The measurement of head-related transfer functions (HRTF) is often a time consuming or expensive (or both!) process. This study aims to develop a HRTF measurement technique that uses significantly fewer speaker locations than seen traditionally.
Previous work has shown that binaural reproductions are still effective with as low as fourth-order spherical harmonic truncation imposed on the measured HRTF. This indicates that the spatial resolution used in most HRTF measurement procedures may over-fulfill requirements for good perceptual reproduction. As our lab is concerned with the perceptual rather than the physical, we will validate our measurements with perceptual tests. We hope to see little difference between these ratings and ratings obtained with more robust methods.
If successful, this could lead to easier measurement of HRTFs, expanding the research field and reducing costs and time constraints significantly.
