The effect of early impulse response length and visual environment on externalization of binaural virtual sources
Sinker, J; Shirley, BG
Abstract
When designing an audio-augmented-reality (AAR) system capable of rendering acoustic “overlays” to real environments, it is advantageous to create externalized virtual sources with minimal computational complexity. This paper describes experiments designed to explore the relationships between early impulse response (EIR) length, visual environment and perceived externalization, and to identify if reduced IR data can effectively render a virtual source in matched and unmatched environments. In both environments a broadly linear trend is exhibited between EIR length and perceived externalization, and statistical analysis suggests a threshold at approximately 30-40 ms above which the extension of the EIR yields no significant increase in externalization.
