BOA (Behavior Observation Audiometry) Hearing Test

Share This Post


Behavioral Observation Audiometry (BOA) is a type of hearing test that is used to assess the hearing of infants and young children who are too young to cooperate with other types of hearing tests. BOA is also used to assess the hearing of children with disabilities or other conditions that may make it difficult for them to cooperate with other types of hearing tests.

During a BOA test, the audiologist will observe the child’s behavior in response to a variety of sounds. The sounds may be pure tones, speech sounds, or environmental noises. The audiologist will look for any changes in the child’s behavior that indicate that they have heard the sound. For example, the child may turn their head towards the sound, widen their eyes, or startle.

The audiologist will record the softest intensity at which the child responds to each sound. This is called the child’s hearing threshold. The child’s hearing threshold is measured in decibels (dB). The lower the number, the better the child’s hearing is.

The audiologist will then plot the child’s hearing thresholds on an audiogram, which is a graph that shows the child’s hearing sensitivity across different frequencies. The audiogram can be used to determine the type, degree, and configuration of the child’s hearing loss.

BOA is a safe and effective test for infants and young children. It is typically more time-consuming than other types of hearing tests, such as pure tone audiometry, but it is often the only way to assess the hearing of young children who are unable to cooperate with other types of tests.

BOA is used to diagnose and monitor hearing loss in infants and young children. It is also used to assess the effectiveness of hearing aids and other treatments.

Here are some of the benefits of BOA:

  • It can be used to test infants and young children who are too young to cooperate with other types of hearing tests.
  • It can be used to test children with disabilities or other conditions that may make it difficult for them to cooperate with other types of hearing tests.
  • It can provide accurate and reliable information about a child’s hearing sensitivity.

If you have any concerns about your child’s hearing, or if they have a history of ear problems, it is important to see an audiologist for a hearing assessment. BOA is a valuable tool that can help diagnose and monitor hearing loss in infants and young children.
