What Are Hearing Aids & What Do Hearing Aids Do?

Posted by admin in Uncategorized at September 18, 2009

In the past hearing aids have always had a stigma attached them, we often think of them as the clumsy, ugly looking things that fit over the outer ear and go into the ear but with modern technology today they have decreased rapidly in size and now there are ones that fit directly into the ear and are so small that they aren’t even noticeable.

How Does A Hearing Aid Work?

Whatever the type or size of hearing aid they all work on basically the same principal, they have a built in microphone that amplifies sound from the environment which is then routed through the hearing aid to the ear canal.

The hearing aid can usually be adjusted for varying degrees of hearing loss, this is called the gain and is measure on hertz, severe hearing loss will require a higher gain level and smaller amounts will be needed for those suffering from a mild amount of hearing loss.
