It is possible to include static directivity patterns into auralizations to better represent the way in which real sources radiate sound and subsequently excite the room. Sources such as the voice have directivity patterns which vary with frequency and also due to dynamic movements of the performer. This study presents an investigation of the inclusion of dynamic voice directivity into room acoustic auralizations based on geometrical acoustics (GA) software. Previous studies have performed this using multi-channel anechoic recordings. In contrast, this study employs single channel anechoic stimuli. Focus is on the incorporation of dynamic orientation presenting the means by which it is included into the GA software as well as the results of a subjective listening test. Results indicate that dynamic voice directivity orientation auralizations are perceived as more plausible, more enveloping, and exhibiting greater apparent source width than auralizations with a static voice directivity and omnidirectional sources.
