HEARING IMPAIRMENT IN CHILDREN
When your child does not respond to the sounds in the environment, does not give you eye contact on his name calling and his speech appears to be delayed, then your child may have a hearing deficit.
How do I confirm that my child may have deafness?
Take your child to an Audiologist to check the hearing. Depending on the age of the child, the audiologist will decide on the method for testing his hearing.
For instance -
- Neonates and infants could be tested by BERA (Brainstem Evoked Response Audiometry) which is an objective test.
- Children in the age group of 2 - 3 yrs could be screened using free - field audiometry.
- Children above 3yrs could be conditioned and then a full - fledged audiogram can be done.
What is an audiogram?
An audiogram is a graph of intensity v/s frequency. This is a subjective test by which one can find the hearing thresholds of the child over a range of speech frequencies i.e. 125Hz - 8000Hz. It helps to determine not only whether your child is deaf and but also in which range of sound frequency, the hearing is most impaired. It also determines how severe is the hearing loss in your child. This can help in determining the further course of action while treating the child.
What should I do after the audiological evaluation?
After the audiological evaluation, the child has to be fitted with a suitable pair of hearing-aids, which will enable the child to use his residual hearing to its maximum potential.
Which hearing-aids would be the best for my child?
An experienced audiologist would be able to prescribe suitable hearing-aids by keeping in mind the following parameters.
- The hearing thresholds of the child.
- Responses of the child to the auditory stimulus.
- Tolerance level of the child.
What the causes of deafness in a child?

Apart from that, problems to the child at the time of the birth, syndromes, infections in the newborn period, hereditary causes may also cause hearing loss. Most of the times the cause of isolated deafness in a child is unknown.
