A physician usually carries out a total physical tests, asks about the medical history of your child before he can continue with a hearing evaluation examination. The child ability to hear has several tests that can be conducted. The several tests vary depending on the childs age and also on their level of comprehension. The following pointers illustrate further on the tests carried out on your child on the basis the child age.
A newborn can be evaluated used two types of tests. These tests can be used alone or together. The first test is auditory brainstem response abbreviated as ABR. This test uses wires which are joined to the scalp of the baby using an adhesive. The test is carried out when the baby is asleep to avoid distraction. Clicking sounds are applied through small earphones in the ear of the baby. The test usually measures the brain activity in response to the sounds produced. This test takes only a few minutes and it is painless.
The other method is known as evoked otoacoustic emissions. It is abbreviated as EOAE. In this method, plugs, which are small and flexible, are fitted in the baby ears. These plugs are meant for conveying sound to the baby. The microphones on these plug then records the otoacoustic responses of the ear in response to the sounds produced. This test is painless.
Infants are also evaluated using the same tests as the newborn and another test is also used which is referred to as behavioral audiometry. This test is based on observing the behavior of the child in response to certain sounds produced. The physician may also choose to do additional tests if need be.
Babies between the age of six months and two years usually use two tests. The first one is known as visual reinforcement audiometry (VRA). The child is taught to focus on a source of a produced sound. The child enjoys the test since it is formulated like a game that has a reward system in form of visible objects such as toys in motion or flashlights. Once the child makes the correct response, they are rewarded.
The second test used on toddler is known as play audiometry. This involves the use of electrical machine to relay sound at different pitches and volumes into the child ears. This test can be done in form of a game based on the child age group. In this test, a child is asked to operate a moving toy in reaction to the sound they hears. The bad thing with this test is the cooperation of the child which in most cases is not guaranteed.
Children who fall in the age bracket of 3 to 4 years are evaluated using Tympanometry test. This is also known as impendance audiometry. It is used to determine the functionality of the middle ear of the child. It is used for detecting any pressure change and not for examining the ability of a child to hear. When carrying out this test, a child should remain still without crying, moving or talking.
Another test used for hearing evaluation in older children is Pure Tone audiometry. In this test, an electric machine is used to produce sounds at varied pitches as well as volumes onto the ears of the child. The child is asked to respond with his hand when he hears the tone through the earphone.
