A study was performed using headphone-delivered virtual speech stimuli, rendered via HRTF-based acoustic auralization software and hardware as well as blocked-meatus HRTF measurements. The independent variables were chosen to evaluate commonly held assumptions in the literature regarding improved localization: inclusion of head tracking, individualized HRTFs, and early and diffuse reflections. Significant differences were found for azimuth/elevation error, reversal rates, and externalization.:
