Care & Maintenance of Hearing Aids | Ear Science Institute Australia

A hearing aid is a small electronic device that makes sounds easier to hear. It can help people who have hearing loss. It usually includes:
The microphone receives sounds from around you. The amplifier makes the sound signals stronger and sends them to your ear through the speaker.
Your hearing aids will be programmed by an audiologist to match your hearing loss. They will help you hear the sounds you struggle to hear, without making them too loud.
It can take time for your brain to get used to how things sound when using hearing aids. You might need the audiologist to adjust your hearing aids while you are getting used to them.
If you think you have hearing loss, ask your doctor to refer you to an audiologist or visit a hearing clinic for a hearing test.
An audiologist will do a full check of your hearing. Based on this, they can tell you if you have hearing loss, and if hearing aids are likely to help you.

Others have only one part that connects to an ear mould or ear tip through a thin tube. Some are bigger, more powerful and can be used by people with severe hearing loss.
These hearing aids sit completely in your ear. They are made to fit the shape of your ear. There are different types, depending on if they sit:

There are two main types of implantable hearing devices:

Speak to your audiologist to find the right type of hearing aids for you.
If your baby has hearing loss, hearing aids are important for their hearing and speech development (Opens in new tab).
You might need to get new ear moulds often as your baby grows. If your baby tries to pull their hearing aids off, try using hats and headbands to keep them in place.
Make sure that your baby can't put the battery or the ear mould into their mouth.
Hearing aids may be funded through the Hearing Services Program (Opens in new tab) or the National Disability Insurance Scheme (Opens in new tab). This depends on your age and eligibility.
If you have private health insurance, check if you are covered for hearing aids. Hearing aids are not funded by Medicare.
Ask your doctor or audiologist for advice on how to get hearing aids.
Wear your hearing aid as your audiologist recommends.
It may be helpful to ask your audiologist:
Keep batteries away from children as they are dangerous if swallowed.
