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.
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.
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.
A toddler can be evaluated using two tests. The first one is visual reinforcement audiometry abbreviated as VRA. During this test the child is trained to look towards a source of sound. When the child responds correctly, he is rewarded by use of visual objects like a flashlight or a moving toy. This test is done on children between 6 months to 2 years of age.
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.
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.
