Implantation With the Nucleus CI532 Cochlear Implant in Adults
The aim of this study is to investigate the clinical benefit for patients implanted with the Nucleus® CI532 cochlear implant.
The Nucleus® CI532 has a pre-curved, perimodiolar array, the EA32, which is introduced into the cochlea through a straightening sheath.

Measure Description |
Time Frame |

|
AzBio Sentence Recognition in Noise
Time Frame: 3 months post-activation
|
The AzBio Sentence test was recorded at 3 months prior to subject withdraw.
Not collected at endpoint.
AzBio 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.

Glasgow Benefit Inventory
Time Frame: 6 months post-activation
|
The Glasgow Benefit Inventory (GBI) is a health utility assessment used at six months post-operatively.
Performance benefits are a change in score from pre- to post-operatively, scored from -100 to +100.

6 months post-activation

Speech, Spatial, and Qualities of Hearing Scale
Time Frame: 6 months post-activation
|
The Speech Spatial and Qualities of Hearing Scale (SSQ) is a subjective measure of satisfaction.
Change is reflected in a gain in scores pre- to post-operatively (-10 to +10).
