Hear More of Your World

In today’s smaller-is-better world of consumer electronics, some cochlear implant manufacturers focus on the size of their systems. While size matters, it’s the technology inside that delivers the vibrant world of sound.


AB offers the most cutting-edge, sophisticated sound processing for high-performance hearing. This upgradeable technology is designed with one unwavering goal in mind: to help you or your child hear your best in virtually any environment, from a quiet office cubicle to a loud classroom.

“Despite profound hearing loss from birth, I was able to hear my name being called right after my activation, able to repeat words and sentences back to my audiologist without any visual cues on day one. I heard my feet hitting in the sand while walking on the beach, and while driving I listened to songs on the radio.”

Debbie Bottles, AB recipient

Superior Technology = Superior Hearing

Performance matters. That’s why all of AB’s exclusive, sophisticated sound-processing technologies are designed to help you or your child to hear your world in the greatest possible detail. The more sound strategies offered, the more options you have for hearing. Only AB provides seven sound coding strategies to help you hear your best.

The World of Sound in Detail

AB’s state-of-the-art cochlear implant technology has been developed to help your child or you hear all of your world—from the quietest listening environment to the most challenging noisy setting. An industry first, now AB also has exclusive access to Phonak Binaural VoiceStream Technology™ designed for improved hearing in noise.

Phonak Binaural VoiceStream Technology™

For the first time in history, cochlear implant recipients have access to the combined technologies of AB and Phonak, the innovation leaders in cochlear implants and hearing instruments. Naída CI Q70 (Naída CI) offers exclusive Phonak Binaural VoiceStream Technology™ to help recipients hear speech better in noise, and take the strain out of conversations. Delivering a breakthrough in bimodal hearing, AB launches another market first as the only manufacturer to wirelessly stream music, phone calls, TV shows, and endless other media to a compatible Phonak hearing aid and a Naída CI sound processor at the same time.

Phonak UltraZoom Feature

Speech understanding in noise—this dual-microphone technology pioneered by Phonak is designed to focus on sound from a speaker located in front of the listener for improved speech understanding in noisy settings.


Automatically analyzes and adapts to every listening situation you or your child encounters, then separates speech from surrounding noise for improved understanding and comfortable conversing.

*Not approved for pediatric patients in the United States.


HiRes™ Optima Sound Processing*

Built on HiRes Fidelity 120 technology, this all-new strategy is designed for optimized performance with better battery life.


*Not approved for pediatric patients in the United States.

HiRes Fidelity 120™ *

Designed to deliver five times more spectral resolution (120 spectral bands) than competing processing strategies, so you hear more of the detail in speech, music, and life.

*Not approved for pediatric patients in the United States.


Adapts dynamically to every environment, automatically adjusting volume levels to optimize hearing, so you can concentrate on listening instead of making adjustments to your sound processor.

Wide Input Dynamic Range (IDR)

Designed to enable you or your child to better hear soft speech, speech in noise, and the details of music.

Deb’s Success with ClearVoice

“ClearVoice has been the best thing since getting the implant. I didn’t think it was possible to actually improve on it that much. The improvement was immediate and significant.”

Deb Lenihan, implanted at age 36

Enjoy Music More with AB

“Current steering (HiRes Fidelity 120*)...represents arguably the most exciting development in sound processing strategies since the introduction of the multichannel implant...the ability to perceive music is being increasingly viewed as a pinnacle of achievement that may be possible through cochlear implants.”

Charles J. Limb, MD; Associate Professor, Department of Otolaryngology, Johns Hopkins Hospital; from Current Opinion in Otolaryngology-Head and Neck Surgery, 14:337–340, 2006.8

What is IDR?

Input Dynamic Range (IDR) is the range of the softest to loudest sounds that are detected by a sound processor. The wider the range, the more sounds you hear. AB’s AutoSound technology captures and delivers the widest range of sound of any cochlear implant system. With this wide range, you hear closest to the way normal-hearing people do, from a whisper to a shout.

Hear Your Best in Everyday Situations

This independent study shows that AB outperforms the competition in three common hearing situations: quiet environments such as libraries, noisy settings such as restaurants, and soft speech such as a whisper.2

The high spectral resolution of the Harmony system helps you hear in real-world settings. And unlike competitor devices, with AB AutoSound technology, there’s no need to fumble with dials, switches, or remote controls every time you move from quiet to loud listening environments.

School-age kids naturally have a hard enough time focusing in a classroom without the additional distraction of needing to make continual adjustments to their sound processor. Your child’s teachers don’t need to worry that important lessons aren’t being heard when your child is hearing with AutoSound.

Hear Your Best in Noise

Whether you’re in a meeting at the office or your child is listening to the teacher in a boisterous classroom, hearing speech is crucial to fully participate. This independent study proves that AB recipients hear speech better in noisy situations and group gatherings.3 AB’s unique AutoSound technology automatically adapts to challenging listening environments so that you hear your best in every situation.

Children begin learning to speak from the day they’re born. By age 3, they need to hear approximately 30,000 words a day to develop language skills necessary to succeed in school.4 For something as critical as the ability to hear, you don’t want to compromise performance.You want your child to have the most technologically advanced, best performing cochlear implant available.

Hear Your Best while Listening to Soft Speech

This study demonstrates that the Harmony sound processor’s wide Input Dynamic Range (IDR) makes it easier to hear in the real world. Harmony users understand soft speech much better with a wide IDR than a narrow IDR. They’re also able to hear sounds that alert you - such as telephone rings, car horns, doorbells, and alarm clocks - much better with the Harmony processor’s wide IDR.5 In the same study, Harmony recipients preferred a wide IDR over a narrow IDR for listening to music.5 The competition provides a narrower IDR than AB does.

Hear Your Best for Speech Development

This independent study shows that during the initial six months of implant use, children with AB devices outperform children with competitor devices in developing both the listening and speaking abilities needed to succeed in life.6

That means you can expect to hear “I love you, Mommy” sooner when you choose AB for your child instead of the competition. As your child grows with AB, they’ll have an opportunity to hear their best during those critical years of language development right alongside their normal-hearing classmates in a mainstream school setting.

Hear Your Best while Listening to Music

This important study proves that Harmony users have the opportunity to hear and enjoy music better than ever before.7,8 HiRes Fidelity 120 sound processing is the only strategy that can implement simultaneous current steering to deliver the dimensions of music (loudness, pitch, timing) for a full musical experience. AutoSound’s programmable wide Input Dynamic Range (IDR) and automatic volume control adjust automatically so that you don’t miss a note. And the naturally placed T-Mic Microphone makes it effortless to use your MP3 player.

This advanced technology only from AB works in concert so that you can hear your best.

What is Current Steering?

Current steering is the process of using multiple current sources to stimulate two electrodes at the same time so that recipients hear additional pitches compared to when either electrode is stimulated alone. The industry’s innovation leader, AB offers HiRes Fidelity 120, a breakthrough in sound processing technology that uses current steering to increase the number of pitches heard. Studies have shown that compared to using other sound processing strategies, AB recipients using HiRes Fidelity 120 hear speech better in noise, and they experience improvements in music and sound quality.10-12
