Iowa Cochlear Implant Clinical Research Center Hybrid Cochlear Implants in Severe to Profound Adults, Children, and Adolescents
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
