About this study
Official title: Evaluating Design Improvements With SONNET 3 in Experienced Cochlear Implant Users
Measuring user-reported satisfaction with the latest behind-the-ear (BTE) audio processor model.
Read the detailed description
This prospective study will use a single-arm, repeated measures design with subjects serving as their own control. Participants will be experienced cochlear implant (CI) users wearing an approved BTE MED-EL audio processor. Participants will complete a take-home trial with the latest audio processor and then complete a custom questionnaire comparing design and usability to their existing audio processor.

What is being measured
The primary outcome is the main question the study is designed to answer.
Participants Reporting Improvement With SONNET 3 Design
The proportion of participants reporting improvement in design aspects of SONNET 3 (EAS) on a user survey
Measured: Measured 1 month after baseline
Secondary outcomes (1)
Audiologist Satisfaction Ratings
Score on a 6-point Likert scale (1 = Strongly Disagree to 6 = Strongly Agree; higher scores indicate better outcomes). Values reported are the average scores on subsections of the audiologist survey.
Measured: Measured after study completion, an average of 7.5 months
