T10 - Binaural Auditory ModelsPresenter:
Ville Pulkki, Aalto University - Espoo, Finland
The working principles of brain mechanisms of binaural hearing have been debated during the last decade. In 1990s the common thinking was that human binaural decoding is based on delay lines and coincidence counters, as proposed by the Jeffress model. Later, some neurophysiological findings questioned the existence of such delay lines, and some evidence was found bolstering the count-comparison model proposed by Bekesy. In a count-comparison model, the binaural differences are rate-coded between the left and brain right hemispheres. This tutorial will introduce the basic principles of most common binaural auditory models and review some latest improvements in the models.
