Impact of Artificial Reverberation on Perceived Sound Localization During a Headphone Listening Task
A commercially available acoustic simulation software with integral normalized Head Related Transfer Function (HRTF) was utilized to create virtual sound spaces, reverberation, and auralization. Four men and four women with self-reported normal hearing were tested individually in a room specifically designed for audiological research. Stimuli were presented via headphones and subjects responded via a custom Graphical User Interface (GUI). Azimuth had a significant effect on all of the dependent variables. Gender differed significantly with respect to distance judgement. Room type significantly affected elevation judgement. In addition, there were interactions between gender and azimuth (azimuth judgement), room and reverberation type (distance judgement), and reverberation type and azimuth (distance judgement).
