Hearing Loss At Children
The good hearing is vital for a child’s correct development because only at its presence he can learn to speak and to become a high-grade member of a society. But more often the hearing at the child happens lost from a birth. Now this lack can be corrected and is not a tragedy. If hearing loss is found out early enough and in time is corrected by modern means, speech of the kid will develop not worse at all, than at children with normal hearing.
Statistics shows, that problems with hearing are observed at one-two newborns from a thousand. Approximately a half from them is caused by the descended diseases. The base of others has been put during pre-natal development. Hearing of yet not born child can be adverse influenced by such factors, as disease of the pregnant woman by measles, toxoplasmosis, a syphilis etc., and also an influence of some medicines, alcohol and nicotine.
Proof loss of hearing can come in the course of delivery or after them: too long childbirth, oxygen insufficiency, application of strong antibiotics. There is a certain danger to lose hearing and at early children’s age. First, many of the inherited hearing disorder are shown not at once. Secondly, hearing loss can become one of complications after an infectious disease, thus the greatest danger is represented by meningitis, and also a scarlet fever, a measles and mumps.It is vital to find out loss of hearing at the child as soon as possible. The matter is that at each normally hearing child the first stage of development of speech is the period of passive perception when the child only listens, but does not speak. This obligatory period lasts for about 18 months, since a birth, and is called “the age of hearing”. If at the child the depressed hearing it cannot distinguish and remember separate elements of speech, and gradually absolutely ceases to react to it. Not used rests of the hearing can completely and disappear for ever. That it has not occurred, it is necessary to increase loudness of speech that the child could perceive it normally by means of a hearing aid. The earlier to make it, the better it is for a child. Today at the timely beginning of rehabilitation even children with deep loss of hearing have good chances to even to normal contemporaries.

All these modes are absolutely painless and harmless to health of the child.
