UT Southwestern Testing New Hybrid Hearing Device Combining Advantages of Hearing Aids, ImplantsBy Hearing Review - The Insider,
Publication Date: April 24, 2008
Article describes the DUET Electric-Acoustic System (EAS), a new hybrid hearing aid/cochlear implant device designed for patients who can benefit from both. The device targets borderline hearing-loss patients for whom hearing aids do not adequately distinguish sounds, but for whom some natural hearing remains. The device both amplifies low frequencies and electronically stimulates middle and high frequencies by combining a hearing aid with a cochlear implant. The cochlear implant is surgically inserted into the ear, replacing lost natural hearing by digitizing electrical impulses, sent to the brain via the implanted wires, which the brain interprets as sound. The device is being evaluated at University of Texas Southwestern Medical Center as part of a multisite national study using participants with moderate sloping to severe profound hearing loss who have had minimal results from traditional hearing aids.
