What is a hearing aid?
- A hearing aid is a small electronic device that your child wears behind her ear(s). It makes some sounds louder.
- A hearing aid has three basic parts:
- Microphone
- Amplifier
- Speaker
- The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.
- Hearing aids are secured to your child’s ears with earmolds.

What are earmolds?
- An earmold is a small piece of soft plastic that is custom made for your child’s ear.
- Earmolds fit inside your child’s ear canal.
- The earmold helps hold the hearing aid in place.
- Because young children grow very fast, earmolds will need to be replaced as your child grows. Replacement will occur more often during early infancy.
- Earmolds will last longer for older children.
