Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals who have been implanted with a MED-EL cochlear implant for at least 12 months and are currently using a SONNET or SONNET 2 audio processor.
✕Probably not a fit
Patients with retrocochlear hearing loss or those unable to provide reliable feedback during programming may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This prospective study evaluates user satisfaction with the latest behind-the-ear audio processor model among experienced cochlear implant users. Participants will wear the new MED-EL audio processor and complete a custom questionnaire to compare its design and usability against their current processor. The study employs a single-arm, repeated measures design, allowing participants to serve as their own control. This approach aims to gather direct feedback on the new device's performance and user experience.
Why it matters
Potential benefit: If successful, this study could lead to enhanced audio processing technology that improves the quality of life for individuals with hearing loss.
How similar studies have gone: While this specific approach is novel, similar studies evaluating user satisfaction with audio processors have shown promising results.
