Performance Data
The HiRes 90K Advantage implant with the HiFocus Electrode and Naída CI processor support
the HiResolution family of sound processing strategies including HiRes, HiRes with Fidelity 120
(HiRes 120), and ClearVoice.
HiRes™ and HiRes Fidelity 120™ Sound Processing
A clinical study was conducted in 50 adults implanted with a CII/HiRes 90K device who used
a Harmony processor to document the benefits of HiRes 120 and HiRes sound processing.
Performance with HiRes was accessed at the baseline visit and compared with HiRes 120
performance after three months of listening experience. Subsequently, subjects were refit and
retested with HiRes. Results showed equivalent mean CNC word recognition scores for the two
strategies. The mean HINT sentence perception scores in quiet and noise were significantly
higher for HiRes 120 compared to baseline with HiRes. For HINT sentences in noise, the mean
scores for HiRes 120 were significantly higher than scores after subjects were refit with HiRes.
