Did you know that Cochlear implant procedures have been performed for over 40 years? Since 1977, over 550,000 Cochlear hearing devices have been implanted worldwide. It is estimated that more than 15 million people around the globe could potentially benefit from a Cochlear implant. But Cochlear implants are just one type of hearing implant. There are, in fact, many others, including devices from brands like Med-el and Advanced Bionics.
This article will discuss the different types of hearing implants before looking at the Cochlear implant providers commonly available and approved for use in Australia.
Firstly, a reminder to read our introductory post on Cochlear implants to find out what they are and how they work – if you haven’t already.
Hearing implants are compact electronic devices that are surgically implanted into the ear. Hearing implants can provide a range of benefits to a person with moderate to severe hearing loss.
The most common types of hearing implants include:
Bone conduction implant (Med-el’s “Bonebridge”)
Middle ear implant (Med-el’s “Vibrant Soundbridge”)
A Cochlear implant is a small electronic device that helps those with moderate to severe hearing loss. Although Cochlear implants cannot restore normal hearing; they can restore some hearing capabilities in people who have severe to profound hearing loss. Cochlear implants are a fantastic technology that allows those with little to no hearing to experience sounds again and improve their day to day communication with friends and family.
In Cochlear implants, an external speech processor captures the sound and converts it into digital signals. Those signals are passed on to an internal implant that is inserted in the middle ear. There, the signals are converted into electrical energy and passed on to the Cochlear to stimulate the hearing nerve whilst bypassing damaged hair cells.
There are three major global manufacturers of Cochlear implants that supply the Australian market: Cochlear, Med-el and Advanced Bionics. Within the three manufacturers, there are various brands and types of hearing implants, which can be confusing.
Your Implant Audiologist can help you navigate these options and assist with decision making based on:
You may be able to choose which brand and device you want, depending on whether you participate in a private or public Cochlear implant program. The latter may only have one brand available.
Reviewing different products can be super confusing. Many Cochlear implants have more than 60 features and there are many general differences between the three brands. This task is made more accessible by the Cochlear Implant Comparison Chart, created by Tom Hannon and Howard Samuels, both bilateral Advanced Bionics recipients.
The brand comparison chart below has been reduced for ease of reference. It is to be used as a guide only. The revised brand comparative chart highlights the different types of cochlear implants available in the Australian market.

Industry experts, including experienced Implant Audiologists, will tell you there’s little difference between the three brands listed concerning sound processing. The comparison chart between the brands shows that other factors will influence which brand to choose from a patient, surgical, and audiological view.
Your surgeon will always choose the internal implant device from whichever brand has been selected, given factors such as your Cochlea anatomy and whether hearing preservation is required. With input from your Implant Audiologist, you will make the final decision about which brand external sound processor device you prefer (unless you are in an implant program that chooses for you).
Three major global Cochlear implant manufacturers supply their hearing implants to Australians with severe to profound hearing loss. All have excellent quality assured mechanisms in place and are well versed in producing and providing world-class implant devices.
Your Implant Audiologist and Implant Surgeon will discuss your options with you and assist in making the right decision. If you are not part of a hearing implant program, you will have several options to choose from.
All brands have standard options and accessories; others may have to be purchased separately. You will need to check the ‘What’s in the kit’ pages of each brand and discuss those with the Implant Audiologist. Your Implant Audiologist can show you all the models available and allow you to handle them, look at sizes and shapes, see the wireless options and other accessories, and learn about their features.
Ultimately, you can rest assured that you will receive a quality product from major brands, approved by the Therapeutic Goods Administration (TGA) to provide their Cochlear implant types in Australia.
