The breakthroughs continue with the Nucleus® 6 System.

Better Than a Hearing Aid1

When a crucial part of your inner ear isn’t working properly, you may need more than a hearing aid. Especially if you have severe to profound sensorineural hearing loss in both ears commonly called “nerve deafness”.

Because all a hearing aid does is amplify sound. It makes everything louder, including background noise. This is where a cochlear implant can really seem like a miracle worker. It’s designed to not only make sounds louder, but clearer.

In fact, a clinical study of Cochlear™ Nucleus® Implant recipients clearly shows the remarkable difference, both in noisy and quiet environments.1

And unlike hearing aids, cochlear implants are covered by most insurance plans, Medicare and typically Medicaid.We also have a dedicated Insurance Support Team that can help you seek insurance coverage or navigate through the appeals process if you are denied coverage.

Enjoy True Wireless Freedom With No Strings Attached

The Nucleus® 6 Sound Processor can introduce you to a whole new wireless world with our 2.4 GHz true wireless technology. You can watch TV, talk on your smartphone and hear speech and conversation – all without the constraints of wires or bulky neck-worn components that you find with less advanced wireless systems. You’ll be able to focus less on hearing and more on what’s important: life...

Cochlear is the first company that provides this truly wireless experience and uses the same 2.4 GHz wireless protocol that Bluetooth® and Wi-Fi devices depend on. That means a clear, secure connection without interference and signal drops. Just pair any one of the Cochlear Wireless Accessories with your Nucleus 6 sound processor for hassle-free audio connections.

The Cochlear Wireless Accessories include the Phone Clip, Mini Microphone and TV Streamer. Learn more about Cochlear True Wireless and Wireless Accessories.

A primary advantage of 2.4GHz is that a third “middle‐man” hub device worn on the body, usually around the neck, is not required. This wireless technology allows the hearing instrument to be the hub that wirelessly connects to an accessory for television, telephone, music players, Bluetooth, etc. ‐ no body worn streaming device is required.1

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.

*SmartSound iQ and Scene Classifier is approved in the US for use only with the Nucleus Hybrid L24 Implant.


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.


Come On In…The Water’s Fine

There’s something soothing about hearing a rock skip across a pond. Or even the calm of a warm bath. So the last thing you need to be worried about around water is your Cochlear Implant. With an IP57* water-resistant rating, the Nucleus® 6 Sound Processor lets you experience the outdoors or relax in the bath. All with added peace of mind.

As a parent, you don't want your kid to miss out on summer activities like swimming at a friend’s house, going to the beach or joining a group trip to a waterpark. The Nucleus 6 Sound Processor allows your child the ability to splash around, play in the waves and go careening down a water slide. All you need to worry about is getting them to put on sunscreen.

And with the simple addition of the new Cochlear Nucleus® Aqua+, the Nucleus 6 Sound Processor is designed to be completely waterproof.** Don’t just stand there, grab your board or your mask and flippers and dive in.

*With rechargeable sound processor battery option. Can be submerged in up to 3 feet of still water for up to 30 minutes. Not intended for swimming.

**The Nucleus 6 Sound Processor with the Nucleus Aqua+ is water resistant to level IP68 of the International Standard IEC60529. This water protection only applies when you use the Nucleus Aqua+ and rechargeable batteries without the acoustic component.

The IP Code is a designation that indicates the level, or amount, of the protection. IP stands for International Protection and the numbers indicate the level of protection. A higher number indicates a higher level of protection.

IP57: Protected against dust particles, sweat and high humidity as well as temporary immersion in water of 3 feet for up to 30 minutes.

The Nucleus 6 Sound Processor also features an innovative water-repellent nano-coating for additional protection.

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 – two times more reliable.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 10 years2
  • Most trusted and chosen Implant with over 350,000 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 


The Perfect Implant For Your Ear

As the creators of the first multichannel cochlear implant, our scientists know the natural curves of the cochlea come in all different shapes and sizes. That’s why they’ve designed the widest range of electrodes to make sure your surgeon can pick the perfect one to give you the greatest sound resolution and coverage in your inner ear.10-12

It’s a proven variety of straight, pre-curved and thin electrode configurations all designed to let you distinguish a greater number of pitches and maximize your hearing performance.13,14


The First Implant Approved For MRI’s Up To 1.5 Tesla

An MRI is an important medical tool. So a cochlear implant shouldn’t keep you from getting one. Our implant has been approved for the most common scan level of 1.5 Tesla with the magnet removed.


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.
