Hearing Aid: Comparison

Completely in the Canal (CIC)

CIC or mini-CIC hearing aids are designed completely within the ear. These are popular because they are more discreet as the smallest type of hearing aids. CIC hearing aids are usually a suitable option for many adults with mild to moderate hearing loss. They are also less likely to pick up wind noise, which may be beneficial for patients who spend a great deal of time outdoors.

However, CIC hearing aids have some downsides. They use very small batteries, which need to be replaced more frequently and can be difficult to place. They typically do not have additional features that some patients may need, like volume controls or directional microphones. Finally, CIC hearing aids can be prone to earwax clogging.

In the Canal (ITC)

ITC hearing aids are custom-molded to fit partially in the ear canal to improve mild to moderate hearing loss. While slightly more noticeable than CIC models, ITC hearing aids are still rather inconspicuous. Like CIC models, ITC hearing aids can be difficult to handle due to their small size and are susceptible to earwax clogging. However, they offer a few more features that some patients need, like volume control.

In the Ear (ITE)

ITE hearing aids are custom-made to fill either the entire outer ear or just the lower part—these options are known as “full shell” and “half shell,” respectively. This is a better option for people who have more severe hearing loss thanks to more available features such as directional microphones. Additionally, ITE hearing aids tend to use larger batteries that can last longer. One downside, however, is that this style may pick up more wind noise.

Behind the Ear (BTE)

BTE hearing aids connect over the top of the ear, with a majority of the hearing aid resting behind the ear. This is connected to a small, custom earpiece that directs sound to the ear canal. While traditionally BTE hearing aids are the largest type, newer models are more streamlined and inconspicuous. They are better options for those with severe hearing loss and can amplify sound better, with features like directional microphones and rechargeable batteries available.

Receiver in the Canal (RIC) / Ear (RITE)

RIC and RITE hearing aids look similar to BTE hearing aids, but a wire hooks over the ear rather than tubing. Aside from this difference, RIC and RITE are overall similar to BTE hearing aids for the patient, with more or less the same pros and cons.

Open Fit

Open fit hearing aids are another variation of BTE hearing aids. Open fit styles leave more of the ear canal open, allowing for low-frequency sounds to naturally enter the ear while high-frequency sounds are amplified. Patients with high-frequency hearing loss often prefer this option because their own voices sound more natural and their ears don’t feel plugged by the hearing aid. However, some find that open fit hearing aids are difficult to insert in the ear.
