For most people the ability to listen is a normal part of life, but for some of us that one of life's blessings has gone, or is going. For these less fortunate people something must be done. Fortunately for these people there is something that can be done. A hearing aid is a small device placed in and behind the ear that magnifies or amplifies the sound around them so that it can be heard by the wearer who is hard of hearing.
Early designs of such a machine were very primitive indeed and modern versions have developed a lot since. Originally they were known as ear trumpets or ear horns and had to be placed by hand by your ear as it acted as like a sound funnel.
It was positioned to the ear where the smaller end of the cone fitted in the ear and the larger end picked up the sound waves and compacted the sound waves that were picked up and resulted in a stronger sound energy impact on the eardrum of the listener. This meant that those who struggle to hear could hear a better quality of clear sound. For those who struggled to hear things at a normal volume, it was a wonderful invention.
Aids to hearing have come a long way in the present day since their invention in the sixteen hundreds by Jean Leurechon (1591 to 1670). Back then they were made of several different things. More expensive models were made from silver, whereas cheaper options were made form wood or iron (and did not work as well as the more expensive types). Some could even be made of animal horns, and some of the more extreme came from snail shells!
There are two main and different sorts of the aid. There is the in the ear aids (ITE), and also the invisible in canal aids (IIC). In the ear aids are worn in the outer ear bowl which is known as the 'concha', whereas the invisible aids are completely out of view even if you stare down the ear looking for it.
Each individual who has an in-the-ear has had it custom made for them. You will most likely receive an ITE if you have a problem with your hearing as they are prescribed to people who have slight hearing deficiencies right through to those with very serious hearing loss. They do, however, have problems with whistling noises and feedback in which sound leaks and is re-amplified over again (particularly with noises of a high frequency).
The second kind of aid is the type that is invisible even if you were to look directly down the ear. These are Invisible in canal aids (IIC). When worn they are not visible because its fit is much deeper in the canal of the ear than other types. The aids shell is custom fit to the individual and thus achieving a comfortable fit for the wearer. They are not usually suited to elderly people, but those who are better described as middle age or younger.
The hearing aids that fit behind the ear are cheaper as they do not need to be made from a mould like ITE and IIC aids. It is the fact that they must be custom made that makes them cheaper or more expensive. Therefore; if you need a hearing aid, go to your doctor and see what he has to say.
