Electric Acoustic Stimulation

Electric Acoustic Stimulation (EAS) is the concept of using hearing aid and cochlear implant together in the same ear. The hearing aid acoustically amplifies low frequencies, while the cochlear implant electrically stimulates the middle and high frequencies. The inner ear processes acoustic and electric stimuli simultaneously.

Results of international studies show a highly synergic effect between hearing aid and cochlear implant technology, particularly evident in speech understanding in noise and music appreciation.
