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

I am 18 years old or older.
Implanted with or chosen to be implanted with a Nucleus cochlear implant
I am an adult with hearing loss in one ear.

Treatment Details

Interventions

  • Treatment-modifications to CI speech processor program
Trial OverviewThe study tests modifications to the speech processor program of cochlear implants in individuals with SSD. The goal is to improve binaural cues which help with understanding speech in noisy environments and sound localization by reducing loudness and pitch differences perceived between ears.
