Hearing Aid Info And All About Them

Hearing aids are small devices which are put into the ear to magnify and amplify sounds around the wearer to be heard by the wearer that cannot hear as well as normal people. For lots of us, listening to the world around is normal and just a part of our every day lives. For a few, however, it is not. For those who cannot hear as well as they might, a hearing aid is used.

Early designs of these little machines included such contraptions as ear horns or ear trumpets. These were cone-shaped and could be likened to a funnel for sound.

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.

Ear horns and trumpets were manufactured from different materials. More expensive horns were made of silver, whereas the cheaper options came made from sheet iron or wood. Some were made from animal horns or even snail shells! Though historical aids to hearing were astonishing in their time, modern day hearing aids have come a long way since the ear trumpet inventor Jean Leurechon (1591 to 1670) had his mathematical streak of genius.

Still in the modern day, there are two main kinds available. You can get an ?In the Ear? (ITE) aid, or you can get an ?Invisible In Canal? (IIC) aid. The first of these is placed into the outer ear bowl (also known as the ?concha?) and can be seen, but is sometimes hidden by the ear itself. The second of these is out of sight even to he who stares down the ear to find 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).

IIC (Invisible In Canal) aids are just that; they are placed into the canal of the ear and are invisible as they are placed so deep down into the ear that they cannot be seen in every day life. They also do not need to be removed at night as they are only removed when they are replaced by the doctor. These are also custom made from a mould as is the previous type of aid. They are best suited to the middle age, but traditionally are not worn by the elderly.

ITE and IIC kinds are often the more expensive kinds rather than those that fit behind the ear as they are moulded to the patients ear. A mould is taken of the persons ear and then the aid is made from that mould. They are made by doctors at hospitals or general practices. So if you need help listening to the world around you, your first port of call should be your local doctor.
