The baby’s sense of hearing begins to be formed when the baby is still in the womb at the age of 8 weeks. The formation of the baby’s sense of hearing will be completed by the time the fetus is 24 weeks old. And by the time the fetus is 25 weeks old, he can already hear the sounds around him, including the voices of his parents. So at 25 weeks of pregnancy, communicate between parents and the fetus even though it is still in one direction. Talking to the fetus or singing to the fetus, will make a pleasant moment during pregnancy. Likewise with the fetus, he will feel happy and peaceful if he hears soft voices from his parents, and of course this will be very good for his development.

When a baby is born into the world, the development of the sense of hearing is divided into several stages:
- When they are born into the world, babies are aware of the sounds around them. Even babies will feel shocked when they hear a sudden loud sound.
- When a baby is 3 months old, he will feel happy if he hears the voice of his parents. He will be able to turn to the source of the sound and as much as possible he will reply to the voice of the old man with babbling “ah” or “oh”
- When a baby is seven months old, he or she is well acquainted with the origin of sounds. Apart from the voices of their parents, babies are also able to hear and differentiate and know other sound sources around them. Like when a baby hears a bell, the sound of television etc.
- By the time the baby is nine months old, the baby is able to hear sounds coming from another room, even though the sounds are not loud.
- By the time the baby is 12 months old, the baby is able to overcome the noise when he wants to concentrate on his toys. By this time babies understand several words and groups of words
Doing the Baby’s Sense of Hearing Test
Parents can do a baby’s hearing sense test to find out whether the baby’s hearing power is good or not. The hearing power test for babies is classified according to the age of the baby
- For babies aged three months and under, parents can do a hearing test whether it is functioning properly or not. The test can be done by clapping your hands on the back of your baby’s head. If the baby is surprised at the clapping sound, the baby’s sense of hearing is functioning properly. But even if your baby is not surprised, don’t worry too much, try to repeat the above test several times or at different intervals
- For babies between the ages of four and six months, test them by calling their names. Try to pay attention when called by name whether the baby turns to you or reacts to the sound of his name calling. In addition, pay attention to whether he is also turning his head or eyes to sounds that attract the baby’s attention
- For babies between the ages of six and nine, hearing power tests can be done by paying attention to the baby’s response to sounds around him. Notice if the baby reacts and responds to telephone sounds, house bell sounds, television sounds and others
- For babies aged 12 months and over, the test can be done in a way that the baby is asked to show familiar objects that are around or in books.
Babies born very prematurely will be prone to hearing loss, as are babies with parents or a history of hearing problems
