, such as diffusions and diffractions, in architectural acoustic oriented auralization systems. However, no statistical studies have been made on this subject so far. In this study, the importance and advantage of considering sound source characteristics as a transient response are revealed and a practical impulse response calculation algorithm that is accurate enough and practical for auralization of sound system designs is described.
