Group Intervention Description Nucleus Hybrid L24 Implant Nucleus Hybrid L24 Implant Adults age 18 and over who meet FDA criteria for unilateral implantation with the Nucleus Hybrid L24 Implant.
- Primary Outcome Measures
Name Time Method Change in Consonant-Nucleus-Consonant (CNC) Word Recognition in Quiet for the Two Listening Conditions: Implant Ear Alone and When Using Both Ears Together From Pre-operatively Through 3 Years Post-activation of the Device From pre-operatively through 3 years post-activation of the device The CNC Words test consists of 10 recorded lists of 50 monosyllabic words in CD format. For this study, two lists will be administered in quiet at a level equal to 60 dBA in the sound field and recorded as a total number of words correct, which will be expressed as a percentage correct for this study. The CNC word test has a score range of 0-100% with higher values indicating better scores.
Number of Device or Procedure Related Adverse Events Up to 5 years post-activation of the device
- Secondary Outcome Measures
Name Time Method Change in AzBio Sentence Recognition in Noise in the Best Unilateral Condition Pre-operatively, up to 3 years post-activation of the device The AzBio Sentence Tests consists of 15 lists of 20 sentences each. AzBio sentences are spoken by different talkers in a conversational style with limited contextual cues that the listener can use to predict or 'fill in' unintelligible words. Each list includes 5 sentences from 4 different male and female speakers. Each word in the sentence counts toward the overall score and the resulting score is presented in percent correct. The AzBio sentence test has a score range of 0-100% with higher values indicating better scores.
