The detection of hearing injury and deafness should be done since someone is still a baby. The detection can be done by parent in a simple way. This can be done by making a simple experiment toward the baby.
In checking the hearing ability of a baby, parent can do it by making a sound around him and see whether there is a response from him or not. When there is a response, then the baby has a normal hearing ability. Typically, not all cases of hearing loss at birth are known. This is because not all parents check their baby's hearing ability. So, they do not know whether the baby has this hearing disorder or not.
There are some indications that parents need to know to detect hearing loss in infants. For example, the baby sleeps nicely although there is loud sound around him or if a six-month-old baby can babble but he can not respond when there is sound. Those are two examples that sign a baby has hearing loss.
The detection of hearing injury and deafness has to be started before the baby out of the hospital or at the age of two days. Or, the hearing loss should be detected at the latest at the age of 1 month if the baby born outside the hospital. In this matter, the diagnosis of deafness should have ascertained before the age of 3 months so that the installation of hearing aids can be initiated since the age of 6 months.
Further, there are some things that make an infant has high-risk hearing loss and deafness. The things are a baby with a birth weight less than 1500 grams, a pregnant woman who uses drugs such as tuberculosis drugs and antibiotics, and a pregnant woman who received chemotherapy. Instead of those things, other things that make infant has high risk hearing loss are bacterial meningitis, cholestasis and the use of ventilator for more than five days.
When a baby has three of those things then it is likely he will experience deafness fifty to sixty times more than non-risk infant. Additionally, infants that are treated in Neonatal Intensive Care Unit (NICU) have ten times the risk of hearing loss compared to those who are not treated in the NICU.
Since hearing loss detection is an important thing to do, parent should pay attention to this matter very carefully. In this matter, they should do the detection in order to make sure that their baby does not have this hearing disorder.
