A method generating electrical stimuli by an auditory prosthesis () including an array of stimulation devices in response to an incoming acoustic signal, the method including determining stimulation devices to be activated within the array and activation times for those electrodes; and applying a temporal adjustment () to the activation times such that activation of electrodes representing lower-amplitude components of the signal is delayed relative to activation of a proximate device representing a higher-amplitude component of the signal.

Delayed stimulation in auditory prostheses

A method for processing sound signals to generate electrical stimuli for an auditory prosthesis electrode array including a plurality of electrodes, the method including: deriving () one or more filtered representations (FIGS.and) of an incoming audio signal; and, generating () a series of spikes from each filtered signal representation to directly control electrode stimulation. Each spike has a temporal position based upon an instant at which the filtered signal representation crosses a predetermined threshold (&#xff;;).

Generation of electrical stimuli for application to a cochlea

An improved sound processor for a cochlear implant having electrodes for stimulating the auditory nerve, including means for receiving sounds, means for processing the sounds and converting them to electrical stimulation signals for application to the electrodes of the cochlear implant for stimulation of the auditory nerve, said sound processing means including means for generating electrical signals to be applied to the basal electrodes having different predetermined rates of stimulation and the implant having basal electrodes and apical electrodes and the means for generating electrical signals to be applied to the apical electrodes have a different rate of stimulation, the electrical signals to be applied to the basal electrodes having a higher rate of stimulation than the electrical signals to be applied to the apical electrodes.
