What is a cochlear implant?
A cochlear implant is an electronic device, which can enhance hearing and speech abilities for individuals with severe to profound hearing loss. A cochlear implant system comes in two parts; the first part is the external speech processor and the second is the internal implant which is placed under the skin.

What should I consider when choosing my cochlear implant?
When considering which cochlear implant manufacturer is most suited for you, you may want to compare product features, design, ease of use, performance and, most importantly, long term reliability of the device. Reputable implant manufacturers produce reports on the results of their devices. Be sure to ask your Cochlear Implant Consultant for copies of such reports contact Cochlear’s UK office via email on info@cochlear.co.uk or phone 0208 8794900 and ask for our latest reliability report.
How does Cochlear compare in reliabiliy to other manufacturers?
Cochlear is known in the industry for developing the most advanced and reliable cochlear implants. It's built using the toughest materials available and tested to the highest military/space grade standards.
How will I hear after I have my cochlear implant?
Everyone’s initial experience with their cochlear implant is unique. However, most implant users say that the sound changes with time and gets better every day. If you’ve previously used a hearing aid you’ll notice a difference in sound with your new implant. You may notice a more ‘tinny’ sound quality at the beginning, as you’ll be able to hear high pitch sounds that you might not have heard for a long time.
Children who’ve had little or no hearing prior to their cochlear implant appear to get used to the sound very quickly.
If you are uncomfortable with the sounds you experience after switch-on, work with your Cochlear Implant Consultant or Audiologist until the sound is improved.
Should I wait for the newest technology?
At Cochlear, we design our products so that you can benefit from new technological innovations without the need for additional surgery. Our track record demonstrates this. Nucleus users implanted 20 years ago now have the same access to features available to users implanted just recently. In addition, we gave Nucleus Freedom the processing power and programming flexibility to handle technology advancements that aren’t even available today.
What is the most technically advanced cochlear implant available today?
Nucleus® Freedom™ is Cochlear’s most technically advanced cochlear implant system available. It is the world’s first sweat and splash-resistant cochlear implant system and the only system on the market with SmartSound™. SmartSound is a revolutionary new technology that is designed to enable better hearing in more everyday situations. It’s designed to behave much in the same way as natural hearing, letting you focus on and hear the sounds that are most important.
When will I have surgery and what can I expect?
Your operation will be arranged after your consulting clinic has completed all your evaluations. Ask your Cochlear Implant Consultant for more information about your surgery.
Cochlear implant surgery normally takes 1-3 hours. Typically, you would go home later the same day or early the following morning. Most people return to normal activities within a few days or a week. As with any operation there may be an element of discomfort. Most discomfort or pain after the operation can be managed with normal pain-killers.
The external processor is typically activated within 4-6 weeks after surgery.
Will I get one or two implants?
Currently in the UK and Ireland the majority of patients receiving a cochlear implant receive only one; however there are a few specific cases in which a patient may receive two implants. In these instances a strong medical case may be presented by the medical team such in cases of Meningitis.
What does the outside part of the cochlear implant look like?
A cochlear implant has two parts: an internal part, called the cochlear implant and an external part called a speech processor. You cannot see the internal part because it is under the skin. There are two types of speech processors:
1) The behind-the-ear models like the Nucleus Freedom BTE, which sits behind the ear similar to a hearing aid.
2) The Nucleus Freedom Bodyworn is about the size of an iPod Shuffle and can be worn at the waist or in a small pocket. A thin cable connects the microphone to the processor. This type of speech processor is ideal for infants, young children or older adults that want easy direct access to the control panel.
Do I have to limit my sports activity? What about SCUBA diving and swimming?
Having a cochlear implant will not limit your swimming or sports activity. For swimming you will need to remove the external component when you swim, much like you would have to remove a hearing aid. The internal part of the cochlear implant is not affected by water. More aggressive or contact sports require you to wear a helmet to protect your equipment. Boxing and other aggressive sports are discouraged.
For SCUBA divers, the internal implant is validated to withstand pressure at a depth of 25 meters (82 feet) underwater. However, it is recommended that you check with your surgeon or clinician before participating in a dive. There may be other medical conditions that you will need to consider.
How long do the batteries in the processors last?
Batteries for the behind-the-ear model of speech processor typically last several days, whilst the rechargeable batteries used in bodyworn processor normally last for one day.
Generally if you are in noisy environments your speech processor works harder and therefore requires more battery power.
What type of batteries do the processors take?
Behind-the-ear processors use small high-powered zinc-air style batteries similar to those used in hearing aids, whilst body worn processors normally use rechargeable or standard AA or AAA batteries depending on the model. Your Cochlear Implant Consultant will be able to suggest the best battery type for your processor.
What is a ‘Microlink’?
A ‘Microlink’ is a miniaturised Radio Aid (FM) system for hearing aid and cochlear implant users. The Microlink state-of-the-art receiver attaches directly to the speech processor, enhancing speech understanding, particularly in difficult hearing situations. This tiny receiver is compatible with Phonak’s range of transmitters as well as those produced by other manufacturers. For more information refer to Phonak’s website.
Children wishing to take advantage of Mircolink technology can get funding via local education services, whilst adults can seek funding through a variety of different charitable and professional bodies.
Please contact your Cochlear Implant Consultant for more information.
Who invented cochlear implants?
Professor Graeme Clark of the University of Melbourne was the creator and developer of the world’s first multi-channel implant and is considered by many to be the father of the cochlear implant. Professor Clark continues to work closely with Cochlear to bring the gift of hearing to every child and adult who can benefit.
