Superior hearing performance


Nucleus 6 comes with SmartSound iQ which has the widest range of advanced sound processing technologies designed to deliver a superior hearing experience.

Adapts to your environment


Nucleus 6 is the only system with a scene classifier, which analyses the sound environment and automatically applies the right sound processing technology for the best hearing in every situation.

True wireless freedom


Nucleus 6 is the only truly wireless solution that streams audio directly to your sound processor from your TV, phone, or MP3 player, without the need for any intermediary neck-worn devices.

Use natural hearing


Nucleus 6 is the only system with the fully integrated capability to operate both as a hearing aid and a cochlear implant simultaneously, allowing you to make the most of your natural hearing.

Smallest sound processor


As our technology advances, we have worked to make our sound processors even smaller. With Nucleus 6, you now have the choice of the smallest sound processor on the market – the Nucleus CP920.

Most water resistant


Nucleus 6 is the most water resistant behind the ear worn processor on the market. It also has a new water-repellent nano-coating, making it more reliable around water than even before.

Nucleus® 6 Sound Processor

The Cochlear™ Nucleus® 6 Sound Processor works with your cochlear implant to transfer sound to your ear. The Nucleus 6 System is our most advanced hearing solution to date, providing two processors to choose from to help you enjoy simply smarter hearing.

The smallest processor available on the market

We know that sound processor size is important to our recipients, so as our technology advances, we have worked to make our sound processors even smaller. With Nucleus 6, you now have the choice of the smallest sound processor on the market – the CP920.

While it has all the functionality of the CP910, including the capability to connect wirelessly to audio accessories with a future software upgrade, it does not have an accessory port. If you want to use plug in accessories, the CP910 has an accessory port to enable you to do so. Both processors are built from tough materials to withstand even the most active lifestyles.

Unique to Nucleus 6, the CP910 and CP920 sound processors contain a Cochlear-developed chip that is five times more powerful than the chip in our Nucleus 5 System, enabling a range of automated sound technologies (SmartSound iQ) and wireless capabilities.

In addition, if at the time of choosing an implantable hearing solution, you still have some limited hearing, both the CP910 and CP920 sound processors can have the earhook easily changed to accommodate the acoustic hearing aid component to enable the ‘hybrid’ capability unique to the Nucleus 6 System.

Nucleus® 6 Remote Assistant

Manage and monitor your hearing with ease.

While the Nucleus® 6 System is capable of adjusting to your environment automatically, we understand that you may want to get more involved in managing and monitoring your own hearing.

If you’re a parent considering a cochlear implant for your child, the remote assistant can give you the confidence of knowing everything is working as it should.

Cochlear provides two options:


Simple control - CR210 Remote Control

A discrete pocket sized remote control with a handy display screen allows you to adjust simple settings without touching the sound processor.

  • Compact and easy to use.
  • Change programs, volume or sensitivity.

Nucleus® implant portfolio

Cochlear’s range of Nucleus Implants is the result of more than 30 years of ground breaking, collaborative clinical and technical research work.

Our scientists and engineers understand that we all have very different anatomy. That’s why they’ve designed the widest range of implants and electrodes to deliver the best possible sound resolution, coverage and comfort for your unique ear.

Implants designed for your ear

You and your surgeon can now choose from two Nucleus implant series, each offering sophisticated electronics, innovative designs and quality materials.


The most popular implant in the world

The Nucleus CI24RE Series has helped to improve hearing in more than 115,000* ears around the world, and its reliability rating of 99 per cent within 10 years is the best in the Industry.


The thinnest implant in the world

Our latest generation of implants – the Nucleus Profile Series – is the thinnest implant in the world, designed to better conform to the natural shape of the head, making it an ideal choice for you.

A state-of-the art manufacturing facility has been established specially for the Nucleus Profile Series and all of our future generations of implants.

Widest electrode range to suit your hearing needs

Cochlear also offers a distinctive range of electrodes – the part of the implant that sits in the cochlea. With a diversity of sizes and shapes to choose from, your surgeon can find the electrode that best fits your cochlea’s natural curves. What’s more, our electrodes are crafted to help you distinguish more pitches, and experience sound in a more natural way.


MRI at your convenience

MRI scans are a standard medical diagnostic technique and Nucleus implants are designed to fit with your lifelong medical requirements. If you ever need a medium strength MRI up to 1.5 Tesla, you can rest assured that your Nucleus implant allows you to safely undergo the scan with your magnet in place*. And if you need a high-powered MRI up to 3 Tesla*, the removable magnet makes that possible in a simple outpatient procedure too.

How it works

Nucleus 6 is designed to offer people with
moderate to profound hearing loss the best in hearing performance.

With sensorineural hearing loss, sound waves make their way efficiently through the outer and middle ear – just as they do in normal hearing – but then become too soft to detect or too distorted to recognise easily, as a result of damage to the inner ear.

Unlike hearing aids, cochlear implants bypass damaged parts of the inner ear to stimulate the hearing nerve, not with sound waves or vibration, but with precise electrical signals.

Cochlear implant recipients who still benefit from hearing aids may be able to benefit from hybrid hearing – a unique combination of cochlear implant and acoustic hearing, available only with the Nucleus® 6 System. Here is how it works.


How normal hearing works

  1. Sound waves enter the outer ear and travel through the ear canal to the ear drum, causing it to vibrate.
  2. Vibration of the eardrum sets into motion the three small bones of the middle ear, which in turn, transfer the vibration from the eardrum to the inner ear.
  3. The inner ear, also known as the cochlea, senses the vibration and converts it into electrical signals.
  4. The hearing nerve transmits electrical signals from the cochlea to the brain, where they are interpreted as sound.

Hearing with a cochlear implant

  1. Microphones on a sound processor pick up sound waves and the processor converts them into digital information.
  2. This information is transferred through the coil to the implant just under the skin.
  3. The implant sends electrical signals down the electrode into the cochlea.
  4. The hearing nerve fibres in the cochlea pick up the signals and send them to the brain, giving the sensation of sound.

How the acoustic component works

  1. The acoustic component, like a hearing aid, amplifies sounds and sends them via the normal hearing pathway.
  2. At the same time, the processor converts high frequency sounds to digital information which is sent to the implant under the skin.
  3. The implant sends electrical signals down the electrode into the cochlea, stimulating the nerve fibres.
  4. This nerve response is sent to the brain, where it is combined with the response from the amplified sounds from the acoustic component into a perceived sound.
