Hearing Aid Styles
Styles of hearing aids include:
Completely-in-the-canal style hearing aids (CIC): these are the smallest and most cosmetically discreet. The CIC instruments fit completely in the canal and are custom-made. There is a clear nylon string to help with insertion and removal. They are powered with a #10 hearing aid battery.
In-the-Canal style hearing aids (ITC): these are larger than the CIC devices. They fit within the ear canal and are custom-made. They are powered with a #312 or #10 hearing aid battery.
In-the-Ear style hearing aids (ITE): these are larger than the ITC style. They fit in the ear, filling the entire “bowl” of the ear. They are custom made. The customization along with the lightweight and compact size makes these instruments comfortable and easy to manage. They are powered by a #13 or #312 battery.
Conventional Behind-the-Ear style hearing aids (BTE): the processing components are housed in a case that fits behind the ear. Sounds enter the instrument, are amplified, and travel through a tube that is contoured over the top of the listener’s ear and into an earmold inside the ear. BTEs are durable, easy to handle and maintain, and can be easily adapted for use with the wide variety of assistive listening devices. They are powered with a #675 or #13 battery.
Open-Fit and Receiver In the Canal Behind the Ear Style: These are similar to the conventional BTE but are much smaller, making them more discreet. A very small tube leads to the ear canal making this option much more cosmetically appealing while offering superior sound quality.

Are there different styles of hearing aids?
There are three basic styles of hearing aids. The styles differ by size, their placement on or inside the ear, and the degree to which they amplify sound.
Behind-the-ear (BTE and RIC) hearing aids
Behind-the-ear (BTE and RIC) hearing aids consist of a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss.
The RIC aid is a new type of open-fit hearing aid. Small, open-fit aids fit behind the ear completely, with only a narrow tube inserted into the ear canal, enabling the canal to remain open. For this reason, open-fit hearing aids may be a good choice for people who experience a buildup of earwax, since this type of aid is less likely to be damaged by such substances. In addition, some people may prefer the open-fit hearing aid because their perception of their voice does not sound “plugged up.”
BTE – Behind the ear
RIC – Reciever in the canal
In-the-ear (ITE and ITC) hearing aids
In-the-ear (ITE and ITC) hearing aids fit completely inside the outer ear and are used for mild to severe hearing loss. The case holding the electronic components is made of hard plastic. Some ITE aids may have certain added features installed, such as a telecoil. A telecoil is a small magnetic coil that allows users to receive sound through the circuitry of the hearing aid, rather than through its microphone. This makes it easier to hear conversations over the telephone. A telecoil also helps people hear in public facilities that have installed special sound systems, called induction loop systems. Induction loop systems can be found in many churches, schools, airports, and auditoriums. ITE and ITC aids usually are not worn by young children because the casings need to be replaced often as the ear grows.
ITE – In the ear
ITC – In the canal
Canal hearing aids
Canal aids fit into the ear canal and are available in two styles. The completely-in-canal (CIC) hearing aid is nearly hidden in the ear canal. The Invisible In the Canal (IIC) is the smallest style and is completely invisible. Both types are used for mild to moderately severe hearing loss.
Because they are small, canal aids may be difficult for a person to adjust and remove. In addition, canal aids have less space available for batteries and additional devices, such as a telecoil. They usually are not recommended for young children or for people with severe to profound hearing loss because their reduced size limits their power and volume.
CIC- Completely in the canal
IIC – Invisible in the canal
