The Early Hearing Detection and Intervention (EHDI) guidelines, implemented in the year 2000, sought to ensure all children get the help they need for their hearing loss. The goal of this program is for all babies to be screened for hearing loss no later than one month of age; if a baby does not pass the screening, they receive a diagnostic hearing test no later than three months of age; and children diagnosed with hearing loss undergo intervention services no later than six months of age.
The CDC estimates that with the EHDI program in place, about 98% of all children born in the United States have had their hearing screened, meaning treatment can start as early as possible. For many babies, this means wearing hearing aids.
What Hearing Aids Are Available for Infants?
Hearing aids amplify sounds to a level a baby can easily hear.
They consist of four main parts:
- The microphone, which picks up sounds in the environment.
- The processor, which amplifies sounds.
- The receiver, which delivers sound to the ear.
- The battery, which powers the device.
There are many styles of hearing aids available. A pediatric audiologist will make a recommendation based on the child’s type and degree of hearing loss. Most babies are fit with behind-the-ear (BTE) hearing aids because the earmold can easily be replaced as a child grows.
How Are Earmolds Made?
The plastic or silicone earmold that connects the BTE hearing aid to the ear is fitted by taking an impression of the ear. When the earmold no longer fits a baby comfortably, a new one needs to be made.
When Do Infants Start Wearing Hearing Aids?
Infants can start wearing hearing aids after they receive a diagnostic hearing test, as early as two to three months of age. Babies can have their hearing tested while they sleep using auditory brainstem response (ABR) testing, which determines how well the inner ear and brain pathways for hearing are working.
Then, an audiologist uses a computer to program the hearing aid to meet the needs of the child.
How Often Should Babies Wear Their Hearing Aids?
The goal is for a baby to wear their hearing aids during all waking hours. However, it will take time for them to get used to wearing them. A pediatric audiologist will give specific instructions to help a baby get used to wearing the devices all day long. This will help them build essential communication skills for later in life.
