Hi and welcome to the
Ultimate Hearing Aid Guide.
ITE (In-The-Ear) Hearing Aids
As their name suggests, ITE hearing aids are worn inside the ear. To enable them to fit properly, they usually have to be custom-made for every individual, creating a molded unit that sits inside the ear without friction or the possibility of becoming dislodged.
In terms of appearance, ITE hearing aids are invisible from behind, unlike BTE (Behind-the-ear) models, and they can also be camouflaged by making the cases in colors which resemble the wearer's skin tone. This makes them a slightly less visible hearing aid option, although they will generally be visible from the side, no matter how their appearance is masked.
ITE heading aids come in a range of different styles, which vary by size and technology. Firstly, there are very small ITE devices, which may be referred to as IIC (Invisible-in-the-canal) or CIC (Completely-in-the-canal). These tend to be more advanced devices, and have been engineered to be as small as possible. They are inserted deep into the wearer's ear canal, in theory collecting more powerful sound waves as they hit the pinna and penetrate the canal. However, because of their small size, these hearing aids tend to be relatively low-powered, and are associated mainly with moderate or low levels of hearing loss.
IIC and CIC hearing aids are also generally more suited to younger users with greater manual dexterity, as they can be harder to access when battery changes or cleaning are required. And manufacturers generally recommend removing these devices on a daily basis, so users need to be able to access them without any problems. Thanks to their comparatively inconspicuous design, they are popular among people who have mild auditory problems and don't want their hearing aid to be visible.
The second type of ITE hearing aids are called ITC (In-the-canal) devices, and are positioned much closer to the opening of the ear canal. In fact, they tend to rest on the inner part of the outer ear bowl, making them more visible, but often more comfortable and esy to access. ITC devices are also usually larger than IIC or CIC versions, which makes them easier to manipulate and maintain, and also gives them longer battery lives, which some users will find appealing.
With a bit of extra size, ITC hearing aids are often able to accommodate additional features compared with those of inner ear varieties, such as better detection of sound based on direction, and dials to control features like volume or noise cancellation. At the same time, the extra power they can mobilize also makes ITC hearing aids a more common suggestion for those with moderate to severe hearing loss.
There are also intermediate hearing aids which bridge the gap between the various ITE designs. They will tend to be smaller than ITE/ITC models, but still have some elements showing from the outside. And they boast greater power levels than IIC/CIC hearing aids, making them more suitable for those with moderate or severe hearing loss.
Whichever model of ITE hearing aid users go for, these devices always include the microphone inside the hearing aid unit, unlike with RIC devices, where the two are separated. Which one is the better option to go for? That depends on the needs of the user and their personal tastes. The great advantage of ITE hearing aids is that they are shaped to suit the dimensions of every individual ear, as well as their hard-to-see fit. So, they will typically be comfortable to wear, and suitable for image-conscious wearers (although more powerful ITE models are far from invisible when in place).
On the negative side, ITE hearing aids often fail to deliver the most powerful performance levels, making them slightly less appropriate for those with a greater degree of hearing loss. Being worn inside the ear, they are also associated with moisture damage and "occlusion", which is the sensation of the wearer's ears feeling "clogged up". These problems can be mitigated by looking after ITE hearing aids diligently, but they are still an issue for some users, and are worth bearing in mind when making a selection.
