Types Of Hearing Aids

When buying a hearing aid these days you are likely considering a digital model as these produce better audio quality and can be adjusted to your specific needs.
You will find numerous models available to select from and, if your hearing loss is mild (probably age related), you will have to find a good balance between cosmetic and comfort factors and price. As you can't know in advance what you will find comfortable or acceptable it is vital that there is a trial period during which you can return the hearing aid.
There are two basic types of hearing aids, those that fit externally behind the ear and those that fit internally in the ear. On the whole the cost of hearing aids is more the smaller they are.
Over The Ear Models
These fit behind the ear and a small almost invisible tube connects to an earmold that fits in the ear canal. This is usually the least costly type of hearing aid and its other benefits include:

• As the earmold is separate from the device itself it can be changed at will to find the most comfortable fit.
• It is larger so is easier to handle, will have easier to use controls and probably more features.
• Will use larger batteries so battery life will be better.

On the other hand:

• Most visible type of hearing aid.
• Inconvenient when undertaking physical activity.
• Can be affected by sweat and moisture in general.
• Inconvenient having two pieces to put on and use.

It is also possible to buy "open fit" over the ear models. These are usually smaller and use a comfortable ear piece rather than an earmold. Their size means that they are less noticeable which is a major factor for many wearers. However they are only suitable for mild/moderate hearing loss.
In Ear Hearing Aids
With these the hearing aid is one unit the goes in the ear. Difference types are worn:

• In the ear - These are made to fit the bowl-shaped area of the outer ear and will be visible in a face to face situation.
• In the canal -This type fit in the upper part of the ear canal and whilst they are less visible they can still be seen by other people.
• Completely in the canal. These very small aids fit deep into the ear and are virtually undetectable.

In general the smaller a hearing aid is the fewer features it will have, the harder it will be to handle and the shorter its battery life will be.
Advantages are:

• Provide the best appearance, the smallest in ear devices will not be seen.
• Enable normal use of telephones.
• All in one unit is easy to use.

Against this:

• Difficult to use and operate for persons with dexterity or eyesight problems (small size and battery).
• Require more maintenance and have poorer reliability than external types.
• Vulnerable to wax and moisture.
• Can be a problem fitting in anyone with small ears.

The prices of hearing aids are usually high if purchased via an audiologist but big savings can be made through online shopping.
