Our technology makes hearing easier — especially in noise

Every day adults and children are moving through different hearing environments. Their sound processor should give them the best possible hearing, no matter where they are.

Cochlear™ Nucleus® sound processors feature our latest smart sound processing technology to help adults and children automatically adjust their hearing in any surrounding.

Features include:

  • dual microphones to help filter out background noise

  • automatic sound processing to help make hearing easier

  • technology that helps adults and children hear more clearly during face-to-face conversations when there's background noise

  • data logging to give a hearing health professional information about how adults and children use their device for possible program adjustments.

Two synchronised microphones help filter out background noise

Having more than one microphone on a sound processor can help adults and children focus on what they 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 adults and children hear more of what they want.

Sound processors that adapt to the environment – automatically

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

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 the best hearing.

The Nucleus 7 Sound Processor also features ForwardFocus — an option designed to help adults and chidlren hear better in challenging and noisy environments.

Once a hearing health professional enables ForwardFocus, an adult or child can switch it on through their Smart App when they want to reduce noise coming from behind and focus on the conversation in front of them.2,3

Data logging: important information for a hearing health professional

Life is busy. Some days it's tough for adults and children to remember how they're using their sound processor. But data logging technology automatically tracks usage and records the information.

A hearing health professional can review the data for trends and important information that shows how the system is working for an adult or child.

They can make any adjustments accordingly, to be sure the adult or child is always hearing their best.

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

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

  • how many hours per day they're using the cochlear implant

  • the different sound environments they experience in a day

  • the volume levels they use throughout the day.

Track how an adult or child hears

Another special feature of the Nucleus Smart App+, the Hearing Tracker feature, gives direct access to usage information. This is available with the Nucleus 7 Sound Processor.

With the Hearing Tracker in the Nucleus Smart App, adults and children can monitor important information about how an adult or child is hearing with the sound processor.

Some benefits to the Hearing Tracker include:

  • Time in speech: The amount of time adults and children hear in speaking environments is a goal that helps them monitor how they're using their sound processor.

  • The Hearing Tracker monitors an adult or child's time in a speaking environment and more easily tracks their time in speech against your goal.

  • Coil Offs: This is the number of times the Nucleus 7 Sound Processor coil was disconnected on a given day, telling an adult or child how many times it was removed.

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