Abstract
A computer controlled, three-dimensional, iterative and reiterative, closed-loop system for automatically positioning the head of a manikin situated on a motorized stand relative to a stationary sound source in order to perform accurate near-field Head-Related Transfer Function (HRTF) measurements. The positioning is based on acoustic signals measured from microphones located at each ear of the manikin and is accomplished with three-axis precision for accurate near-field HRTF measuring.
