Influence of processing strategies on cochlear implant performance.

The development of new processing strategies has allowed for the improvement of auditory skills in cochlear implant recipients. This study examines the effects of a change in processing strategy on the individual recipients of the Nucleus cochlear prosthesis. Twenty-five subjects who had used the F0F1F2 processing strategy (WSP III) for 2 years were switched to the MPeak strategy (MSP) and retested immediately and after 3 months. Results revealed an improvement in speech recognition ability with the MPeak strategy in those subjects who were able to perceive speech with the F0F1F2 processing strategy.
