The purpose of this study is to evaluate the impact of different audio processor frequency settings on performance outcomes in new cochlear implant users using electric-only stimulation in the implanted ear with normal hearing to moderately severe hearing loss in the opposite ear.
Participants will be randomized into a starting frequency setting at device activation or shortly after device activation for the first three months of device use. After 3 months listening experience, participants will be randomized into different frequency settings and tested before and after a period of listening experience. Participant outcomes for each of the multiple frequency settings will be evaluated using standard clinical speech testing and through questionnaires designed to capture information about patient sound quality and quality of life.
* At least 18 years of age * Is a cochlear implant candidate as deemed by the participating center * Implanted (or to be implanted) unilaterally with a MED-EL cochlear implant with moderately severe or better acoustic hearing in the contralateral ear. * For patients who are already implanted, device activation must have occurred within 2 weeks of enrollment * Patients with moderate contralateral hearing loss or greater must utilize a hearing aid in the contralateral ear. * Programmed with electric-only stimulation in the implanted ear * The ear to be implanted, acoustic hearing thresholds must…
Cochlear implant audio processor frequency settings will be adjusted within the clinical programming software
