Cochlear implants vs. hearing aids
Which option is best for you?
Approximately 12 million Americans wear hearing aids, while just over 180,000 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.
Hearing aids amplify sound and filter background noise, while cochlear implants bypass damaged parts of the ear to send electrical signals directly to the auditory nerve.
Jump to insightModern digital hearing aids provide a highly customizable listening experience by amplifying specific frequencies based on the wearer’s needs. They are generally more affordable than cochlear implants and do not require surgery.

Jump to insightThe 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
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
Pros
- Make communication and social interaction with peers easier
- May allow user to listen to music
- Less likely to be pulled out and lost by babies and children that need them
- Medicare and most insurance plans cover them
Cons
- Require surgery
- Expensive implantation surgery (up to $50,000) and consultations and follow-up therapies (additional $30,000 to $50,000)
- Additional surgery may be required if device doesn’t work or needs repairs
- Can’t get the cochlear implant wet
Hearing aids
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
Pros
- More affordable than cochlear implants
- Can help relieve symptoms of tinnitus

Bottom line: Cochlear implant or hearing aid?
Cochlear implants are best for those with severe to profound hearing loss. Cochlear implants are very expensive, but they provide the possibility of experiencing sound when before it was impossible. This can completely change a loved one's life.
Hearing aids are best for those who have mild to moderate hearing loss. If you think that your life could be improved by being better able to hear the sounds around you, consider purchasing a hearing aid. Once you have chosen a hearing aid, an experienced audiologist will help you fit it.
