What are hearing aids?

If you’re new to the world of hearing loss, then you might want to know a bit more about hearing aids in general. They are battery powered devices that help you to hear. They work to improve your hearing by fitting into the ear and projecting sound. They are made up of a microphone, amplifier and receiver to make this happen.

What kinds are there?

Now, you may also be interested in knowing more about the kind of hearing aids that are available.

  • In the ear (ITE): ITE hearing aids fit inside of the outer ear bowl. They generally have a plastic casing that contains all of the electrical components. They’re usually used for adults with mild or severe hearing loss.
  • Behind the ear (BTE): A BTE hearing aid is the traditional kind that you may be used to seeing. It fits behind the ear and channels sound into the ear. They can be great for those with mild-to- severe hearing loss.
  • In the canal (ITC): ITC hearing aids are small and fit within the ear canal. They are very small and discreet. They can be perfect for adults with mild to moderately severe hearing loss but difficult for children.

What types of batteries are there?

Because hearing aids rely largely on their batteries to run smoothly, it’s also useful to know more about the batteries themselves. Of course, your hearing instrument specialist will advise you specifically on what will be best for you.

Rechargeable

Some of the newer styles of hearing aid are fitted with rechargeable batteries. When it comes to recharging, this is often done at night when the hearing aid isn’t in use. These are most commonly found in the BTE styles of hearing aid.

Standard Batteries

The more common style of battery is the standard disposable kind. They’re often called button batteries. They are zinc-air batteries and are activated when the sticker sealant is removed.

How long do they last?

When it comes to your hearing aids and the suitable batteries, you may want to know exactly how long they are going to last. It is said that they can last anywhere between three and 20 days – this will depend on the exact style of hearing aid. See more detail below;

  • Yellow Size 10 Batteries: Three to seven days, used with completely in canal (CIC)
  • Brown Size 312 Batteries: Three to 10 days, used with ITC and mini BTE
  • Orange Size 13 Batteries: Six to 14 days, used with BTE and ITE
  • Blue Size 675 Batteries: Nine to 20 days, used with power BTE

Signs they need changing

Your hearing instrument specialist will be able to advise you as much as possible here, but you may need to change the battery once or week or once every few weeks. Some of the signs that you may need to change it include distorted sound or having to turn up the volume, as well as hearing the low battery beep.

How can I make my battery last longer?

If you want to make sure that you’re getting the most possible use out of your hearing aid batteries, it’s a good idea to ensure that they last as long as they can. To preserve the life of your battery, any time you’re not using it, you should leave the battery door open – particularly at night. If you know you’re not going to be using it for a long time, remove the battery altogether. Also avoid storing them near high temperatures as this can reduce the life span.

Caring for your hearing aid battery
