Hearing Impediments

In the case of abnormal hearing, it is the most common out of the congenital problems for which babies can be tested. Considering how two to four babies per 1,000 enter this world with a significant hearing impairment, the condition is actually 20 times more frequent than phenylketonuria, a metabolic problem for which new-borns are routinely screened. Estimates range from 14 months to 2 1/2 years when it comes to the average age at which a serious hearing impairment is diagnosed.

Even though this sounds early enough, it is 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. There are times when if they receive no language input during a critical window of time, in this case a time that stretches back to birth, babies lose a great opportunity to learn language. 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. As mentioned by a professor at the University of Colorado in Boulder and lead author of the studies, there will still be hope even if a child's problem is discovered late but it will be more challenging. What hearing advocates want is across the board screening for hearing problems in new-borns and this is the reason behind it.

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. There have been several states that already enacted legislation for universal new-born screening programs. Here, this makes it easy to test the hearing of an adult. When the audiologists place people in booths, they need to press buttons and parrot back phrases in response to the sounds they hear. It's another matter to test the hearing of a baby.

Luckily, a baby's ears can do the talking, due to an odd property of the ears that has been discovered and appreciated only in the past few decades. It is possible for the ears to both receive and emit sounds. Our ability to hear is sharpened as the outer hair cells in our ears which are the source for these sounds move around in response to noises. As a result, the movements vibrate the eardrum; sending noises back out into the world. This site teaches you about hearing loss test.

We do not have the ability to hear the low level noises made by the ears when exposed to sound. Here, these are loud enough for instruments to detect. In terms of sounds not being generated, this is the essence of screening for hearing problems in new-borns. Here, the technicians only need a few minutes to complete the process where a click of sound is sent into a baby's ear and then a little microphone detects any sound coming out. It is detecting anything from mild to profound hearing loss that is possible with this test.
