It is important that you keep an eye on the health of your baby, so he is not sick and do not have any complaint, it is best that you frequently check their ears, their language, their way of paying attention, what skills you have, what and not tell your pediatrician confidence to go and assess their health and correct in time any type of illness that may be too late.
The main causes of severe and profound childhood deafness are genetic (at least 50%), followed by the learned and bad training.
How do you detect?
As we have seen, is very important to evaluate any suspicions we have about our child may suffer some hearing impairment. This assessment is easier in the adult, just do a conventional audiometry in most cases.
However, in the young child, at least until 3, 4, 5 years, such tests are unreliable, or impossible to implement. The small baby can not consciously collaborate in the test, because of their immaturity and for failing to buy even the language.
There are only some hearing tests that basically consist of the issuance of sound stimuli and recording children’s responses to these stimuli (whether or conditioned reflex responses.)
* Newborn. With a whistle, bell, drum, etc. produces a noise or sound of short duration and strong intensity, the ear of the child. There must be a startle reflex response, (may cause the Moro reflex is an extension of the extremities accompanied by an arching of the back), and a change in the initial state of the child: he wakes up, leaves to mourn, or does not suck.
* Infant. With a toy that produce noise or sounds (a doll, a whistle, trumpet, etc..), Will produce different sounds of a certain intensity alternating the two ears of the child. The sound stimulus will cause a reflex of orientation toward the sound source, and conscious and look for certain movements with his eyes.
* From a year. Right and left the child is placed two dolls that move and emit a sound alternately. The child must turn his head to one side or another to find the source of the sound and see the doll in motion.
* From 3 years. You can perform conventional audiometry. Consult your trusted doctor.
In the common examinations which the doctor makes for healthy children are some of these tests. But he believes it is important that parents know to some extent how does the evolutionary development of the sense of hearing as well as some simple tests you can do at home to facilitate early diagnosis of such alterations.
