Behind the ear hearing aid
When you think of a hearing aid, the first image that pops to your mind is this banana shaped plastic part placed behind the ear, connected to something placed within the ear (earmold). This type of haring aids are called behind the ear hearing aids. You can still see BTE hearing aids that are quite big and massive. On the other hand, you can also find some really neat designs for tiny BTE hearing aids. Some of the hearing aids look just like bluetooth ear set.
This is the part located behind the ear. It contains the “brain” of the hearing aid with all the best technology and features. It holds the batteries too. The bigger the batteries, the longer the device will last without replacing them. All the buttons are also located here, along with the microphone that receives the tones, sounds and voices from the surrounding.
One of the greatest advantages of the BTE is the size of its buttons, battery and battery cover. Comparing to other hearing aid types, it is fairly comfortable to use its buttons and replace the batteries. It‘s important, especially with kids and elders. You can save lots of problems and head aces just by making battery replacing simple.
Another thing you should think of is that the BTE devices are kept clean from all the ear secretion and sweat. On devices that you put inside the ear, this can become a real issue. The BTE usually stays clean and protected. Since you want the hearing aid to work for years, keeping it clean helps a lot.
The separation between the case and the earmold is very useful
cases. For instance, for a child, that his ear keeps on growing, all
you need is a new earmold rather than getting a brand new hearing aid.
It is also great for adults, when you want to check out a new hearing
aid, just use your old earmold to see if the newer hearing aid is good
Moreover, behind the ear hearing aids keeps the case clean. It really helps to protect the delicate technology inside the case.
