The whole process of hearing development for babies aged 0 to 3 years
After a person is born, they can only learn to speak if they can hear it. It is immediately clear how important hearing is for children’s language development.
But because children can’t speak yet, it is not easy to detect early hearing impairments.
Therefore, parents are better to understand some hearing test methods, brake early detection of abnormal hearing, and take necessary measures in a timely manner.
The relationship between children’s hearing development and language development Children’s language development and hearing development are inseparable. Whether the hearing is normal, the language development test is a “barometer”.
A person must first have hearing before speaking through language learning.
A normal child (normal and normal, never dumb), if born after being placed in an environment not in contact with anyone, no one will speak, and will never speak.
A hearing impaired child, even if he lives in an environment where someone speaks to him, but cannot learn to speak because he cannot hear. This is the so-called “ten deaf and nine mute” principle.
0-3 years old children’s hearing development process 0-30 days * After hearing the sound in the awake state, turn their eyes and head to find the sound source.

4 commonly used hearing detection methods.
1.When the child is awake, the adult shakes the copper bell 10-15 cm behind his ears, but he cannot let him see the copper bell.
Observe whether the child immediately stops activity or blinks after hearing the bell.
If the above response appears, hearing is present, if there is no response to the ringtone, hearing is abnormal.
2.The slap slap slap violently at a distance of about 1 meter from the child, and observe whether the child immediately stops activity or blinks when he hears it, and at the same time there is a startle.
If these reactions occur, hearing is present.
Calling for the name When the child gently calls his name on the back of him for 5-6 months, or use a bamboo board, gong, etc., to check whether the child quickly turns his head to the sound source.
If the child does not turn his head to find the sound, there is no response, presumably a hearing problem.
4．Otoacoustic Emission This is a large area screening for newborns that can be tested while the newborn is sleeping.
This screening method has a short operating time, does not require any electrodes to be inserted into the head, and does not cause any damage to the brain tissue of the newborn.
If you can pass, you can temporarily judge that your hearing is normal.
Early manifestations of hearing impairment in children * Under 3 months, there is no response to sudden loud sounds.
* At 3-6 months, no sound source will be searched for the sound that appears.
* At 9-12 months, do not follow the instructions of adults.

Intimate tips: 1.
When children are 2 years old, they will not express their needs or understand the words of adults, there may be hearing problems.
2.If hearing-impaired children can be identified early, they can be treated and trained early, and their treatment is relatively simple.
It can improve the complete recovery of hearing in some children, even if they use residual hearing to learn language, and they will not speak in the future.
Method for promoting hearing development in children 1.
Let children listen to the rich sounds in life. Rich sounds such as walking, door opening and closing, running water, sweeping, talking, car, airplane, wind, rain, etc. These natural environment sounds promoteHearing development is very beneficial.
Therefore, let your baby hear these sounds more.
Intimate reminder: If the noise is too noisy, such as the sound of construction work, the noise of the machine, etc., it will cause certain damage to children’s hearing, and you must avoid it in your life.
2.He usually listens to children more often. * When holding a child, it is best to use the left-hand holding position to keep the child as close to the mother’s heart as possible. The armor can clearly hear the mother’s heartbeat.
* For newborns, you can attach sound-producing toys with different sound quality or tones in the crib to stimulate hearing cells and promote hearing development.
* Usually talk softly with children, hum or play some classic music with soothing rhythm and beautiful melody.
* Hang a wind chime on the balcony of your home, let the wind blow the chime to make a pleasant sound.
* For children to hear the sound of various objects falling to the ground, such as balls, chairs, books, pencils, cans, wooden boxes, paper boxes, etc.

* Fill some water in the bottle and tap the bottle gently to let children listen to different sounds from the bottle.
Intimate reminder: Do not choose toys that are too large, and pay attention to distance when placing them.
Strong sound stimulation can easily damage the eardrum of children. Excessive noise will also cause hearing fatigue in children, which will reduce children’s perception of speech interchange.
