Conversion of adult Nucleus® 5 cochlear implant users to the Nucleus® 6 system

AbstractObjectivesCochlear's new sound processor system (Nucleus® 6) features a new noise reduction algorithm called SNR-NR (signal-to-noise ratio), and an environmental classifier called SCAN, which activates the appropriate sound coding algorithms for a given listening environment. In addition, the sound processors (CP910 and CP920) have a data logging feature with data visually summarized using clinical programing software and come with two remote controls, CR210 and CR230. The objective of this clinical study was to conduct a field acceptance study comparing the user experience with the Nucleus® 6 to the Nucleus® 5 system and to evaluate the benefits of Nucleus® 6 in an adult population currently equipped with the previous generation Nucleus® 5 sound processor. Our primary objective was to compare speech recognition in speech-weighted noise using Nucleus® 6 with SCAN (activating SNR-NR) with the default Nucleus® 5 ‘Noise’ Program. Secondary objectives included comparisons of speech recognition in quie...
