The microphone picks up sounds and sends them to a small computer with an amplifier that makes the sound louder. The hearing aid will make some pitches of sound louder than others, depending on the shape and severity of the hearing loss. Your audiologist will connect the hearing aid to a computer program in order to adjust the sound for your child's needs.
After sounds are made louder, they go through the
earhook – a small plastic piece that holds the hearing aid on over the top of the ear – to an earmold that is custom made for your child.
All hearing aids have the same basic parts: a microphone, digital amplifier and speaker.
Behind-the-ear (BTE) hearing aids (shown below) are the preferred style for babies and children.
These hearing aids are recommended for babies for a number of reasons:
Earmolds are made from a mold or impression of your child's ear. They are made from soft materials and fit in the outer ear and ear canal.
hearing aid fitting and evaluation for infants and young children.
Hearing aid gain is the amount of volume or loudness increase at each frequency that is provided through the hearing aid.
When the amount of hearing loss is different across frequencies, the audiologist must adjust the gain of the hearing aid differently for each frequency.
Language learning begins within the first months of a baby's life. It is important for babies with hearing loss to start using hearing aids as soon as possible. Hearing aids may be small, but there are many important things to learn about them. It is important to learn about hearing aids and devices so you can help your child.
