1. A neural stimulator device for electrically stimulating a recipient, comprising:
- a stimulus generation device configured to determine a stimulus set of electrical stimuli;
a processor configured to analyze said stimulus set to determine if any of said stimuli are likely to be masked upon delivery of the stimulus set to the recipient, and to delete one or more of said stimuli likely to be masked; and
an electrode array configured to deliver the stimulus set to the recipient.

Abstract
Neural stimulation device with improved power consumption and/or effectiveness. The device is configured to recognize proposed stimuli which will be masked by earlier or simultaneous stimuli. Such masked stimuli are either deleted, or replaced by another stimuli.

16. A neural stimulator device for electrically stimulating a recipient, comprising:
-
a stimulus generation device configured to determine a stimulus set comprising one or more electrical stimuli; a processor configured to analyze said stimulus set to determine if any of said one or more stimuli are likely to be masked upon delivery of the set to the recipient, and to delete at least one of said one or more stimuli in said stimulus set if masking effects are detected; and an electrode array configured to deliver the stimulus set to the recipient. - View Dependent Claims (17, 18, 19, 20, 21, 22)
