Kids Hear Their Best with Surround Sound

Whether your child already has one cochlear implant or you’re considering cochlear implants for the first time, using cochlear implants in both ears (bilateral implantation) may provide the best possible hearing.1

Two cochlear implants provide: 2,3

  • Better hearing in challenging environments, making it easier to hear on playgrounds
  • Improved ability to localise sound, making it easier to know the direction of an alarm, car horn, etc.
  • Greater ease of listening, making it less exhausting to keep up with conversations
  • Enhanced sound quality, making it easier to fully appreciate music and more

Rosie's Bilateral Journey to Hearing

“The huge difference we noticed was Rosie’s ability to listen in noisy environments. Even though we were riding in a van, me facing forward driving, with a noisy baby sister chatting next to her, a DVD playing on a screen and through the speakers, Rosie was still able to answer my questions easily – it was amazing!”

— Natasha McDougald, mother of Rosie, implanted by age 12 months, bilaterally implanted at age 2

Two Ears are Naturally Better than One

Natural hearing is called binaural hearing – “bi” for two, “aural” for ears. Two ears work together to gather the full sphere of sound and deliver it to the brain where it’s almost instantly processed, giving the listener the ability to respond quickly and appropriately. Bilateral implantation merges sound from two ears so that your child’s hearing is better than with one implant alone.

Two cochlear implants merge sound from two ears, giving severe-to-profoundly deaf children the opportunity to hear their world in surround sound, too. 

Children Who Hear More Advance More

Binaural hearing is the optimal choice for your child’s speech, language, and communication development. Stimulating the hearing nerves in both ears early in a child’s life may improve their ability to listen, talk, and learn along with their normal-hearing peers.

Literature on cochlear implants makes it clear that bilateral children – as well as adults – perform better with two cochlear implants than with one.4


Bilateral Benefits for Every Stage of Life

While the ability to develop language skills is strongest at a young age, older children who have depended on one implant for several years can still experience many benefits of bilateral implantation with a second one. 


Jake Succeeds with Two Implants

“I began thinking about him going bilateral once he began benefitting from the first implant. The day Jake’s second implant was switched on, he didn’t want to take the Harmony processor off because it helped with background noise. Going bilateral is the best thing we’ve ever done, apart from having the first one.”

— Jane Foreman, mother of Jake, implanted at age 5, bilaterally implanted at age 13

Hear More with a Second Implant

If your child has one “good ear” with their first cochlear implant, consider the profound benefits a second implant can bring. Hearing with two cochlear implants can give your child a richer, more dimensional sound and improved ability to hear softer sounds.2,3

Children with two cochlear implants may:

  • Hear better in noisy environments like the classroom and playground. This allows them to focus on the important things like school – or play!
  • Develop speech more naturally. Bilateral cochlear implants deliver surround sound to your child’s brain during critical periods for speech and language development.
  • Localise sound sources more easily. They are better able to determine the location of a sound, like a friend’s “hello” or a fire alarm, and turn to it – giving them more confidence in social situations – and giving you greater peace of mind.
  • Listen with less effort. Less strain means your child can concentrate on learning.
  • Sit anywhere to hear their best. When both ears work well, they don’t have to think about positioning themselves so their “good” ear can hear.

Research Reinforces Bilateral Benefits

Clinical research proves that bilateral implantation will benefit your child in their current day-to-day activities as well as in the future when they become adults and begin contributing at work, attending networking events, socialising with friends, or caring for children of their own.


Hear in Challenging Listening Situations

Two cochlear implants help adults interact with friends and business associates at noisy restaurants, parties or even during meetings. Adults who use two cochlear implant hear much better in noise compared to those with just one.

Percent of adults showing better scores with two implants compared to one implant for three tests of listening to speech in noise of varying difficulties.1


Improve Speech Discrimination

Adult recipients can discriminate speech better with two implants compared to listening with one implant alone – even in quiet settings. From romantic dinners to conferences, bilaterally implanted adults recognise more spoken words.

Average word scores in quiet 3, 6, and 8 months after implantation for 15 adults implanted in both ears at the same time. Understanding speech is easier with two implants, and improves with experience.1


Localise Sound with Accuracy and Ease

From ambulance sirens to beeping car horns, adults with two cochlear implants can tell where sounds come from more accurately compared to using one implant alone, more like their normal-hearing peers.

Left vs. right localisation accuracy for the right implant alone, left implant alone, and both implants together. Localisation is improved significantly when using two implants.1


Frequently Asked Questions

AB has provided a list of common questions. However, if you have a question you don’t see answered here, contact Advanced Bionics.

1.  Are the candidacy guidelines different for bilateral cochlear implant recipients?
  No, the guidelines are the same whether consideration is for one or two cochlear implants. To see if your child may be a candidate, take the online quiz. 

 

Is your Child a Candidate for Cochlear Implants?

Take our child candidacy quiz (check all that apply):

  My child has delayed speech and language development as a result of his or her hearing loss.
   
  My child child rarely responds to his or her name.
   
  My child avoids social interaction or lacks the appropriate skills to interact with other children or adults.
   
  I have concerns about my child's ability to hear speech in noisy environments.

If you checked one or more of the above, then your child may be a candidate for Cochlear implants.

2. Can my child hear well with two different processors?
  It is common for an individual to wait a year or more between their first and second (bilateral) cochlear implant. The ears collect and deliver sound to the brain. Therefore, a different cochlear implant system in each ear can work very well because the system is programmed for the unique hearing needs of each ear.
   
3. Can the brain bring the two sounds together, even if it’s been a long time since my child received their first implant?
  There is no reason to wait on choosing bilateral hearing. In children, the sooner they have access to sound, the better the outcome. For older children, teens, and adults, experience with the second implant is key for the best hearing experience possible.3 Many individuals new to bilateral listening can notice an immediate benefit – which improves over time – including clearer speech, ease of listening, a more natural sound quality, and a new appreciation for music.
   
4. What would the advantage of going bilateral be for my child now as they hear very well and test normally with the first implant?
  Testing normally in the clinic and hearing well in the real world are not the same. An implant in one ear cannot compensate for hearing with two ears. Remember that hearing with two ears provides many advantages – localising the source of sound, hearing more clearly in noise, and enjoying a richer experience with music.
   
5. My child still has residual hearing in their non-implant ear, is it better to have a hearing aid in this ear than another cochlear implant?
  Residual hearing doesn’t mean useable hearing, even with a hearing aid. The best way to know if an ear may benefit from a cochlear implant is to be evaluated by an audiologist. If you are unsure of whether or not you might be a candidate for bilateral cochlear implants, contact your hearing healthcare professional.
6. Will the implantation be quicker than for my child's first implant?
  The implantation experience is unique to each individual. Like technology, implantation practices can change and improve. Each person considering a cochlear implant should discuss the implantation procedure and expectations with the implantation team and audiolgist.
