A wide range of technology and a host of features are available in each hearing aid style. The cost of hearing aids generally depends on the technology and the number of features the instrument has and not necessarily on the style selected. Today’s digital hearing aids are typically offered in various levels, such as basic, entry, advanced or premium level. Within each level, different technology and features are available.
Basic digital hearing aids generally require the wearer to make some manual adjustments in certain listening environments, such as turning a volume control up or down, or pushing a button to change listening programs. In contrast, a premium or more advanced hearing aid responds automatically to changes in the listener’s environment, making changes based on the signals being detected by the hearing aid. The hearing aid wearer is not required to make any manual changes. As the level of the technology increases in hearing aids, so does the availability of advanced features. Examples of some of the advanced features found in today’s digital hearing aids are shown below.
When selecting a style the following is considered:
- The degree of the hearing loss
- Manual dexterity and visual abilities
- Patient budget
- Cosmetics
- Skin sensitivities
- Anatomical/medical considerations
Styles of Hearing Aids
Hearing aids are available in many different sizes and styles thanks to advancements in digital technology and miniaturization of the internal components. Many of today’s hearing aids are considered sleek, compact and innovative – offering solutions to a wide range of hearing aid wearers.
Receiver-in-the-Canal (RIC)
The most common hearing that that is used!
A RIC hearing aid consists of a tiny housing containing all electronics except the receiver, which is positioned behind the ear. A thin tube connects the housing to the receiver, which is worn in the concha (bowl-shaped portion) of the ear.
It’s a small and discreet unit but powerful enough for treating mild to moderately severe hearing loss.
Behind-the-Ear (BTE)
A BTE device is curved to match the contour of the ear and rests directly behind the ear. The housing, which contains all the electronics, is encased in plastic and connects to the ear canal with a thin, clear tube or ear mold.
Though more visible than other styles, the BTE is simple to use, making it a popular choice for children. It’s powerful enough for all types of hearing loss.
Invisible-in-Canal (IIC)
The entire hearing aid sits inside the ear canal, making it practically invisible.
Since this device sits so deep inside the ear, it is less likely to pick up background noise, such as wind, but is prone to earwax blockage. The size of this device means it cannot fit any additional features and takes the smallest batteries. This model can treat mild to moderate hearing loss.
In-the-Ear (ITE)
This hearing aid is designed to fill the outer portion of the ear, and is larger than those worn in the ear canals. It is less discreet, but the size allows for more features and makes the unit easier to adjust.
A bigger battery translates to longer life and means those with severe or profound hearing loss can benefit from this style.
