Types Of Hearing Aids
A hearing aid is a special type of device used by people with any sort of a hearing disability to overcome the problem.
There are many types of hearing disabilities, some are minor and some are severe and they maybe caused due to any reason. Whatever the intensity or the reason, a hearing disability can easily be over come by the help of these wonderful devices known as the hearing aids.
Not every one is privileged with the gift of hearing. Usually what happens is that the ears of these under privileged people can not catch the sound waves let alone to detect them. A hearing aid enhances the ability of these people to catch the waves and convert them into sound for these people.
The concept of hearing aids is not a new one. They were invented almost more than half a century ago to help those with a hearing loss. In past they were simple and were not as effective as the hearing aids of today.
Today, there is a large variety of hearing aids for the people suffering from a hearing disability to choose from. These hearing aids are much advanced and are accompanied by other accessories as well.
There are basically four types of hearing aids. Following are the types of hearing aids:
In The Ear (ITE) Model
This type of hearing aid is suitable for any kind of hearing disability from mild to severe. These hearing aids are large in size. This hearing aid completely covers the central ear and is the most effective type.
The ITE hearing aid due to its large size can accommodate comparatively larger sound amplifiers and has a directional microphone and other accessories. ITEs have a long life battery and despite of their large size are easy to handle.
Using Hearing Aids
- Hearing Aids
Man is a social animal, and to be social the sense one needs the most is to hear what the people around him/her are saying.
In The Canal (ITC)
In the canal or ITC type hearing aids are used in the case of a mild hearing loss or a moderate one. They are extremely small and are designed specifically to fit into the canal of the ear.
Because of the very small size of the ITC hearing aids it is not possible to function it with your hands.
A remote control is usually accompanied with the device for the purpose of changing the battery and to control other functions. The battery of ITCs has a long life but not longer than the battery of ITE hearing aids. They are also much more expensive.
Various Eye Defects
- Eye Defects
A defect of vision due to non-sphericity of the cornea. The defect is corrected by using cylindrical surfaced lenses.
Completely In The Canal (CIC)
The completely in the canal
(CIC) types of hearing aids just like ITC type hearing aids are only effective
for people with mild to moderate hearing loss. But they are lot smaller than
the ITC type of hearing aid. The ITC hearing aid is so tiny that it is not
possible to remove from the ear with fingers and a tiny wire is used to pull it
out of the ear.
They too like the ITC type are difficult to detect when in the ear and one can not change the battery and adjust the settings due to their tiny size, therefore a remote is also accompanied with these hearing aids. They just like the ITCs are more costly than the ITEs.
LASIK Eye Surgery For Loss Of Vision
- LASIK Eye Surgery
LASIK eye surgery is refractive surgery for correcting nearsightedness, farsightedness, and astigmatism. This surgery is carried out by ophthalmologists using a laser.
Behind The Ear (BTE)
Just like the ITE hearing aid, the behind the ear (BTE) types of hearing aids are effective for any hearing impaired individuals suffering from mild hearing loss to those with a severe loss. The BTEs are also in large size. It has a large part that fits right behind the ear.
It is attached to a smaller piece that fits inside the ear via a large visible tube. The BTE is a highly adjustable hearing aid with full of strength.
Unlike the CIC and the ITC, which can not be detected due to their extremely small size, the BTEs are visible because of their large size. The BTE hearing aids are better suited for the children. They are less expensive than the small ITC and CIC.
Recently a newer version of the BTE has been released which is called the behind the ear open fit. This new type of BTE is much smaller than the typical BTE types.
Contact Lenses And Eyeglasses For People With Loss Of Vision
- Contact Lenses
Contact lenses- I dont think there is any need to introduce any one with what this invention is? Few years back may be we would have needed an introduction into functions of contact lenses.
- How To Choose Eyeglass Frames
Eyeglasses or spectacles, in early days used only for correcting vision errors, but these days it is used for both; vision correcting tool as well as a fashion accessory.
