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.
