Hearing aids and cochlear implants can amplify sounds and make them easier for people to hear. Hearing aids do not need surgery, but cochlear implants do.
This article explores the difference between cochlear implants and hearing aids, what to consider before buying these devices, several products a person might want to consider, and why hearing tests are important.
Hearing aids comprise three parts:
- a microphone, which receives and converts sound waves into electrical signals
- an amplifier, which magnifies the sound
- a speaker, which sends the amplified sound into the person’s ear
Most hearing aids feature different sound profiles suitable for multiple sound environments, such as a quiet room and a busy stadium.
There are multiple styles of hearing aids, including behind-the-ear (BTE), completely-in-canal, and receiver-in-ear. Some of these styles may be more suitable for different degrees of hearing loss.
These devices bypass the inner ear to stimulate the auditory nerve directly, giving a sensation of sound for those with profound hearing loss.
However, cochlear implants are only suitable for those with sensorineural hearing loss. This form of hearing loss results from damage to the hair cells in the inner ear, the brain’s central processing centers, or the vestibulocochlear nerve. Some
Some cochlear implants, such as hybrid models, are suitable for people with residual hearing. These hybrid devices can help preserve hearing for these individuals, with
Cochlear implants feature four main parts: a microphone that picks up sound and sends it to a speech processor, which a transmitter and receiver pick up and convert into electric impulses. An electrode array then collects this information and sends them to the auditory nerve.
One of the largest differences between hearing aids and cochlear implants is that individuals can easily take off their hearing aids, whereas cochlear implants are permanently attached. Most individuals will undergo outpatient surgery to have a cochlear implant. However, children and those with underlying health conditions need inpatient surgery.
Hearing aids are more suitable for those with mild-to-severe hearing loss, whereas cochlear implants are more suited for those with profound hearing loss. While hearing aids amplify sounds, cochlear implants provide a sense of sound. An audiologist can recommend which device is more suitable depending on an individual’s type of hearing loss.
Individuals will need extra support after having a cochlear implant. Speech-language pathologists and audiologists can help people interpret the signals that cochlear implants send.
However, not all health insurance plans cover the costs of hearing aids. Medicaid covers hearing aids for children and young adults
Cochlear implants are not available to purchase online. Individuals can make an appointment with an audiologist or otolaryngologist to determine whether they are eligible for these devices.
Hearing aids and cochlear implants are medical devices — a doctor or audiologist can suggest which product is more suitable for an individual’s requirements.
Once an audiologist has made their recommendation, there are several factors to consider when choosing a hearing aid or cochlear implant.
People purchasing a hearing aid may wish to consider whether the device has:
- different sound profiles and programs
- Bluetooth or wireless compatibility
- rechargeable or nonrechargeable batteries
- compatible hearing aid apps
- warranties, refunds, and guarantees
- a suitable hearing aid style
- digital noise reduction and feedback suppression
- synchronization features if an individual has two hearing aids
- directional microphone systems
If an audiologist recommends a cochlear implant, individuals may wish to consider whether the cochlear implant has:
- upgradable, programmable, and future-proof technology
- water-resistance or waterproof capabilities
- rechargeable or nonrechargeable batteries
- a long expected life span
- warranties and guarantees
- features that are compatible with their lifestyle requirements, such as suitability during sports
- easily available replacement parts
- pre- and post-implantation support
Additionally, cochlear implant users may wish to consider the availability of rehabilitation or support groups and online communities that can advise newer users on how to adapt to the device.
Several brands manufacture hearing aids and cochlear implants. Some hearing aids are available to buy online, and others are only available through an audiologist. Individuals cannot purchase cochlear implants online.
Below is a list of hearing aids suitable for varying levels of hearing loss. It also includes a selection of cochlear implants that an audiologist can recommend to those who need them.

Hearing exams are an important part of protecting hearing health, and individuals should have regular hearing checkups. The
- family and friends say that the person has difficulty hearing
- a person has past exposure to a loud noise
- a person is experiencing changes with their hearing
Loud noises can cause hearing loss. The following signs and symptoms may indicate hearing loss from noise exposure:
- tinnitus, a ringing in the ears
- muffled speech and other sounds
- difficulty understanding conversations over the phone or in noisy places
- asking people to repeat, speak louder, or speak in a slow, clear manner
- sensitivity to sound
The United Kingdom National Health Service (NHS) recommends that people follow these measures to protect their hearing:
- wearing hearing protection if they are around loud noises
- reducing the volume while wearing earphones and headphones
- staying away from loud noises when possible
Both hearing aids and cochlear implants are helpful for people with hearing loss. While hearing aids may be more suitable for those with mild-to-moderate hearing loss, cochlear implants are appropriate for those with profound hearing loss or who are severely hard of hearing.
People should consider their level of hearing loss and lifestyle requirements when purchasing a hearing device. Some hearing aids are available to buy online, and others are only available through an audiologist. Individuals cannot purchase cochlear implants online and need an appointment with an audiologist or otolaryngologist to determine if these devices are suitable for them.
