Every new life is the result of the mother’s hard and long ten-month pregnancy and her best efforts to reproduce. Therefore, every child is his or her own heart, and the family's love and concern for the child will naturally become stronger. Today's technology and medicine are very advanced.



What kind of check-up should I do if I suspect my baby has poor hearing?

Hearing screening, but it is also possible that the baby’s hearing is good, but the test is affected. Failing a hearing screening does not mean that the child must have hearing problems or be unable to hear. There is amniotic fluid residue in the baby's ear canal, or the baby is moving during the examination, there are noises around, or there is fluid in the middle ear, etc., which will cause the baby to fail the hearing screening.

You can wait until 42 days for re-examination. The general hearing test process is a 3-day initial screening and a 42-day re-screening. If there is no problem with general hearing after 42 days, the baby will need to go to the hospital for a comprehensive hearing test at 3 months of age. Failing the hearing screening does not mean that you cannot hear sounds. Children with different degrees of hearing loss respond to different sounds. People with mild hearing loss respond to normal speech sounds. People with severe hearing loss can only respond to loud sounds. Parents can observe their children's normal reactions to sounds.

Since children are not as able to cooperate with subjective hearing tests as adults, it is more difficult to make correct judgments about children's hearing. Generally speaking, it is necessary to combine the subjective and objective hearing test results with each other, verify each other's objective hearing results, and combine the characteristics of children of different ages to conduct a comprehensive analysis before making a diagnosis, rather than drawing a conclusion based on one result alone. The examination includes:
1) Objective hearing test: It needs to be performed while sleeping and is suitable for children who cannot cooperate with subjective tests. There are auditory brainstem response (ABR), 40Hz auditory related potential (40Hz-AERP), auditory steady-state evoked response (ASSR), otoacoustic emissions (OAE), and middle ear acoustic impedance.

2) Subjective hearing test (pediatric behavioral audiometry): conducted in a awake state, using different testing methods for children of different ages, which can reflect the condition of the entire auditory pathway. Behavioral observation audiometry (BOA): suitable for children within 2 months; visual reinforcement audiometry (VRA): suitable for 6 months - 2.5 years old; game audiometry (PA): suitable for 2.5 - 5 years old.
