Hearing, quietly to

When we are around the sound used, do you know, some of the sound, you may unknowingly bring injury to the child\'s hearing, but we were not aware of?


Carefully listen to the voices around, perhaps you have used earlier, and didn\'t feel any discomfort. Do you know, in all voices, not all species are \"acoustic ear\", where noise is that we should keep away from but it is difficult to completely avoid. And relative to adults, children are more vulnerable to noise damage, bringing damage to hearing.


Environmentalists have noise in the environment we live in is divided into two categories: a lead to panic, while another may have devastating consequences. People living in the city, inevitably will be surrounded by all kinds of noise, with the passage of time, unknowingly waned under listening in noise. Particularly children, they are precisely the group most vulnerable to noise pollution caused by hearing diseases and often is, without any painful situation to make their hearing gradually waned.


High decibel sound is how to damage children\'s hearing it? Main noise excessive stimulation the children in the inner ear is small but very sophisticated \"induction receiver\". Children usually have 15,000 to 20,000 in the cochlea of such \"induction receiver\". Once they are injured, they have will no longer be able to send sound to the brain.


Due to the high volume of noise-induced hearing loss is permanent injury. Although hearing aids can help children hear sound, but, like myopia spectacles cannot cure as vision, hearing AIDS cannot fundamentally cure for hearing loss.


The first time, see hearing impairment


Experts believe that after the birth of the early years is an important period of their comprehensive development, if the hearing will cause serious obstacles to learning various skills, especially in the initial stages of his childhood. If a child\'s hearing had waned but later were found, then the critical period of development of listening and speaking is missed. In other words, because the sound cannot be transmitted through the ear to stimulate the brain\'s auditory control center, so the children\'s listening and speaking skills should have been no progress during the period of rapid development. Thus, also affected children and human development of communication skills and emotional development, studies on such children, also affects children\'s learning achievement.


It is unfortunate, the children of auditory disease was often ignored. Wait until you notice your child\'s hearing when there is a significant problem, your children are likely to have missed a lot of time to language learning and other important skills. So, parents should be nuanced to observation. In addition, here are some symptoms of a child after hearing, hoping to help parents keep their children in the hearing are normal in the period.


Neonatal: distance children clap 20~50 centimeters, he had no response, or did not quiet down after he heard your voice.

5: the child cannot be simple exchange with others, or difficult to understand what he said.


After school: for the child during the period, their performance of the hearing are: regular casual, spirit of undisciplined, attention is not focused, capacity is lower than the same period of the child, or frequent colds or ear pain.
