An Experiment to Evaluate the Performance of a Parametric Model for the Individualization of the HRTF in the Median Plane

Individualized HRTFs for headphone reproduction provide better immersion and natural localization of sounds than non-individualized, especially for elevated positions. This paper presents an experiment to determine the accuracy of individualized parametric modeled HRTFs. The modeling of the HRTFs was done with an algorithm that detects the main peaks and notches of the HRTF and models them with a chain of second order IIR peak filters. A subjective test was carried on to compare the perception and localization of the modeled versus measured HRTFs in the median plane. The analyzed data shows that simplified modeled versions of HRTFs with a few peaks simulated can obtain similar results than measured HRTF for elevation angles in the median plane.
