Reihe: Advances in Oto-Rhino-Laryngology

Electric acoustic stimulation (EAS) combines electric stimulation in the mid- to high-frequency regions with acoustic stimulation in the low-frequency range with the aim to preserve residual low-frequency hearing after cochlear implantation, which together particularly improves speech understanding, pitch discrimination and music appreciation.
