Experimental: Control first, then Experimental (Group A)
Initial subject use of Control Sound Processing Strategy for the first week, followed by subject use of Experimental (HiRes™ Optima) Sound Processing Strategy for the HiResolution™ Bionic Ear System for the second week.
Device: Control first, then Experimental
Control condition is currently marketed sound processing strategy.
Experimental: Experimental first, then Control (Group B)
Initial subject use of Experimental (HiRes™ Optima) Sound Processing Strategy for the first week for the HiResolution™ Bionic Ear System, followed by subject use of the Control Sound Processing Strategy for the second week.
Device: Experimental first, then Control
Experimental condition is newly modified sound processing strategy.
- Speech Perception With Control and Experimental Conditions Both Tested in Quiet, in Speech-spectrum Noise, and in Multi-talker Babble Noise. [ Time Frame: 2 weeks ]Sentence recognition with the new (experimental) and current (control) sound processing strategies will be compared. Subjects will be tested using the AzBio corpus of sentences, which consists of 33 lists of 20 sentences each (6 to 10 words per sentence) that are equated for intelligibility. The difference between the Control percent correct scores and Experimental percent correct scores will be used for the analysis (Experimental AzBio scores minus Control AzBio scores). Data from both Group A and Group B were pooled for the analysis.
- Device-related Adverse Events [ Time Frame: 2 weeks ]Device-related adverse events will be assessed to determine whether they impact current device safety performance.
