Anatomy-based Fitting in Cochear Implant Users

In this study, the performance with the CI is investigated over time in three groups of freshly implanted CI users. Both the standard frequency-band distribution and anatomy-based fitting will be used to compare outcomes.

In this study, the performance with the CI is investigated over time in three groups of freshly implanted CI users. The first group is fitted using the standard frequency-band distribution as implemented in MAESTRO 9. In the second group of users, an anatomy-based frequency distribution is used as per anatomy-based fitting in MAESTRO 9. The performance with anatomy-based fitting is assessed by comparing performance with the CI in these two groups over time. The third group constitutes the within-subject design. These subjects are both fitting using the standard frequency-band distribution and the anatomy-based frequency distribution in MAESTRO 9. So, subjects will have both study maps on their audio processor throughout the whole study. They will have to change weekly between both fittings: standard fitting and anatomy-based fitting. Here, the performance with anatomy-based fitting is assessed by comparing performance with standard fitting and anatomy-based fitting.
