Candidacy for Electric
Acoustic Stimulation (EAS)

Combined Electric Acoustic Stimulation (EAS) uses acoustic amplification
and cochlear implant technology (electric stimulation) together in the same
ear. It is the ideal solution for individuals with partial deafness. MED−EL encourages individuals with partial deafness to learn more about the
EAS Hearing Implant System and the difference it can make in improving
quality of life.

Who Can Benefit from EAS?

EAS is especially designed to suit the needs of individuals with partial deafness. Partial deafness is characterised by residual hearing in the low frequencies and a significant high frequency hearing loss.

EAS provides acoustic stimulation that supports a person's natural residual hearing by amplifying the low frequencies. For higher frequency sounds, the integrated cochlear implant technology automatically takes over and supplies the appropriate electric stimulation to the neural structures.


EAS is designed for people who:

  • have been diagnosed with partial deafness, a mild to moderate sensorineural hearing loss in the low frequencies sloping to a profound hearing loss in the higher frequencies.
  • receive little or no benefit from hearing aids.
  • experience inadequate speech comprehension, even in the best aided condition.
