How Do Hearing Aids Work?


Most people have seen a hearing aid at one point or another, but few have stopped to think about how they work. Hearing aids help people with hearing loss. Their job is to do the following:

  • Collect the sounds from all around, 
  • Make the sounds louder and clearer, and 
  • Then to deliver the sounds into the ear.

Some hearing aids are called BTE (behind-the-ear) and others are called ITE (in-the-ear). The one you opt for boils down to preference. Younger children often have the behind-the-ear type, which comes in an assortment of cool colors. Older children might have an in-the-ear version, which is much smaller and fits snugly in the ear.

If someone has a more severe hearing problem, they might use a device called a cochlear implant. This is a very tiny piece of electronic equipment that is put into the cochlea during an operation. It helps the damaged or destroyed hairs by turning sounds into electrical messages that stimulate the hearing parts of your brain directly.

Cochlear Implants versus Roger Systems: Different Types of Hearing Aids

In order for someone to hear with a cochlear implant, they have to wear a speech processor, which looks a bit like a hearing aid. In order for a child to have a cochlear implant, the following criteria apply:

  1. The child needs to be at least one year old, 
  2. He or she should have severe or profound hearing loss in both ears, and 
  3. He or she should be unable to hear well with their hearing aids.

Cochlear implants can also be used with Roger systems. The best way to describe this hearing system is by explaining what they do: 

  • If you suffer from hearing loss, it can be hard to work out who is talking in a crowd or to understand what is being said when the speaker is a long way from you. 
  • This is where the Roger systems come in. Roger systems have two parts: 
  1. One part is a little wireless microphone that is worn by the person speaking. 
  2. When someone has a Roger system, they hear the talker’s words clearly and directly in their hearing aids, making it easier to hear in noise.

Beltone hearing aids cover the broad spectrum of devices and are available in forty locations across the globe.
