There are four main categories of hearing instruments:
Completely-in-the-canal (CIC)
Completely-in-the-canal (CIC) are custom made so that all components fit inside the shell, but they are worn deeper in the ear canal than in-the-ear hearing aids (ITE's) which are described in the following category and are almost invisible. Less amplification is required from CIC than other types of hearing instruments because output is delivered close to the eardrum. ClC reduces the awareness wearers have of their own voice and their ears do not feel as "plugged up" as with other types of instruments. The technical term for this benefit is "reduced occlusion effect". Wind-noise and telephones pose fewer problems to wearers of CIC compared to the other types of instruments as well.
--------------------------------------------------------------------------------
In-the-ear (ITE)
In-the ear hearing aids (ITE) became available in the late 1970's and are now the most popular style of hearing instrument in North America. Consumers are attracted to the discreet styling of ITE which come in several sizes including full shell (large) to half shell (small). All the instruments electrical components are housed within the custom-made shell which is worn inserted in the ear. These devices use smaller batteries than BTE and may have a shorter battery-life, but the microphone is located in a more natural position on ITE than on BTE and some people find that this provides better sound quality.
--------------------------------------------------------------------------------
In-the-Canal (ITC)
In-the-canal (ITC) hearing aids are smaller and are custom made to fit the shape of your ear canal. These aids can be worn during most physical activity. They also fit more deeply than in-the-ear hearing aids and therefore are popular because of their cosmetic appeal. All of the components within the single plastic shell fit into the ear.
--------------------------------------------------------------------------------
Behind-the-ear (BTE)
Behind-the ear (BTE) were the most common hearing instruments in North America from the 1950's-1970's, and they continue to outsell all other hearing instruments world-wide. BTE aids are reliable and offer fitting flexibility in addition to power. These instruments sit behind the ear and amplify incoming sound. The amplified sound travels down a short tube connected to a custom-fitted earmold that delivers the sound into the ear canal, towards the eardrum.
--------------------------------------------------------------------------------
Not all clients are good candidates for CIC's. People who should not wear this type of instrument:
produce excess amounts of earwax
have extremely curvy, small or straight ear canals
have hearing losses of over 80 dB
have poor manual dexterity
are unable to afford a lot of money for hearing instruments or batteries.
