The incidence of deafness accounts for about 50% of deaf people in China, and genetic deafness accounts for about 85% of congenital deafness, most of which are autosomal recessive inheritance. Relevant literature reports that in the normal population, the rate of consanguineous marriage is only 2%, while among patients with hereditary deafness, 70% are consanguineous marriages. It can be seen that consanguineous marriage is the main factor in concurrent genetic deafness. As many as 300,000 children under the age of 7 in my country are deafened due to irrational use of antibiotics.


Will moderate hearing loss in children affect their intellectual development?
Hearing has nothing to do with intelligence. But intellectual development will be affected. The longer the hearing impairment lasts, the long-term lack of sound and language stimulation will cause intellectual development to be delayed. The more sounds you hear, the more external information your brain needs to receive for development, including sound information. The more information your child receives, the smarter he will be. Therefore, children who are deaf should wear Hearing Aids as early as possible and cooperate with language training.


The more severe the degree of deafness, the more obvious the impact.
* Hearing loss below 25dB generally has no language barrier and will not affect normal language communication.

* People with an average hearing loss of 26-40dB have no difficulty hearing ordinary speech sounds, but they may find it difficult to listen in situations where many people are in meetings, and smaller sounds are difficult to hear. This situation is more prominent if the high frequency drops significantly. If infants and young children have this kind of hearing loss, it will affect the development of language and intelligence to varying degrees.

* The average hearing loss is 41~55dB, and it is difficult to understand speech at normal volumes. If it occurs in infants and young children, it can cause language development delays and affect children's language learning.

* The average hearing loss is 56~70dB, and it is difficult to hear loud voices. If it occurs in infants and young children, it can cause significant delays in language development and abnormal pronunciation.

* The average hearing loss is 71~90dB. You can perceive loud sounds, but you cannot distinguish speech sounds, which can lead to speech disorders.


1-5 years old is a period of rapid growth in children’s language development. However, children with hearing impairment cannot learn to speak by listening, and their language development is slow. Even if you are born with normal hearing, you may gradually lose your hearing due to delayed deafness. "If a child cannot speak even when he is 2-3 years old, parents should not think that it is simply because they are late in speaking. They should go to the otolaryngology department to find out as soon as possible.

If a child has hearing loss, he or she must undergo a comprehensive hearing test as soon as possible. Use professional hearing aids to choose the hearing aid equipment that suits you, check as soon as possible, intervene as soon as possible, and treat as early as possible. Especially for children under 2 years old, during the critical period of learning language, they cannotA moment of carelessness leaves a lifelong regret.


Experts point out that the treatment and rehabilitation of children’s deafness must start early: early detection and diagnosis, early fitting of hearing aids, and early auditory and language training.


Early detection mainly means that parents should closely observe the baby’s auditory and speech behavior. For example, children within 3 months of age should blink or react to a sudden strong sound. Jitter response: at 4 months old, he can turn his head in the direction of the sound source, at 6 months old, he can rotate his head to look for interesting sound-producing objects around him, at 9 months old, he starts to learn to call mom and dad, and at 1 year old, he can stand alone. If parents find any abnormal behavior in their baby, they should go to the hospital for ear examination immediately. Determine the type of deafness based on the child's symptoms. If the diagnosis is sensorineural deafness, the child should be equipped with hearing aids and ear molds immediately, and auditory and speech training should be carried out as soon as possible. It should be emphasized that you cannot just buy a hearing aid in a store and use it. It should be fitted in a hospital or a specialized audiology institution. The principle is similar to the optometry of glasses.
