![]() ![]() The group mean speech reception threshold in noise (SRT 50) with Nucleus ® 6 SCAN was significantly better (1.2 dB SNR) than with the Nucleus ® 5 ‘Noise’ Program. In addition, recipients had to complete questionnaires and diaries on the use of their current as well as new sound processors and remotes. The remote controls were randomly given during the two B intervals. The Nucleus ® 6 sound processor (condition B) was evaluated in a within-subject ABBA design, with repeated speech in noise (S 0N 0, LIST sentence test), and speech in quiet testing (S 0, NVA words). Secondary objectives included comparisons of speech recognition in quiet, subjective performance feedback via questionnaires and diaries, and recipient preference for device and program type.Ī prospective controlled trial was conducted with 30 adult Nucleus CI recipients using the Nucleus ® 5 sound processor (condition A). 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. 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. ![]() 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. Cochlear'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.
