Design Improvements With SONNET 3

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.

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.

Inclusion Criteria:

• Implanted with a MED-EL cochlear implant in at least one ear
• ≥ 12 months since activation of the MED-EL audio processor
• Consistently using a SONNET (EAS) or SONNET 2 (EAS) Audio Processor
• Ability to complete all study procedures
• Participant and parental (if applicable) commitment to comply with all study procedures for the duration of the study

Exclusion Criteria:

• Evidence that hearing loss is retrocochlear in origin
• Unable to provide reliable feedback during cochlear implant programming
• Skin or scalp condition precluding use of the study device
• Unrealistic participant or parent (if applicable) motivation or expectations
• Participants without a stable fitting map at enrollment e.g., due to changes in hearing, global health status, etc.
