Hearing Loss
Considering the congenital problems for which babies can be tested, the most common is abnormal hearing. Because there are two to four babies per 1,000 who enter this world with a significant hearing impairment, this is a condition which is 20 times more frequent than phenylketonuria, a metabolic problem for which new-borns are routinely screened. Usually ranging from 14 months to 2 1/2 years are the estimates for the average age at which a serious hearing impairment is diagnosed.
This may sound early enough but it's not. The director of the National Institute on Deafness and other Communication Disorders in Bethesda, Maryland said that in the past, we haven't really appreciated that even when only weeks old babies were just lying there, their brains were already developing the capacity for language. Babies can lose a great opportunity to learn language if they receive no language input during a critical window of time, in this case a time that stretches back to birth. With early detection comes a good chance of communicating normally, either in sign or spoken language by the time he or she begins school, but if there is a case of late detection and intervention, a child can expect a long, dreary game of catching up ahead. Even if a child's problem is discovered late, there is still hope although it will be more of a challenge according to a professor at the University of Colorado in Boulder and lead author of the studies. This is precisely why hearing advocates have been pressing for across the board screening for hearing problems in new-borns.
Highly necessary is infant screening given the baby boom let surge that the US is experiencing right now the director of government relations for the American Speech Language Hearing Association, a professional group that advocates early screening, said. Nowadays, several states have already enacted legislation for universal new-born screening programs. What it is for is to test the hearing of an adult. When people are placed in booths by the audiologists, they should press buttons and parrot back phrases in response to the sounds they hear. This is not the case when the hearing of a baby is being tested.
Because of an odd property of the ears that has been discovered and appreciated only in the past few decades, it is possible for a baby's ears can do the talking. What the ears can do is receive as well as emit sounds. In response to noises, the source of these sounds which are the outer hair cells in our ears actually cause our ability to hear to be sharpened. When it comes to this, 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. In terms of these noises, they are loud enough for instruments to detect. Here, the essence of screening for hearing problems in new-borns is having sounds that are not generated. The technicians only need a few minutes to complete this process where a click of sound is sent into a baby's ear and then a little microphone detects any sound coming out. You can find anything from mild to profound hearing loss when it comes to a test like this.
