MED-EL SYNCHRONY System

Our Philosophy

When your patients look for a cochlear implant, they don’t want a device or a technology. They want a solution to a problem. They want to unlock their potential, reach for every opportunity, and to hear life to the fullest.

That’s why our design philosophy is to provide the closest match to natural hearing from the ground up—creating a hearing experience that no other cochlear implant can match.

Our philosophy is to adapt the implant to your patient, instead of adapting your patient to the implant. Our individualized cochlear implants offer the closest to natural hearing in each cochlea from the very beginning—enabling each recipient to experience MyBest™ Hearing. With MED-EL, your patients can enjoy hearing life like it was meant to be heard.

We didn’t stop at the best hearing performance. We want every recipient to have the best possible hearing experience in their everyday lives. That’s why we design our audio processors to provide intuitive handling, stylish designs, and all-day wearing comfort. Wireless charging, Bluetooth® connectivity, water-resistant designs—our processors are made for real life

Choosing a cochlear implant is a life-long decision. Through all life’s bumps and bruises, MED-EL will be there for your patients. We created a one-of-a-kind magnet to deliver outstanding MRI safety*. Our robust titanium cochlear implants deliver proven long-term reliability that your patients can always count on.

Only MED-EL delivers the proven combination of superior hearing performance, ease of use, and peace of mind that every recipient deserves.

Cochlea Structure

Closest to Natural Hearing

Above all else, the purpose of a cochlear implant is to create the most useful interface between the electrode array and the neural structures of the cochlea. Every single element that goes into a cochlear implant culminates in this intricate bridge between technology and nature.  

How do we provide the most natural hearing possible with a cochlear implant? By engineering our electrode arrays to most closely match the precise natural design and function of the cochlea. 

Our incredibly flexible electrode arrays protect the delicate structures in the cochlea, enabling atraumatic insertion all the way to the apical region. This allows our full-length electrode arrays to provide two full turns of Complete Cochlear Coverage, which maximizes the natural tonotopic stimulation range. Finally, our unique variable-rate FineHearing sound coding is the only sound coding that mimics the temporal phase-locking in natural hearing for a sound quality that no other cochlear implant can match.  

 Closest to Natural Hearing

We deliver the closest to natural sound quality for a hearing experience that no other cochlear implant can match.

 Intuitive Handling

We offer intelligent and intuitive audio processors available for outstanding performance and ease of use.

 Peace of Mind

Our implants are engineered for the highest safety and long-term reliability for years of performance and true peace of mind.

Natural Loudness Growth

Our Dual-Loop Automatic Gain Control instantly adapts volume levels to make loud sounds more comfortable and soft sounds easier to hear. With an extended loudness growth range and compression ratio (3:1), our loudness growth more closely follows natural loudness growth in the cochlea. 

This is an advantage for loudness balancing with bilateral CIs, or if the other ear has natural hearing, such as single-sided deafness or for bimodal listening with a contralateral hearing aid.


Microphone Directionality

SONNET 3 uses Microphone Directionality to mimic the natural pinna effect by reducing sounds behind and focusing to the front of the listener. This enables significantly better hearing performance in noisy environments.

Natural directionality provides significant advantage in everyday life, and Adaptive directionality provides a powerful boost in complex noise.


Structure Preservation

Our incredibly flexible lateral wall arrays can gently adapt to the shape of each individual cochlea to protect the delicate natural structures. Multiple recent studies have shown only MED-EL arrays enable 100% scala tympani insertions. 

Scala tympani placement enables significantly better hearing outcomes. Our gentle arrays also enable hearing preservation, for combined electric-acoustic stimulation with SONNET 3 EAS.

Complete Cochlear Coverage

In natural hearing, the nerve fibers of the spiral ganglion are tonotopically organized and extend the full length of the cochlea. If an electrode doesn’t cover two full turns (720°) of the cochlea, it can’t stimulate these nerve fibers to provide accurate pitch-place match.  

Our long, flexible arrays can be safely inserted all the way to the apical region to provide natural tonotopic stimulation across two full turns of the cochlea. With complete cochlear coverage, recipients can enjoy a natural pitch match from the very beginning. This enables significantly better hearing performance and a more natural hearing experience for your patients.

FineHearing Sound Coding

In nature, the cochlea uses two types of sound coding. Place-pitch tonotopic coding is used along the whole frequency range. In addition to place-pitch coding, low-frequency sounds are also coded by rate. With this time-coding, the frequency of nerve signals is synchronized to the frequency of the sound below ~1000 Hz.

That’s why we created the only cochlear implant sound coding that mimics the natural time-coding for low frequencies and provides place-pitch match throughout the cochlea. By mimicking natural sound coding, FineHearing provides much more natural sound quality.

Benefits: Music

Music is a complex form of sound, making it one of the most challenging things to listen to. So when recipients can enjoy listening to music, you know they’ve reached a whole new level of hearing.

Benefits: Sound Localization

Whether it’s a noisy classroom or a busy sidewalk, knowing where a sound is coming from is essential for your patients. By providing more accurate interaural time differences (ITDs) and interaural level differences (ILDs), our cochlear implants enable more accurate sound localization than any other cochlear implant. 

Audio Processors

Intuitive Audio Processors

MED-EL Audio Processors
For your patients, their audio processor is the most tangible part of their cochlear implant system. It’s the first thing they put on in the morning and the last thing they take off at night. Rain or shine, it’s with them every minute of the day. That’s why our audio processors are made for everyday life. 

Our audio processors combine hands-free control with lightweight, water-resistant designs. Our Automatic Sound Management technology seamlessly adapts to changing listening environments for optimal hearing in any environment. With rechargeable batteries, stylish designs, and wireless connectivity, our audio processors are the right fit for every user.

And we design our new audio processors to be fully compatible with our previous implants, so recipients can easily upgrade to benefit from the latest technology. Whether it’s at work or on the playground, our audio processors are made to deliver exceptional comfort and hearing performance that your patients can always rely on.
