It's your moment.
Are certain sounds easier to hear than others? Can you hear male voices, but struggle to hear female voices? Do you feel that your hearing aids are just not good enough?
If this sounds familiar, you may be missing out on hearing high-frequency sounds. When you cannot hear high-frequency sounds, you might have a type of hearing loss known as Partial Deafness. Partial Deafness is common in both children and adults.
EAS is the combination of two technologies: a cochlear implant for the high frequencies, and acoustic amplification for the low frequencies. Together, they cover the full range of hearing for both children and adults.
EAS can help you to regain hearing in both the low and high frequencies of sound. This is an example of an audiogram indicating how your hearing might improve with EAS.
The red line shows how acoustic amplification can improve your residual hearing in the low frequencies, and the blue shows the significant improvements in high-frequency hearing that electric stimulation provides.
Together, these technologies combine and can help you to hear all the sounds of speech.
Switching from hearing aids to EAS has proven benefits. Five independent studies demonstrate significant improvement in the hearing of children and adults with Partial Deafness after switching from hearing aids to EAS.
The graph shows the results of post-operative monosyllable speech score tests. EAS users score an average of 50 percentage points higher in speech understanding and sound quality when compared to their preoperative use of hearing aids.
The SONNET EAS is the 3rd generation Electric Acoustic Stimulation (EAS) Audio Processor from MED-EL, the pioneer of combined Electric Acoustic Stimulation. SONNET EAS combines the SONNET audio processor with an acoustic unit and customised ear mould to provide dedicated acoustic stimulation across the low frequencies and electric stimulation in the high frequencies. With 48dB acoustic amplification across the low frequencies, SONNET EAS is the ideal solution for candidates with partial deafness.
With dual microphone technology, SONNET EAS features Automatic Sound Management 2.0 for hands-free control and effortless listening wherever you go. The water-resistant and lightweight SONNET EAS is designed for all-day comfort and security.More about the SONNET EAS Watch the video

MED-EL offers the widest selection of soft, flexible electrodes to ensure the optimal solution can be chosen for every candidate.
The SYNCHRONY EAS Hearing Implant System is specially designed for individuals with partial deafness. Partial deafness is mild to moderate low-frequency hearing loss combined with profound hearing loss in the higher frequencies.
Candidates for an EAS Hearing Implant System undergo audiological tests and medical examinations to determine whether EAS is a suitable treatment for them. The audiological tests assess the degree of hearing loss both in low and in high frequencies.
The SYNCHRONY Cochlear Implant, the internal part of the SYNCHRONY EAS System, is implanted under the skin behind the ear. The surgery is a routine procedure for experienced ENT surgeons and usually takes one to three hours. Your surgeon will advise you concerning any additional details of the surgery.
Between two and six weeks following implantation, both the electric stimulation and the acoustic amplification of the EAS Hearing Implant System are activated. An initial period of adaptation to the combined stimulation is common and should be expected.
