Electric acoustic stimulation system
Combined electric acoustic stimulation – EAS™
MED-EL is the pioneer of combined Electric Acoustic Stimulation. EAS is a potential solution for partial deafness, known also as high frequency hearing loss. High frequency hearing loss is a type of sensorineural hearing loss, which occurs when the hair cells in the cochlea are missing or damaged. It is different from normal sensorineural hearing loss because the extent of hearing loss varies depending on the sound frequency.
