Many types of hearing aids exist. So which is best for you? Find out what to consider when choosing a hearing aid.
By Mayo Clinic staff
Knowing more about the hearing aid options available to you, what to look for when buying a hearing aid and how to break it in may help alleviate some of your concerns.

Completely in the canal
Completely-in-the-canal hearing aids are molded to fit inside your ear canal and can improve mild to moderate hearing loss in adults.

A completely-in-the-canal hearing aid:

* Is the least noticeable in the ear
* Is less likely to pick up wind noise because the ear protects the instrument
* Is easy to use with the telephone
* Uses smaller batteries, which typically don’t last as long as larger batteries
* Doesn’t contain extra features, such as volume control or directional microphones

In the canal
An in-the-canal hearing aid is custom molded and fits partly in the ear canal, but not as deeply as the completely-in-the-canal aid. This hearing aid can improve mild to moderate hearing loss in adults.

An in-the-canal hearing aid:

* Is less visible in the ear
* Is easy to use with the telephone
* Includes features that won’t fit on completely-in-the-canal aids, but the small size can make the features difficult to adjust
* May not fit well in smaller ears

Half-shell
A smaller version of the in-the-canal hearing aid, the half-shell is custom molded and fills the lower portion of the bowl-shaped area of your outer ear. This style is appropriate for mild to moderately severe hearing loss.

A half-shell hearing aid:

* Is bigger than an in-the-canal hearing aid
* Is a little easier to handle than are the smaller hearing aids
* Includes additional features, such as directional microphones and volume control
* Fits most ears

In the ear (full shell)
An in-the-ear (full-shell) hearing aid is custom made and fills most of the bowl-shaped area of your outer ear. This style is helpful for people with mild to severe hearing loss.

An in-the-ear hearing aid:

* Is more visible to others
* May pick up wind noise
* Contains helpful features, such as volume control, that are easier to adjust
* Is generally easier to insert into the ear
* Uses larger batteries, which typically last longer and are easier to handle

Behind the ear
Behind-the-ear hearing aids hook over the top of your ear and rest behind the ear. The hearing aid picks up sound, amplifies it and carries the amplified sound to an ear mold that fits inside your ear canal. This type of aid is appropriate for almost all types of hearing loss and for people of all ages.

A behind-the-ear aid:

* Is the largest, most visible type of hearing aid, though some new versions are smaller, streamlined and barely visible
* Is capable of more amplification than are other hearing aid styles

Open fit
These are very small behind-the-ear-style devices. Sound travels from the instrument through a small tube or wire to a tiny dome or speaker in the ear canal. These aids leave the ear canal open, so they are best for mild to moderate high-frequency losses where low-frequency hearing is still normal or near normal.

An open-fit hearing aid:

* Is less visible
* Doesn’t plug the ear like the small in-the-canal hearing aids do
* Uses very small batteries
* Lacks manual adjustments due to the small size

Hearing aid electronics

Hearing aid electronics control how sound is transferred from the environment to your inner ear. All hearing aids amplify sounds, making them louder so that you can hear them better. Most hearing aid manufacturers now only produce digital hearing aids — analog hearing aids are being phased out.

With digital technology, a computer chip converts the incoming sound into digital code, then analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. The signals are then converted back into sound waves and delivered to your ears. The result is sound that’s more finely tuned to your hearing loss. Digital hearing aids are available in all styles and price ranges.

Hearing aid options
Some hearing aid options improve your ability to hear in specific situations:
* Directional microphones *Telephone adapters. * Bluetooth technology.* Remote controls

Before the purchase: Steps to take
When looking for a hearing aid, explore your options to understand what type of hearing aid will work best for you. Also:
# Seek a referral to a reputable audiologist. If you don’t know one, ask your doctor for a referral. A good audiologist works with you to find a hearing aid that best fits your needs and desires. This person takes an impression of your ear canal, chooses the most appropriate aid and adjusts the device to fit well. Be cautious of free consultations and people who sell only one brand of hearing aid.
# Ask about a trial
