This paper describes the importance of the sense of hearing for immersive telepresence systems, and a fundamental approach to designing and implementing a binaural sensor system. This approach relies on knowledge of how the human auditory localisation mechanisms work to locate sounds in space, in order that a synthetic system can be derived. The most important of these mechanisms are explained. The Strathclyde auditory system is then described including ideas drawn from the literature to define a binaural approach. This novel system consists of a set of artificial pinnae and microphones mounted on a binocular stereo sensor platform capable of pan, tilt and roll which is slaved to a head tracking system. A set of preliminary experiments is described which test the performance of the system in practice, as a basis for further development.
