Newly deaf children are predominantly congenitally deaf. Therefore, newborn hearing screening should only become more common. Currently, hearing impairment is one of the four major disorders screened for in newborns. The problem of congenital deafness is getting more and more attention from hospitals, and since 2003, it is required that all newborns be screened for hearing impairment. According to the requirements of newborn hearing screening, hearing screening is initially screened once at about 3 days of life and those who fail are rescreened within 42 days of birth. If the child still does not pass the screening, he or she will be re-screened once at 3 months of age. If the child is finally diagnosed with congenital hearing loss, then intervention and rehabilitation should be provided within 4 months of birth. In addition to congenital deafness, hearing can be affected by many factors during development, such as acute infectious diseases, ototoxic medications, otitis media and noise, all of which are “acquired factors” that can cause hearing loss in children. (Whether congenital or acquired deafness, 80% of them are neurological deafness, which cannot be cured with the current medical condition, so only hearing compensation can be done – hearing aids or cochlear implant surgery.) According to statistics, there are nearly 2.4 million deaf children under 7 years old with hearing impairment in Guangdong Province. Experts believe that if early detection and intervention can be made, deaf children can be fitted with hearing aids from the age of 6 months and have effective rehabilitation training, and deaf children can live and study like normal children. However, most parents of children with deafness expect to have their children’s ears cured without hearing aids. Many parents cannot accept the fact that their child wears hearing aids, and the difficulty in rehabilitation lies in this resistance. Hearing aids are like a loudspeaker. For children with hearing loss, if they can get hearing compensation through hearing aids, they will be able to hear people and communicate with them, and they will not lose their language function. Therefore, parents should change their mindset. If they can wear glasses for myopia, why can’t they wear hearing aids for hearing loss? After a hearing-impaired child is given a hearing aid or cochlear implant, he or she should also have the necessary auditory and language training. Because before the hearing aid or cochlear implant, the child is unable to hear or cannot hear well, and the natural ability to speak is affected. Therefore, parents should also cultivate their hearing-impaired children’s interest in sound and language, give them musical stimulation, and conduct the necessary auditory training so that they feel they are living in a world of sound and can learn language only when they hear sound. Reactions to sound at different times Sudden sounds at birth have a surprise reflex; sudden sounds close the eyelids tightly; sudden sounds at bedtime open the eyelids. 1 month Sudden sound when sleeping will awaken or cry; when crying or moving, talking to him/her will stop crying or moving; when calling him/her close or ringing the bell, will turn his/her face slowly. At 2 months of age, he/she will move his/her arms and legs when he/she suddenly makes a sharp sound while sleeping; he/she will open his/her eyes when he/she encounters noises, sneezes, bells or vacuum cleaners while sleeping; he/she will make a happy “ah” or “oh” sound when he/she is called. At 3 months of age, the child will open his or her eyelids or move his or her fingers when sleeping with a sudden sound, basically without the whole body surprise reflex; he or she will respond to the sound of a tape recorder, the sound of a TV switch or an advertisement (turning his or her face toward the sound source); he or she will show unease, joy or disgust at the sound of roaring, intimacy, singing, music, etc. Note: Hearing impairment should be considered first if sudden or peculiar sounds do not get the child’s attention up to the age of 1. Hearing problems should also be considered first if the child is still non-verbal or can only pronounce simple sounds at the age of 2 to 3. Once you find or suspect that your child has a hearing problem, be sure to go to a hospital otology or rehabilitation facility for a hearing test as soon as possible.
