Choosing between cochlear implants and hearing aids
Approximately 12 million Americans wear hearing aids, while only about 50,000 Americans have cochlear implants. If you or your child has severe to profound hearing loss, cochlear implant surgery might be a good option. If your hearing loss is not severe, then a hearing aid may be the right choice for you.
The difference between cochlear implants and hearing aids
Although cochlear implants and hearing aids might seem to do similar things at first glance, they are two very different instruments. Hearing aids are removable devices while cochlear implants require surgery. A hearing aid magnifies certain sounds and reduces ambient noise and other unwanted sounds. A cochlear implant is surgically implanted and sends electrical impulses through the auditory nerve. The brain recognizes these impulses as sound. While a hearing aid can totally or nearly restore hearing, a cochlear implant can only simulate hearing. A hearing aid works best when fitted by an audiologist. A cochlear implant requires surgery and therapy afterward to learn how to use it and understand how it works.
|Cochlear Implants||Hearing Aids|
|Can cost up to $100,000||Typically cost between $1,000—$4,000 each|
|Require care when performing sports, especially water sports and contact sports||Can be worn during most sports, though some care is required|
|Waterproof versions are available; otherwise, the outer portion must be removed before going in water||Available as waterproof, or waterproof covers can be used|
|Using one is different from traditional hearing and requires therapy to learn or relearn hearing||Works for those with mild to moderate hearing loss|
|Side effects include dizziness, paralysis and additional loss of any hearing||Not permanent and can be removed if causing irritation or discomfort|
|Cochlear implants can affect MRI scans||Removable for medical procedures|
Cochlear implants are small electronic devices that provide sound to people with significant or profound hearing loss. Like hearing aids, cochlear implants can help you hear better. The main difference is they are surgically implanted under the skin behind the ear instead of being removable. The implants do not restore hearing; instead, they directly stimulate the auditory nerve, which can help the wearer better understand speech. A cochlear implant might be the right option for children or adults who cannot be helped by hearing aids.
A cochlear implant works as a prosthetic for the damaged portions of the inner ear. The implant consists of two parts: an outer section with a microphone and processor, and an internal element that transmits electric pulses to the auditory nerve. A cochlear implant receives sounds through the outer component, processes the information and sends it to the internal element, which transmits data as electric pulses to the brain.
Cochlear implant pros and cons
Benefits of cochlear implants
Cochlear implants can be life-changing and come with several benefits. They make communication and social interaction with peers easier. A person may be able to listen to music. For babies and children, cochlear implants are less likely to be pulled out and lost. Medicare and most insurance plans cover cochlear implants.
Disadvantages of cochlear implants
Cochlear implants may also have negative effects. They require surgery, which is a strong consideration for medically fragile individuals. The price for the implantation surgery alone can run up to $50,000, and initial consultations and follow-up therapies can cost an additional $30,000 to $50,000.
Cochlear implant risks
The surgery for cochlear implants involves anesthesia, which always carries some risks. If the device doesn’t work or needs to be repaired, additional surgery might be required. In addition, the recipient will have to avoid getting the cochlear implant wet. This can damage the implant, requiring expensive repairs.
Hearing aids are small devices worn in or around the ear that help users hear better. In the past, most hearing aids were analog, but today most are digital. They are equipped with complex technology that allows wearers to customize their hearing experience. The hearing aid market today is vast and rapidly increasing in technological ability. Hearing aids come in a wide range of prices.
Traditional analog hearing aids turn sound waves into electrical signals. These signals, in turn, are amplified. Digital hearing aids are highly advanced pieces of technology that convert sound waves into numerical codes. These numerical codes contain information about the sound’s pitch and volume. The hearing aid uses this information to amplify certain frequencies and diminish others. This all happens in an instant. The digital nature of these types of hearing aids allows for a highly customizable experience.
Hearing aid pros and cons
Benefits of hearing aids
Hearing aids cost less than cochlear implants. For a cost that breaks down to just a few dollars a day, hearing aids allow people to hear the sounds of the world around them. This can help them at work, in social settings and at play. Hearing aids can help relieve symptoms of tinnitus, or ringing in the ears. For most hearing aid users, the price is well worth the ability to better hear music, the sounds of nature and their loved ones. The intangible benefits of hearing aids are difficult to overstate.
Disadvantages of hearing aids
Hearing aids that deliver a truly customizable, quality experience are expensive. A common problem with hearing aids is unwanted feedback, either from the wind or from other noises, though experts are working hard on technologies that reduce this feedback, and many hearing aids today have features that do reduce feedback. Another disadvantage of hearing aids is that they need to be refitted from time to time because of changes in the user's body. Some hearing aids, depending on the model, also need to be cleaned frequently.
