Active Comparator
Place-based map
Default map
CIs will be mapped according to each participant's unique place-based map using MED-EL MAESTRO fitting software. Participants' audiological performance will be assessed in both the experimental and default programs at activation and at 6 months. At 1-month and 3-month visits, performance will be assessed in the participant's assigned program only. Following the 6-month testing interval, participants will listen to the alternative map than the one they were assigned for 1 additional month. At the 7-month visit, participants will be assessed in both programs. After the 7-month visit, participants will be given the choice to move forward with whichever map they prefer. The final assessment interval will take place at 1-year in the participant's chosen map.

At 1-month and 3-month visits, performance will be assessed in the participant's assigned program only. Following the 6-month testing interval, participants will listen to the alternative map for 1 additional month from the one they were randomly assigned. At the 7-month visit, participants will be assessed in both programs. After the 7-month visit, participants will be given the choice to move forward with whichever map they prefer. The final assessment interval will take place at 1-year in the participant's chosen map.
