Official title
Effects of Interaural Frequency and Loudness Mismatch on SSD-CI Performance
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
