Out of the large number of congenital problems for which babies can be tested, the most common is abnormal hearing. There are two to four babies per 1,000 who will enter this world with a significant hearing impairment and this is why the condition is 20 times more frequent than phenylketonuria, a metabolic problem for which new-borns are routinely screened. In this case, the average age at which a serious hearing impairment is diagnosed is estimated to have a range from 14 months to 2 1/2 years. It is really not early enough even though it sounds like it. In the past, a lot of people took babies for granted and so they failed to accept the fact that even though they were only a few weeks old their brains were already developing the capacity for language and this was said by the director of the National Institute on Deafness and other Communication Disorders in Bethesda, Maryland. In terms of babies losing a great opportunity to learn language, this can happen if they receive no language input during a critical window of time, in this case a time that stretches back to birth. Early detection can allow a child to have a good chance of communicating normally, either in sign or spoken language by the time he or she begins school, but with late detection and intervention, what follows is a long, dreary game of catching up ahead. According to a professor at the University of Colorado in Boulder and lead author of the studies, if a child's problem is discovered late then there can still be hope but the situation will be harder. This is the reason why there are a lot of hearing advocates who want across the board screening for hearing problems in new-borns. The director of government relations for the American Speech Language Hearing Association, a professional group that advocates early screening said that infant screening is extremely important, given the baby boom let surge that the US is experiencing right now. Enacting legislation for universal new-born screening programs today are several states. What is serves to do is to test the hearing of an adult. When it comes to this, the people are put in booths by the audiologists and they should press buttons and parrot back phrases in response to the sounds they hear. Here, it is completely different to test the hearing of a baby. Taking an odd property of the ears that has been discovered and appreciated only in the past few decades into consideration, a baby's ears can do the talking. Other than receive sounds, the ears can also emit sounds. What sharpens our ability to hear is the source for these sounds which are the outer hair cells in our ears as they move around in response to noises. In this case, the movements cause the eardrum to vibrate and this sends noises back out into the world. What the ears do is make low level noises when exposed to sound but human cannot hear these. Considering such noises, these are loud enough for instruments to detect. The sounds aren't generated, and that is the essence of screening for hearing problems in new-borns. The procedure where a click of sound is sent into a baby's ear and then a little microphone detects any sound coming out only needs a few minutes for the technicians to complete. With this test, you will be able to detect anything from mild to profound hearing loss.
