Early signs of hearing impairment in young children

Deaf children are children who have suffered hearing damage to varying degrees. Because the hearing organs are damaged, children cannot see the world of sound, cannot hear voices, and cannot form language. If a child with hearing impairment is detected early and is interested in supporting with special methods, it will help them have the opportunity to develop their inherent abilities.

1. Causes of hearing impairment

The causes of hearing impairment can be caused before, during and after birth:

1.1 Causes of pre-birth

  • Congenital: Ear malformations, ear rim defects
  • Due to infection during pregnancy (influenza, measles or other viral diseases).
  • A family history of genetic hearing impairment causes the ear to develop abnormally.

1.2 During childbirth

  • Premature calving less than 6 months
  • Low weight less than 2kg
  • Brain injury caused by obstetric intervention.

1.3 Post-birth

  • Due to infections: Purulent meningitis, measles, mumus ,encephalitis.
  • Diseases of the ear caused by inflammation: Acute or chronic otitis.
  • Due to auditory neuro toxicity due to certain drugs (gentamicin, streptomycin, quinin..)
  • Head injuries, head injuries such as concussions or skull fractures.

When the child suffers from the above diseases, if there are signs of poor hearing, purulent discharge or pain in the ears, parents should take the child to the examination and treatment in the specialized entotitis units.


Premature babies born under 6 months are at risk of hearing impairment

3. Diagnostic measures

Hearing measurement

3.1 How to check your child's hearing from 6 months to 3 years

To recognize signs of hearing impairment in babies, it can be determined through the following steps:

Step 1: Let the child lie on his back in bed, the person tries to stand on the top of the child, half a meter away.

Step 2: Perform applause, or shake the dice… to make a noise to see if the child is turning in that direction. Do it again 3 times and observe the reaction of the child.

3.2 Check the hearing of children over 3 years old

Step 1: Let the child sit and turn his back on the tester, in turn seal each side of the ear and face to the opposite side to say each single word, the intensity of speaking normally for the child to repeat. If the child repeats 4-5 times correctly, it can be considered normal listening.

Step 2: Do it again with the opposite ear.

Step 3: If the child is found to be misrepresented, or does not repeat the sound of speech, it is necessary to take the child to reputable specialized units to measure hearing.

3.3 Hearing measurement

The purpose of hearing measurement is to accurately assess a child's hearing, to find out the causes of hearing loss. From there, choose a remedy: let the child wear a hearing aid or surgery. Help choose the right type of hearing aid for your child.
