About this study

The study will determine if electrode length and coding strategy effect performance. The investigator will also study performance over time with new recipients.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • MED-EL current cochlear implant recipients of the Flex 24 or 28 will be included
  • Minimum of 6 months experience with their cochlear implant
  • Minimum of 10 new adult Med-El recipients of the Flex 24 or Flex 28 electrodes
  • Patient at the University of Miami

Exclusion criteria

  • Adults unable to consent
  • Individuals who are not yet adults (infants, children, teenagers)

Treatment and study plan

Simulated reverberant environment

Other

Reverberant environments simulate real-life situations mimicking a living room, classroom and auditorium. Each simulation lasts up to 2 hours.

Primary outcomes

  1. Speech Performance

    Time frame: Up to six months

    Speech performance recorded as percent correct compared to different electrode lengths.

  2. Coding strategy

    Time frame: Two hours

    Speech scores, in percent correct, recorded from simulated reverberant speech tests will be compared between fine structure and envelope coding strategies.
