M5-ESR: A computational model to improve binaural CI speech strategies

Different speech processing strategies have been proposed to optimize binaural hearing with bilateral CIs and bimodal systems (CI and contralateral HA). These strategies aim to improve coding of binaural cues (interaural time and level differences, ITD and ILD) and are generally designed on theoretical bases and psychophysically evaluated. It would be useful to have a functional “test bench” model to predict to what extent the binaural cues are presented to the auditory system. In this project, we aim to develop a biologically inspired model that yields the available interaural cues based on existing models of the auditory periphery. The firing patterns for the two ears (either electric-electric or electric-acoustic) will be the input of a binaural model.
