Clearer Speech and Enjoyment of Music

The Most Refined Implant Technology 

As a CI candidate or as a parent of a child who will get a cochlear implant, you want to maximize your or your child’s chances of hearing success. Although it is not exactly possible to predict what and how you will hear with a cochlear implant, your choice of implant may have a big impact. There are no bad cochlear implants, but this is not to say they are all the same. There are significant differences you should be aware of. We believe that each cochlear implant candidate deserves the most refined implant technology for best possible outcomes. This refined technology should make speech as clear as possible and give the best access to music. This is why we developed the HiRes implant technology. HiRes stands for High Resolution, you could also say High Definition.

Why is high resolution important?

Speech is a complex sound that rapidly changes over time in loudness and pitch. Normal hearing people can follow these rapid variations and the human ear sends all the details to a part of the brain called auditory cortex, where the different components (vowels, consonants) are detected, recognized, and interpreted as meaningful speech. Even very subtle information like whose voice it is, or what is the emotional state of the talker is conveyed. All of this is embedded in the tiniest of details of the very complex sound that makes up speech. Speech recognition is important, but to really thrive in life you need to be able to recognize someone’s voice and hear if they are angry, sad, happy or excited.

Music has an even greater variation in intensity and pitch, especially classical music. Cochlear implant technology needs to be very refined to deliver the softest pianissimo just as clear as the loudest crescendo.

So in order to maximize your chances of hearing success, your cochlear implant technology should be able to deliver to your auditory nerve (the hearing nerve) the rapid variations in pitch and loudness, with sufficient detail. So good hearing is about speed, pitch and loudness. Let’s have a look for all three aspects at the HiRes implant technology in comparison to the technology of other manufacturers.


Speed is expressed in the stimulation rate pps, pulses per second. The higher the number, the faster the electronics of the implant deliver sound details to the auditory nerve. From the graph it is clear that the HiRes implant technology is capable of delivering your auditory nerve significantly more pulses per second than any other implant on the market.

The HiRes technology by Advanced Bionics operates significantly faster than any other implant on the market, so you can hear and appreciate more details in complex sound like speech.


Pitch is expressed in the number of (spectral) bands. This can be compared to the number of keys on a keyboard. Each band or key represents a note. The more bands you have, the more keys you may be able to distinguish. From the graph it is clear that the HiRes implant technology is capable of delivering your auditory nerve significantly more bands than any other implant on the market.

The HiRes technology by Advanced Bionics offers significantly more spectral bands than any other implant on the market, so you can enjoy more details of pitch.


Loudness is expressed as the number of dB (decibel) between the softest and the loudest sound your implant delivers to your auditory nerve. That is witthout changing any setting on your implant. From the graph it is clear that the HiRes implant technology is capable of delivering a wider range of loudness than any other implant on the market.

The HiRes technology by Advanced Bionics offers significantly more range in loudness than any other implant on the market, so you an hear and enjoy more variations in loudness.

What does this mean to you? Better Speech Comprehension and Music Enjoyment

The HiRes technology in the AB device allows for access to finer qualities of speech, enabling better speech understanding and music enjoyment. As an adult AB CI recipient you will have the best opportunity to enjoy powerful connections (again); your child, as an AB CI recipient, can have access to the best speech and language development possible with the added benefit of technology that will meet the growing needs of your child. 

Delivering the Details of Sound

When choosing a device, you should consider that the implantable technology can be with you for a lifetime. So, the device you choose should be capable of delivering all of the details you need to enjoy a world of sound. The HiRes cochlear implant from Advanced Bionics was designed to capture the details of sound.

We pushed the limits of technology to provide the most detailed representation of sound because we want you to get the most out of every listening experience.

It's What's Inside That Counts

Internal Components of the AB Cochlear Implant System

Key Features Explained

HiRes™ Ultra 3D Cochlear Implant

Best Overall
Medical Device

1 Electrode Array

Designed for a gentle cochlear insertion, the electrodes deliver 120 spectral bands of sound to help you understand speech and enjoy music.

2  Electronics Package

Advanced technology designed to support current and future generations of sound processors and features.

3  Communication Link

This sophisticated communication link receives digital representations of sound from the external sound processor and sends information about the status of the implant system and your hearing nerve back to the processor.

4  Innovative Multi-magnet Assembly

The multi-magnet assembly in the HiRes Ultra 3D implant allows users to safely undergo high resolution imaging, such as 3.0 Tesla MRI without removing the multi-magnet assembly. Other implants have differing conditions for conducting safe MRI procedures.

Why should I choose the AB Cochlear Implant?

The AB HiRes Ultra 3D cochlear implant offers you:

  • The most detailed sound for better speech recognition and music enjoyment
  • A thin and strong implant with minimal surgical impact and maximum durability for an active lifestyle
  • The ability to benefit from future technology improvements without additional surgery
  • Hassle free and pain free MRI examinations if you ever need them


AB's HiRes Ultra Cochlear Implant utilizes special technologies, designed to accommodate signal processing improvements for decades to come, ideal for the demanding needs of adults and the ever-changing needs of children as they grow.

In the future you will be able to upgrade your sound processor when new listening features become available and expanded capabilities without changing your implant.

Thin and Strong

AB Cochlear Implants are designed to exceed industry standards for impact resistance, allowing you or your child to enjoy life’s adventures without concern.

AB's HiRes Ultra Cochlear Implant is designed to be thin, small, and discreet, making it suitable for adults and children.



MRI is a common imaging technique used in hospitals. This diagnostic equipment generates powerful magnetic fields, and not all medical devices are compatible with this technology. 

AB's newest implant, the HiRes Ultra 3D, allows users to safely undergo high-resolution imaging, such as 3.0 Tesla MRIs, without any preparation, surgery or head bandaging.

Protecting Your Cochlea

Once inserted into the cochlea, the tiny electrode array will be used to stimulate the hearing nerve.

Your surgeon has a choice of electrodes: both designed to protect the delicate cochlear structures and providing complete coverage of the cochlea for full-spectrum sound.    


HiFocus™ Electrodes

The anatomy of each patient is different. Therefore Advanced Bionics offers different electrodes and your surgeon can choose the most appropriate type of electrode for you. Each electrode is designed to provide the best possible hearing.    

HiFocus™ SlimJ

The HiFocus SlimJ electrode features a thin, straight design. It offers full spectrum coverage with a key goal of protecting the delicate structures of the cochlea during insertion.

HiFocus™ Mid-Scala

The HiFocus MidScala electrode is pre-curved for easy placement inside the cochlea. It offers full spectrum coverage with a key goal of protecting the delicate structures of the cochlea during insertion.
