Patent number: 9084892Abstract: The sound processor and method uses a model of basilar membrane motion to select stimuli, based upon the predicted motion which the acoustic signal presented would produce in an acoustically excited normally hearing cochlea. The filter; used, in contrast to single channel per electrode approaches, cover multiple channels and overlap with each other. Consequently the stimuli presented produce a neural excitation pattern which approximates the spatio-temporal travelling wave observed on the basilar membrane in an acoustically excited normally hearing cochlea. Preferably, the predicted electrode stimuli are based upon the instantaneous predicted amplitude of the electrode location.Type: GrantFiled: June 15, 2006Date of Patent: July 21, 2015Assignee: Cochlear LimitedInventors: Peter J. Blamey, Brett A. Swanson, Hugh McDermott, James F. Patrick, Graeme M. Clark
