Dynamic Current Steering

A method, comprising:

• receiving one or more sound signals at an auditory prosthesis system;
• processing the one or more sound signals to determine a first stimulation pulse representative of the one or more sound signals;
• and
• delivering the first stimulation pulse as first and second current signals, substantially simultaneously applied at first and second stimulation channels, respectively,
• wherein the first and second current signals are dynamically weighted to substantially continually move a locus of the first stimulation pulse between a location at the first stimulation channel and a location at the stimulation second channel.

One or more non-transitory computer readable storage media comprising instructions that, when executed by a processor of a hearing prosthesis configured to worn by a recipient, cause the processor to:

• receive one or more sound signals at an auditory prosthesis system;
• process the one or more sound signals;
• cause a stimulator arrangement to substantially simultaneously deliver first and second current signals to the recipient via first and second stimulation channels, respectively;
• and
• cause the stimulator arrangement to control instantaneous amplitudes of the first and second current signals based on one or more attributes of the one or more sound signals such that a locus of the first and second current signals continually progresses from the first channel to the second channel.

A tissue-stimulating prosthesis system, comprising:

• one or more sound input elements configured to receive a sound signal;
• a sound processor configured to generate one or more processed signals representative of the sound signal;
• a plurality of stimulation channels each terminating at one or more electrical stimulating contacts implantable in a recipient;
• and
• a stimulator arrangement configured to simultaneously generate, based on at least one of the one or more processed signals, overlapping time varying current fields across two or more of the stimulation channels that collectively result in a time varying change in a locus of the overlapping current fields.
