Children undergo hearing screening tests after birth, and in fact, their hearing begins to form in the mother's body. It can sense their mother's heartbeat and hear their parents' conversations. So now more and more children are receiving prenatal education in their mother's womb. After birth, a child's hearing also develops slowly. How much normal is a child's hearing? What is the specific developmental process of a child's hearing?
How normal is a child's hearing
Checking a child's hearing is between 25 and 30dB, which is normal data for hearing sound. However, normal people speak at around 40 to 50 decibels, so even with mild hearing loss, children can hear sound, but they cannot hear or speak clearly. If you are not a professional, you cannot feel it. Parents can train their babies' hearing more to improve their ability to hear various sounds.
The specific developmental process of children's hearing
When children are born into this world, their hearing development also progresses gradually, which can be roughly divided into the following stages:
When Baobao was born, he had a feeling for the sounds around him. Sometimes, sudden sounds can startle babies.
When babies are around 3 months old, they feel happy when they hear their parents' voices. He can look in the direction of the sound source and also make "ah" or "oh" sounds in response to his parents.
By around 7 months old, babies are already very familiar with sound. In addition to the voices of parents, babies are already able to distinguish various sounds, such as doorbell ringing, phone ringing, TV sound, etc.
When the baby is 9 months old, even if the sound is not loud, he can already hear sounds coming from other rooms.
When the baby is 12 months old, he has already learned to ignore noise. For example, when he is focused on playing with toys, he may not be able to hear the noise coming from around him. At the same time, such a big child can also understand some words.
During the hearing test of a newborn baby, there may be abnormal hearing, so mothers don't have to worry. At this time, it may be due to the lack of amniotic fluid flowing out of the baby's ears. Generally, a follow-up examination after one month is mostly normal. Mothers should cultivate their babies' hearing skills by buying bell ringing toys, which can also help develop their concentration. The above is an introduction to how normal a child's hearing is, hoping it can help you.
