Learn About the Innovative Features & Benefits of the Nucleus® 6 System

Experience Clearer Sound and A Lifetime Of Better Hearing

When a crucial part of your inner ear isn’t working properly, you may need more than a hearing aid, especially if you have moderate to profound hearing loss in both ears, which is often misunderstood as "nerve deafness". This type of hearing loss can make speech more difficult to understand, especially in noisy situations.

Hearing aids often do not benefit you if you have this type of hearing loss because a hearing aid can only amplify the sounds you hear, including background noise. A cochlear implant is designed to make sounds not only louder but also clearer by replacing the function of the damaged inner ear. In fact, a clinical study of Cochlear Nucleus Implant users clearly shows the remarkable improvement in noisy environments.1

With cochlear implants, you may get back the sounds you’re missing and once again enjoy conversations with family and friends, talk on the phone, enjoy music and hear the sounds of nature.

Covered by Insurance

Unlike hearing aids, cochlear implants are covered by most insurance plans, Medicare and typically Medicaid.* We have a dedicated Insurance Support Team that can help you navigate the appeals process if you are denied coverage. Find more information here.

*Contact your insurance company or local Hearing Implant Specialist to determine your eligibility for coverage.

A Sound Processor That Adapts To Your World – Automatically

Every place is different, with different sounds. One minute you could be walking down a quiet street and the next, you’re stepping into a crowded restaurant. You’re constantly moving into different listening environments, and you want your sound processor to adapt to all of them – effortlessly. Our SmartSound® iQ* and dual-microphone technologies are designed to do just that.

The Nucleus 6 Sound Processor has the world’s first Scene Classifier in the cochlear implant industry that automatically scans your surroundings and identifies the listening environment as one of six scenes. SmartSound iQ then adjusts the setting for that scene to provide you optimal hearing for that situation without the need for manual adjustments to the sound processor. It’s this advanced technology that makes the Nucleus 6 Sound Processor simply smarter.

*SNR-NR and WNR are approved for use with any recipient ages 6 years and older, who is able to 1) complete objective speech perception testing in quiet and in noise in order to determine and document performance 2) report a preference for different program settings. SCAN is FDA approved for use with any recipient age 6 years old and older, to be used at the discretion of the recipient/parent/caregiver.


A Processor So Smart, It Can Tell You Where It’s Been

It can be hard to remember what happened yesterday, let alone the last month. With data logging, you don’t have to. It records exactly how your sound processor is being used every day. It fills in all the gaps, so your audiologist gets a more complete picture of your hearing experiences, and makes any necessary adjustments so you can hear your best.

For parents, the data logging functionality provides added confidence that your child is hearing their best at all times. For the first time ever, key information about your child’s Nucleus® System can be downloaded by your audiologist for evaluation.This is a minute-to-minute, comprehensive record that lets the audiologist know how your child is using the system and if it’s being used correctly, especially when you cannot be with them.

Cochlear Is #1 In Reliability2-7

When you’re considering a cochlear implant, you want to know all the facts, especially when it comes to the reliability of the implant you are choosing. The fact is, our Nucleus CI24RE Cochlear Implant is more reliable than anything else available today.2-4

What’s more important is reliability over time. We design our Cochlear Implants to last a lifetime, and our long-term reliability records reflect that.

  • Our Nucleus CI24RE Cochlear Implant boasts a 99% reliability rating at 11 years2
  • Most trusted and chosen Implant with over 450,000 devices implanted worldwide8,9

All cochlear implant manufacturers have demonstrated the capability to build a reliable implant for one year, but only the Nucleus Implant has demonstrated a strong reliability rating over time.2 


An Implant Designed Just For You

The internal cochlear implant is made of up two primary components: the implant receiver and the cochlear electrode array.

  1. The implant receiver, placed just under the skin, converts the digital sound signals picked up from the external sound processor and sends them down the electrode.
  2. The electrode is inserted into the cochlea, stimulates the cochlea through “contacts” and sends impulses directly to the hearing nerve where they are perceived as sound.

As the creators of the first multichannel cochlear implant, we understand the need for advanced options of implants and electrode arrays. Our scientists know the natural curves of the cochlea come in all different shapes and sizes which is why they’ve designed a wide range of electrodes to make sure your surgeon can pick the appropriate one to give you the greatest sound resolution and coverage in your inner ear.10-12

In addition to our range of electrode arrays, we also offer the Nucleus® Profile Implant - the thinnest implant available13-15. The Profile contours the curvature of the head for added comfort, and is very impact resistant. The Nucleus Profile further expands what is the industry's largest cochlear implant portfolio and provides surgeons more choices to fit your needs.


Safety Matters With MRI

Magnetic Resonance Imaging (MRI) is a common medical imaging procedure. MRI machines use a powerful magnet to provide detailed images of a person’s internal organs and tissue. Because of this powerful magnet, 97% of radiology professionals surveyed do not recommend MRI scans for patients with magnets in their body.16

In fact, 85% of radiology professionals agree they have an alternate diagnostic tool for patients who cannot undergo an MRI due to having a device or implant with a magnet.16 However, on the rare occasion that you may need an MRI, you can have the peace of mind that Cochlear™ Nucleus® Implants are compatible with an MRI of 3.0 Tesla with the magnet removed. If it is desired to keep the magnet in place, Nucleus Implants are also approved for an MRI of 1.5 Tesla with the magnet in, using our MRI Kit.

There are risks in keeping the internal cochlear implant magnet in place during an MRI which is why we believe the gold standard is to remove the magnet.

Risks involved with leaving the magnet in during an MRI include:

  • Pain or discomfort during the MRI procedure17
  • Pulling or movement of the magnet underneath the skin17 which could put the placement of the internal electrode at risk
  • Reversal of magnet polarity or demagnetization17 requiring a procedure to replace the magnet
  • Decreased quality of the MRI image due to shadow that the implant magnet may cast on the desired area18

Because of these risks, we have designed our implants specifically for safe and easy magnet removal.

Cochlear Nucleus Implants are designed with the safety and comfort of the patient in mind, today and into the future. That’s another reason why more people choose Cochlear than all the other hearing implant companies combined.8,19


Hear Your Best – In Both Ears

Hearing with both ears offers a clear advantage, especially when it comes to distinguishing where sound is coming from and understanding speech in noisy environments.

Depending on your degree of hearing loss, you may benefit from bimodal hearing, which is using a hearing aid in one ear and a cochlear implant in the other ear. Or, you may find it more beneficial to have a cochlear implant in both ears (bilateral cochlear implants). With both bimodal hearing and bilateral cochlear implants, you may find that understanding speech is much easier, and that you’re able to enjoy a more complete hearing experience, especially in noisy environments.

For those individuals who have a Cochlear Implant in one ear and still receive benefit from a hearing aid in the other ear (bimodal hearing), Cochlear has partnered with GN ReSound to pioneer the world’s smartest bimodal hearing solutions with SMARTstream™ technology.


The Breakthroughs Will Continue

No one has advanced the science of hearing implants longer than Cochlear. Or pushed it further. And those advancements will continue.

To further our focus on innovation, we built the largest hearing research and development center in the world. Sound processors will become more and more powerful, even as they continue to get smaller and smaller. We design our sound processors so you will be able to upgrade to future technologies. That's the promise we make when we say, "Hear now. And always".

30 years and five sound processor upgrades later, one of our first patients is living proof of our lifetime commitment to you.

Graham Carrick is profoundly deaf. And yet he can hear, thanks to the cochlear implant he got in 1982. Since that remarkable day when he heard his daughter’s voice for the very first time, Graham’s life has never been the same. Everything is so much better than he ever dreamed. We’re proud to say we were with him every step of the way.

And we’ll be there with you, too.
