Completely-in-canal (CIC) hearing aids are the smallest of all the hearing aid options and different than other possibilities because they are custom fitted to the inside of your ear canal to amplify sounds in people with mild to moderately-severe cases of hearing loss. This style of hearing aid has many advantages, as well as a few disadvantages when compared to other hearing aid styles.
Completely-in-Canals are small and their size and fit hold several aesthetic as well as listening advantages. Because of their small size, it’s difficult for others to notice a CIC without looking for it and it works automatically without extra knobs and buttons to control. They may be more comfortable to wear due to their custom fitting. A few CIC hearing aid models can also be worn for extended periods of time, up to several months in most cases, so you won’t be inconvenienced by having to remember to take out your device when showering or sleeping. Hearing aid models that must be removed daily have a convenient pull-out string that lies inconspicuously outside the ear. It generally doesn’t get in the way of the telephone receiver and, because it is housed inside your ear canal, your outer ear is able to keep out wind noise. Additionally, the natural anatomy of the ear helps guide sound to the instrument, which improves the directionality of the sound.
Because the CIC hearing aids are small, they are generally less powerful and go through batteries faster than larger ones. They are generally the more expensive option because they are custom fitted to the wearer’s ear. Additionally, their tiny size doesn’t leave room for extra features, so you won’t be able to adjust the volume or experience directional sound (the sound in front of you appears louder than one that coming from somewhere else). CICs are typically not recommended for individuals with adequate low frequency hearing or for people with severe hearing loss.
