Abstract

The present disclosure relates to a method of representing the fine structure in a cochlear implant system (CIS) using simultaneous and non-simultaneous current navigation. In a conventional CIS current navigation strategy, envelope is extracted in each channel, and the remaining information (known as the fine structure) is not used or thrown away. Given the number of channels present in a CIS current processor, information in the fine structure is important for understanding speech in modulated noise, and is essential for representing musical melodies.
