Hearing aids are used to assist people with hearing loss improve hearing. Hearing aids come in a variety of styles and colors. All hearing aids have microphones, amplifiers and speakers to accomplish the job. The microphone “hears” the sound, processes it and sends it to the amplifier. The amplifier makes the sound louder, without distortion and sends it to the speaker, which passes the sound on to the inner ear. Hearing aids can sit outside or inside the ear. Here is a list of several popular styles of hearing aids.

Invisible-in-canal (IIC) hearing aids

Just as the name implies, these hearing aids are virtually invisible. They sit inside the ear canal and patients use a small stick to help insert and remove them. These are custom-molded to sit deep in the ear canal, close to the eardrum. This style does not work for all types of hearing loss and some people do not like the feeling of having something deep in the ear canal. Because of their size, these also can be expensive.

In-the-canal (ITC) hearing aids

These hearing aids also are custom fit and just partially visible. They are slightly larger than invisible-in-the-ear units and can offer directional microphones, volume controls and a longer battery life. These hearing aids work for anyone with mild-to-severe hearing loss.

In-the-ear (ITE) hearing aids

This style of hearing aid is popular and works for most people. The hearing aid sits partially in the ear canal and also in the lower part of your outer ear. Because it’s a bit larger, it’s easier to insert and remove than the smaller units. These also are custom-fit and have directional microphones, a volume wheel and a button to change programs.

Behind-the-ear (BTE) hearing aids

There are several styles of behind-the-ear hearing aids. Each has the actual unit sitting behind your ear, with either a thin tube or wire that hooks over the top of your ear. Many come with a custom earpiece that sits just inside the ear canal. These units may be larger than those that fit in the ear, but because of the advances in technology, they are smaller than you may think. They’re easy to maintain and work for nearly any type of hearing loss.

Digital hearing aids

Almost all of the hearing aids made today are digital. This allows for optimal customization as well as improved sound. The microphone takes in the sound, which is then converted to digital audio. The unit then analyzes the sound and provides the best amplification without distortion. The sound is sent to the inner ear, which passes it on to the brain. Prior to digital technology, hearing aids were analog. Some analog models are still available, but essentially only amplify sound.

Today’s styles of hearing aids can work with Bluetooth devices, store specific programs, reduce background noise and improve telephone audio. Some even have remote controls! When deciding on a hearing aid, be sure to consult with your hearing healthcare professional to determine what device would be best for you.
