What You Need to Know Before Buying a Hearing Aid

You finally get up the nerve to go to the hearing aid office and get your ears tested. They break the news that you need a hearing aid. Your mind is swimming with visions of having to wear that huge thing on your ear. How could this have happened? Why me?! And then they start telling you about all of the different types you can get.

All that terminology just goes right over your head. Don't they know your in shock! How on earth can you make a decision when you don't even know what they're talking about!

There are hundreds of different hearing aids. It can be a very complicated world of technological terms. Sometimes, those of us that work with hearing aids all the time can forget just how foreign they can sound to you.





To make matters worse, the manufacturers like to call things different names, so they sound like something different. No wonder there's so much confusion!

I am going to try to unravel some of the mystery for you. When you get down to it, there are really only a few terms you need to understand.

Half Shell (HS) The Half Shell fills about half the bowl of your ear. They are able to have a good deal of power and features, use a smaller battery, but are more cosmetically appealing.In the Canal (ITC) The next smallest size is the custom ITCMini Canal (MC) Smaller than the ITChearing aid, the custom mini canal uses a smaller battery and has even less power available. Features can also be more limited.






 These are available on most BTE, OE, ITE, Half Shell, and ITC styles of hearing aids. They are the best feature you can have on your hearing aid for hearing in noisy places, such as restaurants. (They reduce sounds from behind, so that it does not interfere with the sound in front of you) Directional microphones can be automatic; they automatically turn on when the sound level in the room gets too loud.

 Some are also be adaptive, which means they can follow moving sounds, or reduce several different sounds at the same time.

Noise Reduction - Noise reduction doesn't really reduce noise, it reduces amplification in the frequencies where there is noise and no speech.




If there is a fan running in the background, the hearing aid will not amplify it as much as it will speech. When the hearing aid finds both speech and noise at a frequency, you still get both. More advanced the hearing instruments manage noise better by breaking the frequencies up into smaller pieces.
