Study Summary
Purpose: Investigate monaural and binaural hearing in electric-acoustic stimulation (EAS) users with place-based versus default maps. Participants: Cochlear implant recipients and normal-hearing listeners Procedures (methods): This is a prospective, longitudinal investigation of the monaural and binaural outcomes (such as speech perception, spatial hearing, and/or subjective benefit) of cochlear implant recipients listening with different programs. The programs will incorporate different patient and device variables to determine the effect on cochlear implant recipient outcomes.
Primary Outcome
Monaural perception (e.g., word recognition in quiet) will be assessed at defined intervals (e.g., activation, and 1, 3, 6, and 12 months post-activation). Performance (e.g., percent correct) will be compared within-subject and between group over the study intervals. This procedure is specific to Arm 1 (participants with default maps) and Arm 2 (participants with place-based maps).
Interventions
- OTHER place-based mapping
- OTHER default mapping
