Individuals with mild to moderate hearing loss are candidates for completely-in-canal (CIC) hearing aids – the smallest of the hearing aid options available today. CIC hearing aids are different than other devices due to their size, custom fit and location in the ear canal. This style of hearing aid has many advantages, as well as a few disadvantages when compared to other hearing aid styles.
Advantages – Completely-in-Canals are small and their size and fit hold several aesthetic as well as listening advantages. Due to the lack of bulk, these devices work automatically without the need for controllers and other people may not ever notice that you’re wearing a CIC unless they peer directly into your ear canal.They may be more comfortable to wear due to their custom fitting. A few completely-in-canal 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.
Disadvantages – 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. You will also be limited to omnidirectional sound, meaning you will experience all sound as if it’s right in front of you. Moreover, CICs are not powerful enough for people with major hearing loss.
