What this Trial Is About
Researchers are investigating how people newly implanted with a single-sided deaf cochlear implant (SSD-CI) adapt to different frequency settings. The study aims to understand how adjusting the frequency maps affects sound quality, device usage, and speech understanding. This research focuses on adults with sensorineural hearing loss who are receiving or have recently received a cochlear implant in one ear. Participants will use four different frequency maps during the first month after activation of their cochlear implant. One map is the standard setting, while the other three have progressively higher low-frequency cutoffs. These maps will be alternated daily, allowing participants to experience each setting. After the first month, participants will compare all four maps weekly and choose which one they prefer to use for the following week. Throughout the study, researchers will measure speech perception using tests like the Bamford-Kowal-Bench speech-in-noise test and the consonant-nucleus-consonant word list at multiple time points up to 12 months post-implant activation. Participants will also complete sound quality surveys to provide feedback on their hearing experience. These assessments will help evaluate how different frequency settings impact hearing outcomes over time.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 12 months
Participants use four different frequency maps on their cochlear implant for the first month after activation, alternating daily between a standard map and three experimental maps with higher low-frequency cutoffs. After the first month, participants select which map to use weekly to compare all four maps.
Weekly visits during the first month, then weekly visits for map selection and comparison
