Styles
Styles of hearing aids include:
Completely-in-the-canal style hearing aids (CIC): these are the smallest and most cosmetically discreet. The CIC instruments fit completely in the canal and are custom-made. There is a clear nylon string to help with insertion and removal. They are powered with a #10 hearing aid battery.
In-the-Canal style hearing aids (ITC): these are larger than the CIC devices. They fit within the ear canal and are custom-made. They are powered with a #312 or #10 hearing aid battery.
In-the-Ear style hearing aids (ITE): these are larger than the ITC style. They fit in the ear, filling the entire "bowl" of the ear. They are custom made. The customization along with the lightweight and compact size makes these instruments comfortable and easy to manage. They are powered by a #13 or #312 battery.
Conventional Behind-the-Ear style hearing aids (BTE): the processing components are housed in a case that fits behind the ear. Sounds enter the instrument, are amplified, and travel through a tube that is contoured over the top of the listener's ear and into an earmold inside the ear. BTEs are durable, easy to handle and maintain, and can be easily adapted for use with the wide variety of assistive listening devices. They are powered with a #675 or #13 battery.
Open Fit and Receiver In the Canal Behind the Ear Style: These are similar to the conventional BTE but are much smaller, making them more discreet. A very small tube leads to the ear canal making this option much more cosmetically appealing while offering superior sound quality.
Digital Technology Levels, Hearing Performance and Price Range per Instrument.
(All levels of technology are available in all hearing aid styles and sizes.)
Level 4. Premium
These instruments offer the most advanced technology and options. Hearing speech is the priority. Best for active individuals who are frequently in noise. Automatic noise control and volume with adaptive directional microphones to handle multiple noise sources. Have Bluetooth options. Highest performance for clarity and noise contro. $2900 - $3400
Level 3. Advanced
These instruments are suggested for practical minded, active people who are often in noise. Automatic noise control with adaptive directional microphones handle one noise source. Auto noise control and volume. Very good clarity with noise cancellation. $2200 - $2800
Level 3. Standard
These instruments are best for low to moderately active people occasionally in noise. Automatically switches from "surround sound" to "directional" to help in noise. Has standard non-speech noise reduction. $1500 - $2100
Level 1. Basic
These instruments are best for the less active person who is rarely in noise. Manual directional microphones and volume controls are standard. $995 - $1400
Are there different styles of hearing aids?
There are three basic styles of hearing aids. The styles differ by size, their placement on or inside the ear, and the degree to which they amplify sound.
-
Behind-the-ear (BTE) hearing aids consist of a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss.
A new kind of BTE aid is an open-fit hearing aid. Small, open-fit aids fit behind the ear completely, with only a narrow tube inserted into the ear canal, enabling the canal to remain open. For this reason, open-fit hearing aids may be a good choice for people who experience a buildup of earwax, since this type of aid is less likely to be damaged by such substances. In addition, some people may prefer the open-fit hearing aid because their perception of their voice does not sound "plugged up." - In-the-ear (ITE) hearing aids fit completely inside the outer ear and are used for mild to severe hearing loss. The case holding the electronic components is made of hard plastic. Some ITE aids may have certain added features installed, such as a telecoil. A telecoil is a small magnetic coil that allows users to receive sound through the circuitry of the hearing aid, rather than through its microphone. This makes it easier to hear conversations over the telephone. A telecoil also helps people hear in public facilities that have installed special sound systems, called induction loop systems. Induction loop systems can be found in many churches, schools, airports, and auditoriums. ITE aids usually are not worn by young children because the casings need to be replaced often as the ear grows.
-
Canal aids fit into the ear canal and are available in two styles. The in-the-canal (ITC) hearing aid is made to fit the size and shape of a person's ear canal. A completely-in-canal (CIC) hearing aid is nearly hidden in the ear canal. Both types are used for mild to moderately severe hearing loss.
Because they are small, canal aids may be difficult for a person to adjust and remove. In addition, canal aids have less space available for batteries and additional devices, such as a telecoil. They usually are not recommended for young children or for people with severe to profound hearing loss because their reduced size limits their power and volume.
