Summary
"This trial aims to gather information from patients who have recently received a cochlear implant to improve the way the implant is programmed for better results."
Who is the study for?
This trial is for adults over 18 who became deaf after age 2 and now have a CI600 or CI500 series cochlear implant. Participants must understand the language used in speech tests and agree to follow the study rules.
What is being tested?
The study compares two ways of setting up cochlear implants: one uses behavioral fitting with Custom Sound Suite software, and the other uses loudness scaling with Nexus System. It's to find out which method works best post-activation.
What are the potential side effects?
Since this trial involves programming methods for cochlear implants rather than drugs, traditional side effects are not applicable. However, participants may experience differences in hearing quality or comfort levels with each fitting approach.
