What is a hearing aid?

Widex Passion™
(actual size: 22mm)

A hearing aid is an electronic device which consists of a microphone, a receiver (i.e. loudspeaker) and an amplifier microchip powered by a tiny battery. Thanks to recent developments in digital technology and advanced electronic design, today's hearing aids can be so small they are virtually invisible in the ear canal.

Although a hearing aid may not provide its wearer with a completely "normal" hearing, it should be able to provide considerable benefit in overcoming the effects of a hearing loss.

The different types of hearing aids


Completely-in-canal (CIC) hearing aids are, as the name indicates, placed deeply within the ear canal. Despite the small size, this hearing aid type contains the latest technology of equal quality to larger models.
     
In-the-ear (ITE) hearing aids. Unlike behind-the-ear hearing aids, in-the-ear hearing aids are placed inside the ear and consist of only one part (the shell) into which the electronics are built. The shell is custom-made from an impression of the user's ear canal.
 
 
     
Behind -the-ear (BTE) hearing aids consist of a plastic casing containing the electronics, from which the amplified sound is fed through a clear plastic tube to an earmould. The earhook on the behind-the-ear hearing aid connects to this tube which forms the connection to the custom made earmold worn in the user's ear.
     
Open-Fit. Similar in style to a BTE hearing aid, an open fit hearing aid uses a combination of unique elements specially designed to deliver the sound from the hearing aid into your ear as comfortably and discreetly as possible. All of the elements come in various sizes, which enable this model to be instantly custom fit.
