Completely-In-The-Canal (CIC)
The CIC aid fits completely within the ear canal and is the least visible of all the
hearing aid styles.
Advantages:
1. It fits a wide range of hearing losses.
2. It is virtually invisible and therefore the most cosmetically appealing instrument.
3. It is the best choice in hearing aids for telephone use because it has the least chance of feedback.
4. The microphone is located in a more natural sound-gathering position (at or slightly inside the ear canal opening) which allows the outer ear to provide more high-frequency emphasis and enhanced localization.
5. It requires less overall power because of the close proximity of the receiver to the eardrum.
Disadvantages:
1. It has a somewhat shorter battery life (5-7 days).
2. The smaller battery size may make battery changes difficult if manual dexterity is limited.
3. Ear wax within the hearing aid can frequently plug the receiver.
4. It may cost more than other styles.
5. Patients may experience more occlusion, a sensation of "talking in a barrel", or hearing their own voice as unusually loud.
Most Suitable For People Who:
1. Desire a smaller and more discreet instrument .
2. Use the telephone often and need amplification for telephone conversation.
3. Want to maximize the outer ear’s sound gathering and localization.
