Speech Processor Programming for Single-Sided Deafness with Cochlear Implant
Trial Summary
What is the purpose of this trial?
Interaural loudness and pitch mismatch in single-sided deaf cochlear implant (SSD-CI) recipients reduces binaural processing cues and contributes to performance outcomes, specifically speech understanding in noise and localization. The study aims to improve binaural cues through speech processor program modifications that reduce interaural mismatches.

Eligibility Criteria
This trial is for adults over 18 with single-sided deafness (SSD) who have normal hearing in one ear and are either experienced users of a Nucleus cochlear implant or will be newly implanted. They must have had postlingual onset of SSD, meaning they became deaf after having learned to speak.Inclusion Criteria
