Primary | AzBio Sentence Recognition in Noise | 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. | 3 months post-activation | |
Secondary | Glasgow Benefit Inventory | 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 | |
Secondary | Speech, Spatial, and Qualities of Hearing Scale | 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). | 6 months post-activation |
