HEARLINK is a hearing testing centre in Australia that conducts auditory tests to identify the degree of hearing loss. Hearing
test for children is also conducted here to identify hearing impairment problems if any.



Auditory tests are very important as these tests determinethe hearing capacity of a person. Hearing test for children is
conducted to identify hearing capacity of the child.



Is your child facing hearing problem? Yes, then you can take your child to clinic that conducts auditory tests and hearing loss
children. This test is undertaken to identify the degree of hearing loss. These tests are performed by an audiologist with the
help of an audiometer. This device is useful in determining a person’s hearing sensitivity at different levels of sound.

Auditory tests are part of ear examination which gives evaluation of a person’s ability to hear. The hearing ability is
measured with the ability of sound to reach the brain. This test also helps to determine the kind of hearing loss, the person is
suffering from. Hearing test for children who have complex or developmental abilities are difficult to administer and
interpret.The tests that are selected to assess hearing capacity in infants and young children depend on the age of the child
and ability to undertake the hearing test and information that is required about the child’s hearing capability.

Children are assessed of hearing capability on combination of behavioural tests and physiological tests. Let us know about
these tests in depth:



   1. Behavioural Tests – These tests are based on observing a change in child’s behaviour in response to the sound.
      (a) BehaviouralObservation Audiometry (BOA) – This noisemaking test is carried out for infants below the age of 7
          years and above this age who cannot respond when they hear the sound.
      (b) Visual Reinforcement Orientation Audiometry (VROA) – This test is like a hearing test for children in whom the
          child’s hearing capacity is determined who is between 7 months or is of 3 years age.
      (c) PlayAudiometry – This test is used to test the hearing capacity of children of 3 years of age or above.

   2. Electro-physiological tests –This test helps to determine that which part of auditory system is responsible for hearing
      loss and also it measures physical response of a specific part of the auditory system.
      (a) Oto-Acoustic Emission Testing (OAE)– This test is carried out to get an idea about how hair cells in the cochlea
          are working.
      (b) Brainstem Evoked Response Audiometry (BERA) –This test gives information related to electrical activity that is
          generated from sound’s response along the nerve pathway to the brain.
      (c) Electro-cochleography (ECochG or EcoG)– This test is carried out in hospital under an anaesthetic and provides
          information about the functioning of the cochlea and start of the nerve pathway to the brain.
      (d) Tympanometry and acoustic reflex – This test gives information about the middle ear behind the eardrum. This
          indicates that whether eardrum is functioning in a normal way or not.


Hearing loss children tests are conducted for newborn babies before they leave the hospital. These tests don’t consume lot
of time and painless & are often done while the baby is sleeping.Early identification of hearing loss in babies at early stage
allows parents and doctors to plan for better treatment and intervene early to get the problem solved. These tests are done
by an audiologist.
