Our technology makes hearing easier—especially in noise

Every day you’re constantly moving through different environments—and your sound processor should adapt to all of them automatically. The Cochlear™ Nucleus® Sound Processor portfolio features our latest smart sound processing technology to help you hear your best in those different environments, including:

  • Dual microphones that help filter out background noise.

  • Automatic sound processing to help make hearing easier.

  • Data logging to help provide key usage information to your audiologist for possible program adjustments.

Two synchronized 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. You can experience better hearing performance, particularly in noisy environments1 with Cochlear’s dual-microphone zoom technology.

This technology helps automatically filter out background noise and optimize your hearing experience. Two synchronized microphones work together to reduce sound from behind and to the sides so you hear more of what you want, making it easier to recognize speech, even in noisy environments.1

Sound processors that adapt to your world—automatically

Our innovative SmartSound iQ* with SCAN technology is designed to replicate natural hearing by capturing sound and automatically adapting to your environment without the need to make manual adjustments.

How it works:

  1. The dual microphones first capture and filter sound
  2. The industry’s first automatic scene classifier, SCAN, analyzes your surroundings and identifies the listening environment as one of six scenes
  3. SmartSound iQ* then automatically optimizes the sound and adjusts the setting for that scene to provide your best hearing

In addition to the automatic features of SCAN, the Nucleus Sound Processors feature ForwardFocus,** which is designed to help you hear better in challenging environments.

Once enabled by your clinician, simply switch on ForwardFocus through the Nucleus Smart App when you want to decrease noise coming from behind you and focus on the face-to-face conversation in front of you.

Data logging provides key information to your audiologist

Life is busy. Some days it’s tough to remember the details of how you’re using your sound processor. That’s why ours feature innovative data logging technology, which records detailed usage information. Your audiologist can review the data for trends and important information that will show how the system is working for you. This can guide your audiologist in making any adjustments—all to make sure you’re always hearing your best.

For parents, the data logging functionality provides added confidence that your child is hearing their best at all times. Your audiologist can download key information about your child's Nucleus® System. This allows the audiologist to know how the system is being used including number of hours per day the cochlear implant is used, different sound environments experienced in the day and the volume levels that were in use.

There is also a special feature of the Nucleus Smart App, called the Hearing Tracker, which is available with the Nucleus Sound Processors and gives you direct access to your personalized usage information.
