It is important to monitor your baby's speech and language development as well as responses to sound.
The following checklist provides a guide to hearing and language milestones. If you are concerned about your child's hearing or speech language development please arrange to have your child's hearing tested. Your doctor can arrange for a referral to an appropriate location for testing your child's hearing.
|Birth to 3 months||Reacts to loud sounds|
|Becomes quieter when hearing familiar voice or sounds|
|Makes cooing noises|
|Responds to speech by looking at speaker's face|
|3-6 months||Turns eyes or head toward sounds|
|Starts to make speech-like sounds|
|Laughs and makes noises to indicate pleasure and displeasure|
|6-9 months||Babbles, eg 'dada', 'mama', 'baba'|
|Shouts/vocalises to get attention|
|Will often respond to 'no' and own name|
|Responds to singing and music|
|9-12 months||Imitates speech sounds of others|
|Understands simple words, eg 'ball', 'dog', 'daddy'|
|Turns head to soft sounds|
|First words emerge|
|12-18 months||Appears to understand some new words each week|
|Follows simple spoken instructions, eg 'get the ball'|
|Points to people, body parts or toys when asked|
|Continually learns new words to say although may be unclear|
|18-24 months||Listens to simple stories or songs|
|Combines two or more words in short phrases, eg 'more food'|
|2-3 years old||Understands longer sentences|
|Listens from a distance(in quiet)|
|Follows directions that include 2-3 steps|
|3-4 years old||Processes complex sentences structures|
|Re-tells longer stories in detail-5 or more sentences|
Because the first 6 months of life is crucial for the development of the hearing centres of the brain and for learning. The first month is most important because that is when the hearing centres in the brain develop and grow rapidly and efficiently.
Thus ,it is best to test your child’s hearing at birth , soon after birth.
Your baby can be tested on day 1 of birth.haring screening can be done by 1 month of age, hearing loss diagnosed by 3 months of age and intervention begun no later than 6 months of age.
It is best to have your baby’s hearing tested by a professional.
Because these tests use only loud sounds so babies with lesser degrees of hearing loss can be missed out. Apart from this they provide additional clues (vibration, visual clues) so they may see and feel the movement of stimulus.
New born Hearing screening is testing a baby for hearing loss after birth or soon after birth.
Hearing loss cannot be seen by looking at the baby .a hearing loss could be present despite typical appearing outer and middle ear structures.
New born Hearing screening allows you to ascertain the presence or absence of hearing loss in each ear. It is recommended because the earlier you detect a hearing loss, the earlier you can begin intervention.
Early intervention will give your child a better opportunity to reach her potential so that they can participate in main stream society with her typical hearing peers.
Evoked Otoacoustic emissions (EOAE)
Measurement of OAEs is used clinically as an objective test of normal cochlear function at all ages and it has been adapted as a test of cochlear function in newborns.
Automated auditory brainstem response (AABR)
The ABR is used clinically as an objective, diagnostic measure of the integrity of the ear and auditory nerve pathway up to the brainstem. The ABR measure has been adapted as a neonatal screening test by automating the procedure, reducing the test time and establishing an estimate of auditory thresholds.
Hearing screening provides number of benefits:
The high-risk criteria used are:
