Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Paired difference in AzBio percent correct in noise between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program at a fixed signal-to-noise ratio in the S0N90 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Paired difference in AzBio percent correct in noise between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program at a fixed signal-to-noise ratio in the S90N180 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Paired difference in AzBio percent correct in noise between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program at a fixed signal-to-noise ratio in the S0N180 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Paired difference in AzBio improvement (percentage-point change) for the Nucleus 8 Sound Processor (SCAN 2 FF minus SCAN 2) compared to the Nucleus 7 Sound Processor (SCAN FF minus SCAN) in the S0N180 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Paired difference in CNC percent correct in quiet between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program in the S0 spatial configuration | Week 2 and week 4 | The consonant-nucleus-consonant (CNC) monosyllabic word test will be used to assess speech perception of words in quiet. The test consists of 10 recorded lists of 50 monosyllabic words, produced by a male talker. |
| Secondary | Paired difference in AzBio percent correct in quiet between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program in the S0 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Paired difference in AzBio percent correct in noise between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program at a fixed signal-to-noise ratio in the S0N0 spatial configuration | Week 2 and week 4 | The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words. |
| Secondary | Proportion of participants preferring each sound processor in various listening domains | Week 4 | The Device Preference Questionnaire is a custom self-assessment to evaluate participants' preference between the Nucleus 8 and Nucleus 7 Sound Processors, or "no preference". |
| Secondary | Mean difference in SSQ-12 total scores between the Nucleus 8 Sound Processor and the Nucleus 7 Sound Processor | Week 2 and Week 4 | The SSQ-12 is a validated 12-item abbreviated form of the Speech, Spatial, and Qualities of Hearing scale that measures self-reported hearing ability across speech, spatial, and sound quality domains, with each item rated from 0 (poor) to 10 (excellent). Total scores are calculated by averaging responses across relevant items. |
| Secondary | Mean difference in VFS-A-10 total scores between the Nucleus 8 Sound Processor and the Nucleus 7 Sound Processor | Week 2 and Week 4 | The Vanderbilt Fatigue Scale-10-Item Adult (VFS-A-10) is a validated 10-item subjective scale designed to assess listening-related fatigue in adults with hearing loss. The scale provides a total score based on all 10 questions rated on a Likert scale from 0 (no listening-related fatigue) to 4 (severe listening-related fatigue). |
