The DUET Electric-Acoustic System, also known as EAS, is a hybrid hearing device that is currently undergoing trial tests across the US. This product stands to benefit hearing-impaired patients who do not get any help from hearing aids, but cochlear implants are deemed unsuitable because they retain some natural hearing. The EAS caters for borderline cases, specially designed with a thin electrode so that less space is occupied in the inner ear. It will be implanted by special surgical techniques in order to preserve natural hearing, amplifying both low frequencies while electronically stimulating middle and high frequencies. Good to see audio technology advance to such an extent these days.
