Official Title: Iowa Cochlear Implant Clinical Research Center Hybrid Cochlear Implants in Severe to Profound Adults, Children, and Adolescents
Brief Summary: The purpose of this study is to determine if adults and children with residual low-pitch hearing in the severe hearing loss range can develop improved speech perception by combining their residual acoustic hearing with electrical stimulation through a short cochlear implant. The low-pitches would be amplified with a hearing aid and the high-pitch sounds would be stimulated electrically.
