ABSTRACT:
A system and method for preserving temporal and spatial resolution in complex sounds for poor performing patients having high stimulation thresholds is described. The system and method employs two or more adjacent electrode contacts to deliver concurrent stimulation. This concurrent delivery of stimuli creates a high current field intensity that overlaps between individual current fields generated by the two or more adjacent electrodes and which individual fields are summed to create an overlapping field that has a higher current field intensity than a single current emanating from an individual electrode. The use of this method reduces or eliminates the need to increase either the stimulus current amplitude or to increase the pulse width, both of which may cause loss of system resolution, i.e., loss of fine structure information that is used to resolve complex sounds such as music.
