Parameter selection and programming recommendations for the ACE and CIS speech-processing strategies in the Nucleus 24 cochlear implant system.

Abstract

This study evaluated a range of programming parameters available for the ACE and CIS speech-processing strategies in the Nucleus 24 cochlear implant system. Specifically, the effect on speech perception of adjustments to the number of channels and the stimulation rate in the CIS strategy, and the effect of adjustments to the number of maxima in the ACE strategy were investigated in a group of adult subjects. Based on these findings, and the results of a previous study (Vandali et al., 2000), a number of recommendations for programming were identified that could improve efficiency in the clinical setting where time may be limited. The results suggest that speech perception benefits may be max..
