Experience 3D Hearing with HiRes Fidelity 120

Designed to provide hearing that closely resembles how a normal ear hears, AB’s HiRes Fidelity 120™* sound processing captures and delivers the full dimension of sound for a more complete hearing experience.

Only HiRes Fidelity 120 offers five times more sound resolution than any other cochlear implant system - 120 spectral bands - to help you or your child hear all the colorful details of sound: birds chirping, rain falling, the various layers of music. And with HiRes Fidelity 120, your child has the opportunity to hear all the details necessary to understand speech and develop strong language skills.
*Not approved for pediatric patients in the United States.

The Significance of Spectral Resolution
Just the way a high-definition television delivers a higher-quality visual picture, HiRes Fidelity 120 is designed to deliver a higher-quality sound representation. The higher the spectral resolution, the better a recipient can hear a frequency or “pitch.” High spectral resolution is particularly important for listening in noisy environments as well as hearing and appreciating music. AB’s HiRes Fidelity 120 delivers the highest spectral resolution - 120 spectral bands for five times more than other brands - to help you hear every word of your important meeting or every note of your favorite song.

What is Spectral Resolution?
Spectral resolution refers to how well the cochlear implant delivers frequency, or “pitch” information, to the inner ear through a proper sound intensity. Typically, cochlear implant recipients hear different pitches when different electrodes are stimulated and when the rate of the stimulation varies. The better the spectral resolution, the better you can hear these pitches for better hearing in noise and music enjoyment. Improved spectral resolution is designed to more closely resemble normal hearing.

Simultaneous Stimulation is the Secret
Other implants use a single current source to stimulate only one electrode at a time, limiting the number of potential spectral bands. Only AB’s HiRes Fidelity 120 has multiple current sources, enabling two or more electrodes to be stimulated at the same time. This simultaneous stimulation allows current to be “steered” between electrodes, resulting in 120 spectral bands of sounds, giving you or your child the opportunity to hear more pitches. Recipients using research software have demonstrated the ability to perceive up to 450 pitches.1
