Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to assess the effectiveness of an integrated program of fitting and training interventions aimed at reducing unexpected variability and addressing the specific error patterns of each recipient.

The participants will undergo 1 visit lasting approximately 2 hours at the Radboud university medical center's ENT department, where they will undergo a series of diagnostic tests. Some of the participants will also be asked to self-administer additional tests using a Windows tablet.

Based on the outcomes of speech recognition tests in quiet at the first visit, the participants will be called for follow-up interventions concerning both the fitting of their CI and personalized auditory training based on their personal error patterns. These interventions will take place over the course of approximately 5 months and will be made up of three follow-up visits and a period of self-administered training through a mobile application on a tablet.

One final follow-up visit will check whether any changes from the interventions are retained after four weeks.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fitting and Training Intervention

All participants will undergo the full set of diagnostic visits and both Fitting and Training interventions.

The Fitting Intervention is an adjustment of their processors' MAPs based on their error pattern.

The Training Intervention is a personalized training via an app focusing on their most frequent errors.
