The purpose of a hearing evaluation is to determine if an individual has hearing loss. At East Coast our Doctors of Audiology, will complete a thorough hearing health history to include medical history and possible hearing problems.
The Audiologist will do different tests that will determine:
Hearingloss often occurs gradually and it can be difficult to identify early signs; therefore it is important to get your hearing checked annually to monitor any changes in hearing.
Watch for the following signs of hearing loss:
Evoked Otoacoustic Emissions (EOAE) A test that uses a tiny, flexible plug that is put into the baby’s ear. Sounds are sent through the plug. A microphone in the plug records the otoacoustic responses (emissions) of the normal ear in reaction to the sounds. There are no emissions in a baby with hearing loss. This test is painless and it often takes just a few minutes. It is done while the baby sleeps.
Auditory Brainstem Response (ABR) A test that uses wires (electrodes) attached with adhesive to the baby’s scalp. While the baby sleeps, clicking sounds are made through tiny earphones in the baby’s ears. The test measures the brain’s activity in response to the sounds. This test is also painless and takes only a few minutes
Behavioral Audiometry A screening test used in babies to watch their behavior in response to certain sounds. The EOAE and ABR Tests may also be used.
Play Audiometry A test that uses an electrical machine to send sounds at different volumes and pitches into your child’s ears. The child often wears some type of earphones. This test is changed slightly in the toddler age group and made into a game. The toddler is asked to do something with a toy (such as touch or move a toy) every time the sound is heard. This test relies on the child’s cooperation, which may not always be possible.
Visual Reinforcement Audiometry (VRA) A test where the child is trained to look toward a sound source. When the child gives a correct response, the child is rewarded through a visual reinforcement. This may be a toy that moves or a flashing light. The test is most often used for children between 6 months to 2 years old.
Pure tone Audiometry A test that uses an electrical machine that makes sounds at different volumes and pitches in your child’s ears. The child often wears some type of earphones. In this age group, the child is simply asked to respond in some way when the tone is heard in the earphone.
Tympanometry A test that can be done to help find out how the middle ear is working. It helps to find any changes in pressure in the middle ear. This is a hard test to do in younger children because the child needs to sit very still and not be crying, talking, or moving.
