Frequently Asked Questions about CIs for adults   

Cochlear implants may be better than hearing aids for people with significant hearing loss. Unlike hearing aids, which make sounds louder, cochlear implants send sounds directly to your hearing nerve so they can be heard clearly. 


Hearing aids basically make sounds louder, but for people with more hearing loss, this may not be enough to make sounds clearer or easier to understand. Cochlear implants send sound directly to the hearing nerve, where it’s sent on to the brain. 


If you feel that hearing aids are not helping you enough, cochlear implants might work better for you. Take the candidacy quiz and talk to your hearing healthcare professional to decide if cochlear implants may be the right choice to manage your hearing loss. 


Cochlear implants let you hear in a different way from those without hearing loss. A cochlear implant sends tiny electrical signals directly to the hearing nerves and onto the brain to be interpreted as sound. For hundreds of thousands of people around the world, cochlear implants help them carry on conversations, use the phone, and enjoy music. For young children, cochlear implants can help them learn speech and language. 

Cochlear implants are available free of charge on the NHS, if you meet the criteria.


Yes! In fact, hearing with a hearing aid in one ear and a matching cochlear implant in the other ear may help you hear better in noisy places1 and help you know where sounds are coming from. AB offers a variety of solutions that, like your natural ears, work together to maximise your hearing. Talk to your hearing healthcare professional about using matching hearing devices to help you hear your best.

Note: Advanced Bionics cochlear implants are indicated with severe to profound bilateral sensorineural hearing loss (≥ 70 dB HL) and for pediatrics with profound bilateral sensorineural hearing loss (≥ 90 dB HL).


Your hearing care professionals are best able to tell you if cochlear implants will help. It’s important to understand that better hearing through a cochlear implant is a process, not a quick fix. But how fast you hear better depends on three things: (1) the technology used, (2) your hearing structures, and (3) hearing training. We encourage you to speak with people who hear with cochlear implants to learn about their experiences.


They love listening to music on their phone. And then once you get them that connectivity to directly hear music, they love it. 

"I actually have a lot of patients who play musical instruments, and that's been amazing to me. They're in marching bands, they're in symphony orchestras, and things like that. …They love listening to music on their phone. And then once you get them that connectivity to directly hear music, they love it. So, that's been surprising to me because for years, we were told, oh, you really can't listen to music or music isn't good. But I have a lot of patients who, not only enjoy music but actually make music, and are, you know, participating very actively in music. So that's been really exciting."

When you choose a cochlear implant  system from AB, as the technology develops you will be able to use our new sound processors without the need for additional surgeries.

Compared to many other surgeries, cochlear implant surgery is simple and minimally invasive. The surgery itself typically takes two to four hours. Because it’s done with general anesthesia, you will also spend additional time in the preparation and recovery areas.


With new surgical techniques, with robot-assisted techniques and with a good HiRes design that we have today, it's possible to preserve hearing in most of the cases.

"Some of my patients are also afraid that they will lose their residual hearing after the surgery. Of course, this can happen, but it's not so often. With the new surgical techniques, with robot-assisted techniques and with a good HiRes design that we have now today, it's possible to preserve hearing in most of the cases. So, I tell my patients that even though there is a risk, the CI will always improve their life and change their life after the surgery."

– Dr. Yannik Nguyen, ENT Surgeon, Pitié-Salpêtrière University Hospital and The Hearing Institute, Paris France.

Depending on your situation and your surgeon, you may go home the same day or spend the night in the hospital. Adults often return to work or typical daily activities within a few days after CI surgery. Your new CI will be activated, or “switched on,” two to four weeks after the implantation surgery, depending on how well you heal. Then, once it’s activated, you will start to hear through your new cochlear implant.


First, find out if a cochlear implant might help you by taking our candidacy quiz and speaking to a hearing healthcare professional. From there, AB will have specialists who will answer all your questions, support you throughout implantation surgery, recovery, and activation. AB will also connect you with a mentor—someone who already hears with a cochlear implant so you can get their first-hand experience. Even after your CI is activated, our AB specialist will stay with you to make sure you get the most out of your CI with hearing training tools and resources.


Yes, air travel is safe for people with cochlear implants. Metal detectors and security scanners should not damage the implant or sound processor. But, when you go through security metal detectors, your cochlear implant may activate the alarm.  That's why it’s helpful for you to carry your “Patient Emergency Identification Card” with you at all times. 


Yes! AB’s HiRes Ultra 3D Cochlear Implant is safe for up to 3.0 Tesla MRI scans without any preparation, surgery, or head bandaging. Simply take off your headpiece and sound processor before the MRI, and put them back on afterwards.
