Candidacy for Electric
Acoustic Stimulation (EAS)
Who Can Benefit from EAS?
EAS is especially designed to suit the needs of individuals with high-frequency hearing loss. High-frequency hearing loss 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 high-frequency hearing loss—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.
