| There are many different types of hearing aids on the market
today to fit the different needs and designs desired by hearing impaired
individuals. One of the main choices to be made is to go with a digital
hearing aid or an analog hearing aid. Analog hearing aids are the oldest
type of hearing aid on the market, having been around since hearing aids
were developed. Although batteries tend to last longer in analog hearing
aids since there is less electronic equipment within it, digital hearing
aids are the best choice since they have many more features that are
beneficial to those who have lost their hearing.
Benefits
Digital hearing aids have better gain processing than analog hearing
aids since it has more flexible gain processing capabilities. This means
that individuals wearing the hearing aid will not experience as much
discomfort in their ear when high intensity sounds are going on around
them. Digital hearing aids have more channels available to them and more
compression capabilities so it weeds out the low level environmental
noises and gives more comfort to the individual wearing it.
In addition, there is less feedback in a digital hearing aid than in an
analog hearing aid since there are more filters built into it, such as the
cancellation system. This means that users will not have the feedback from
jaw movement or being close to certain objects that analog hearing aid
users will experience from time to time. Another helpful feature is the
use of directional microphones in digital hearing aids. This helps to
pinpoint the sounds that are beneficial for the individual to hear and to
reduce the environmental noise that is picked up as well. For instance, in
a quiet environment, the microphone may be working omni-directionally
since there is not very much sound to pick up on in that environment. If
the individual then walks into a crowded, noisy room and begins to speak
to a friend, the microphone in a digital hearing aid will switch to a
directional microphone so that it better picks up on the person's voice
that is in close proximity and reduces the sounds of all the other people
in the room.
Digital hearing aids also come in a variety of different sizes and
shapes to match the desires and needs of the individuals who use them.
They can be placed completely in the ear canal, partially into it, or in
the ear, which means that it fills the ear cup with the device and has a
part that goes into the canal. It also comes in the traditional style that
has one piece in the ear and one behind it. Choose according to
which style you like.
