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 second test used on a newborn is called evoked otoacoustic emissions abbreviated as EOAE. This test uses a small, flexible plug which is fitted in the ear of the baby. Through this plug, sound is sent. The plug has a microphone, which records the otoacoustic responses of the ear in reaction to the sounds produced. This test is also done when the baby is asleep and it is also painless.
One of the methods used on infants is referred to as behavioral audiometry. This method involving observation of the child behaviors in response to the sound they are subjected to. The doctor may also use a different additional test if need be.
Moving to toddler stage, two kinds of tests are used here too. To start with, there is visual reinforcement audiometry or VRA. This test involves a child being trained to look at a source of sound and their response is observed. If they respond as expected, then they are rewarded with visual objects like a moving toy flash light. This test is meant for children in the age bracket between 6 months to 2 years.
The other test used on toddlers is play audiometry. In this test, an electrical machine is used to relay sound at varied pitches and volumes into the ears of the child. This test can be modified to a game depending on the age group of the child. The child is requested to do something with a moving toy every time he hears the sound. In most cases, this test will rely on the cooperation of the child, which 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.
Pure Tone audiometry is a test used for hearing evaluation in children. An electric machine is used in this method to generate sounds with varied pitches and volumes. This sound is directed to the child ears through earphone and asked to react with his hand ear in response to what he hears.
