The ability of humans to perceive the spatial location of a sound is of great practical and research importance.
The recent advances in computational power and acoustic measurement techniques have make the study of head related transfer function (HRTF) a rapidly growing area with potential uses in virtual reality audio applications.
This research focuses on:
- parsimonious representation of HRTFs
- efficient and less cumbersome HRTF measurement techniques
- applying binaural techniques in communication systems, for situations where the listener must hear more than one communication channel at a time.
Implementations of this kind of system can be used for pilots, air control towers and spatial audio teleconferencing.
