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.

Sound Can Change Quickly

Every place is different. With different sounds. One minute you’re walking down a quiet street, the next you’re stepping into a crowded restaurant. You go from a concert hall filled with music to a stadium filled with cheers. And now, thanks to synchronized microphones and SmartSound® technology, you’ll hear your best in all of them.

Unlike most sound processors, the Nucleus® 6 Sound Processor has synchronized microphones that focus on the direction the sounds are coming from, filtering out what you don’t want to hear and tuning in to what you do.

Then the innovative SmartSound technology optimizes the sound to enhance your hearing in any environment, including ones filled with music or background music.

If you prefer to have more control over your hearing, you have the choice of using the sound processor or the remote assistant to make simple modifications to your hearing so you hear your best in any situation.

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.

Aqua+ Sweat - Nano - Shower - Rain

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.

Aqua+ Swim - Surf - Snorkle (horizontal icon)

*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.


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.


It’s A Whole New Wireless World

Just being able to use the phone like everyone else is life-changing. That’s why our Nucleus® 6 Sound Processor comes with a telecoil so you can talk on the phone without plugging anything else in. But that’s just the beginning. The Nucleus 6 Sound Processor has a chip that’s 5 times more powerful than our previous sound processors. And soon, you’re going to be able to put all that processing power to good use.

With a simple software upgrade that’s under development*, your Nucleus 6 Sound Processor will directly connect to an incredibly wide range of 2.4GHz wireless devices . You’ll use Bluetooth-enabled music players and some hearing aids without any wires, ear buds or additional accessories hanging around your neck. The audio signals from your TV, stereo and GPS will broadcast right to your sound processor, just like it was an extra speaker. Whatever wireless wizardry they come up with, you’ll probably be able to connect to it.

*FDA-approved for the Nucleus 6 Sound Processor; available February, 2015.

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
