Hi everyone: this is just a brief note about the differences in Hearing Aids styles just in case some of you have to go out to the market to get a pair for yourself or a relative.
All hearing aids contain the same parts to carry sound from the environment into your ear. However, hearing aids do come in a number of styles, which differ in size and the way they're placed in your ear. Some are small enough to fit inside your ear canal, making them almost invisible. Others fit partially in your ear.
canal.
The following are common hearing aid styles.
1) 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.
2) 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.
3) 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.
4) 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
5) 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
6) Open fit
These are usually very small behind-the-ear-style devices, although larger behind-the-ear devices can be modified for a more "open" fit. 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're best for mild to moderate high-frequency losses where low-frequency hearing is still normal or near normal.
Have a great day!
