I recently located a copy of an evaluation report that I had collaborated on at Wright-Patterson Air Force Base. We had compared an "off the shelf", system for creating listener specific HRTF functions (if such a thing can be called off the shelf) to a more rigorous approach. The results were dissapointing to say the least -
"The SNAPSHOT MX is a system designed to collect individualized Head- Related Transfer Functions (HRTFS) quickly and efficiently in non-anechoic rooms. This report outlines the SNAPSHOT system and presents the results of a study comparing auditory localization performance with individualized HRTFs measured with the SNAPSHOT to generic HRThs measured with the SNAPSHOT on the Knowles Electronics Manikin for Acoustic Research (KEMAR) and to the genetic SDO transfer functions packaged with the Convolvotron. The results indicate that localization performance is significantly worse with the individualized SNAPSHOT HRTFs than with the genetic SDO HRTFs."
