For the physician to do a hearing evaluation on your child, he will have to perform a complete physical examination and medical history. Besides this, there are other various types of hearing tests that can also be used to examine your child ability to hear. Some of these tests can be used on every age while others are only meant for the specific age of the child and his level of understanding. Below are some of the tests and how they are used on different ages of children.
On a newly born, two types of examinations can be carried out. These examinations can be done either alone or both at the same time. ABR stands for Auditory brainstem response is the initial test. Wires that are glued to the baby scalp are used on this examination. When the baby is awake they may destruct the physician and prevent the test from being carried out well so the test is conducted when the baby is asleep. On the babies ear a set of earphones are placed and they make a clicking sound. The test seeks to find out the level of brain function ability in relation to the applied clicking sounds. The great news is that the child is not subjected to any form of pain.
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.
