About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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.

Primary outcomes

  1. Participants Reporting Improvement With SONNET 3 Design

    Time frame: Measured 1 month after baseline

    The proportion of participants reporting improvement in design aspects of SONNET 3 (EAS) on a user survey

Secondary outcomes

  1. Audiologist Satisfaction Ratings

    Time frame: Measured after study completion, an average of 7.5 months

    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.
