China is the country with the largest number of people with hearing disabilities in the world, with nearly 30 million people with hearing disabilities. Childhood is a critical period of auditory language development, hearing disability leads to children's speech development disorders and affects their emotional, psychological and social communication and other ability development, causing a heavy burden on the family and society. 
1. Factors of hearing loss in children
1.Genetic factors
About 60% and 70% of children's hearing loss is caused by genetic factors. Evidence suggests that offspring born to consanguineous or closely related individuals have a higher probability of hearing loss.
2.Intrapartum factors
These include preterm birth, low birth weight, neonatal asphyxia, and neonatal jaundice.
3.Infection
Maternal infection with rubella, cytomegalovirus, etc., during pregnancy may cause hearing loss in newborns. Meningitis, measles, and mumps can also cause hearing loss.
4.Ear diseases
Common ear conditions, such as cerumen plugging (earwax buildup), secretory otitis media effusion, and suppurative otitis media, can also cause hearing loss in children.
5.Noise
Prolonged loud use of personal audio devices such as smartphones, **, etc., can cause hearing loss. Short-term, high-decibel noise, such as fireworks, can cause permanent hearing loss.
6.Medications
It is used for a variety of drugs such as neonatal infection, antimalarial, anti-tuberculosis and anti-cancer drugs, which can cause hearing loss because of their ototoxicity.
2. The dangers of hearing loss
Children's hearing loss has the most significant impact on their language Xi;In addition, the child's overall cognitive ability, social skills, attitude towards life, and self-esteem will also be affected. Children with hearing loss who do not receive ** often do poorly in Xi, leading to poor job performance and reduced employment opportunities as adults. Communication difficulties can leave children feeling angry, depressed, and lonely, creating lasting emotional and psychological trauma that can affect the entire family. More broadly, hearing loss will have a detrimental impact on the socio-economic development of countries.
3. How to avoid hearing loss
More than 30% of childhood hearing loss is due to diseases such as measles, mumps, rubella and meningitis, which can be avoided through preventive immunization and good hygiene Xi.
The first is to prevent immunization, and many diseases that cause hearing loss, such as congenital rubella, meningitis, mumps and measles, can be prevented through immunization.
The second is to strengthen maternal and child health measures to prevent preterm birth, low birth weight, neonatal asphyxia, neonatal jaundice, congenital cytomegalovirus, rubella virus and other infections.
The third is to popularize hearing screening for newborns, infants and children, and early detection and diagnosis of children with congenital or late-onset hearing loss, so as to provide a basis for early intervention. Fourth, it is best to implement interventions before the age of 6 months, including hearing aids, hearing reconstruction measures such as cochlear implants, and speech training. Hearing screening for newborns can detect hearing loss at an early stage and provide timely and effective intervention, which can avoid stunting as much as possible and promote the development of social, educational and social life skills.
Fourth, it is common to hurt the ears and Xi habits
Some bad Xi and bad actions in life may accidentally damage the baby's ears and hearing.
1.Ear droppings
Earwax, commonly known as "earwax", is a yellowish viscous substance secreted by the cerumen gland of the external auditory canal. Earwax becomes flake-like or viscous grease after it is dried by air, and it can be called the "flower messenger" of the eardrum and the external auditory canal, which can not only block the "invasion" of dust and small flying insects, but also buffer noise, prevent the inflow of external moisture, and inhibit the breeding and reproduction of bacteria.
2.Blow your nose vigorously or suck your nose
Blowing your nose too hard, especially blowing your nostrils together, may cause the bacteria in the nasal cavity to directly invade the tympanic cavity through the eustachian tube under the action of pressure, injuring the ear, and in severe cases, earache, middle ear empyema, and even tympanic membrane perforation, ear pus, hearing loss, etc. If children like to sniff and even form regular nasal sucking movements, it will increase the probability of the baby suffering from otitis media, and in severe cases, it may be complicated by brain abscess, which is very dangerous.
3.Nose often runny and ignore it
Sinusitis is often triggered by colds in children, and sometimes the nasal discharge often runs for a long time, and this situation cannot be left untreated. Because of colds, acute sinusitis, acute pharyngitis, bacteria or viruses are easy to enter the middle ear through the eustachian tube to cause inflammation, otitis media is secretory otitis media at first, if not timely, it can often develop into acute purulent otitis media.
4.Wear headphones for long periods of time
Wearing headphones often, especially listening to high-decibel sound for a long time will damage the hearing organ of the inner ear and produce noise-induced deafness, so people who like to wear built-in headphones to listen to CDs should master the "60-60-60" principle, that is, the volume should not exceed 60% of the maximum sound, the continuous listening time should not exceed 60 minutes, and the external sound should not exceed 60 decibels;People who wear built-in headphones to listen to ** should follow the "80-90 rule", which means that the volume does not exceed 80% of the maximum volume and the continuous listening time does not exceed 90 minutes.
