Our technology makes hearing easier — especially in noise

Every day you're moving through different hearing environments. Your sound processor should give you the best possible hearing, no matter where you are.

Cochlear™ Nucleus® sound processors feature our latest smart sound processing technology to help you automatically adjust your hearing in any surrounding.

Features include:

  • Dual microphones to help filter out background noise.1

  • Automatic sound processing to help make hearing easier.1-3

  • Technology that helps you hear more clearly during face-to-face conversations when there's background noise.4,5

  • Data logging to give your hearing health professional information about how you use your device for possible program adjustments.

Two synchronised microphones help filter out background noise

Having more than one microphone on your sound processor can help you focus on what you want to hear.

Cochlear's dual-microphones deliver better hearing performance compared to a single microphone.1 The two microphones help automatically filter background noise, so you hear more of what you want.

Sound processors that adapt to your environment – automatically

Our SmartSound® iQ function with SCAN* technology is designed to replicate natural hearing. It captures sound and adapts to your environment without the need for manual adjustments.1-3

How it works:

  1. Dual microphones capture and filter sound.
  2. The industry's first automatic scene classifier, SCAN, analyses your surroundings and identifies the listening environment as one of six scenes, such as quiet, noisy or windy.
  3. The SmartSound iQ function then automatically optimises the sound and adjusts the setting for different hearing conditions to provide your best hearing.

The Nucleus 7 and Kanso 2 Sound Processors also feature ForwardFocus**, an option designed to help you hear better in challenging and noisy environments.4,5

Once your hearing health professional enables ForwardFocus, you switch it on in the Nucleus Smart App when you want to reduce noise coming from behind and focus on the conversation in front of you.

Data logging: vital information for your hearing health professional

Life is busy. Some days it's tough to remember how you're using your sound processor. But data logging technology automatically tracks usage and records the information which can then be accessed by your hearing health professional through programming software.

Your hearing health professional can review the data for trends and important information that shows how the system is working for you.

They can make any adjustments accordingly, to be sure you're always hearing your best.

For parents and carers, data logging adds confidence that your child is getting the most benefit from their Nucleus system.

It also means your hearing health professional can download information about your child’s hearing, such as:

  • How many hours per day you or your loved one is using the cochlear implant.

  • The different sound environments you or your loved one experience in a day.

  • The volume levels you or your loved one use throughout the day.

Track how you or your child hears

Another special feature of the Nucleus Smart App^, the Hearing Tracker feature, gives you direct access to your usage information. This is available with the Nucleus 7 and Kanso 2 Sound Processors.

With the Hearing Tracker in the Nucleus Smart App, you can monitor important information about how you or your child is using the sound processor.

The Hearing Tracker shows:

  • Time in speech: The amount of time you hear in speaking environments is a goal that helps you monitor how you're using your sound processor.

  • Coil Offs: This is the number of times the sound processor was disconnected from the implant on a given day, telling you how many times it was removed.#

It's helpful to establish a baseline number of coil offs to try and minimise them. For parents, you can monitor how often your child removes their sound processor.

* SNR-NR, WNR and SCAN 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.

** ForwardFocus is a clinican-enabled, user-controlled feature. It should only be activated for users 12 years and older who are able to reliably provide feedback on sound quality and understand how to use the feature when moving to different or changing environments. It may be possible to have decreased speech understanding when using ForwardFocus in a quiet environment.
