Have Your Infant’s Hearing Tested in a Hospital
May 4, 2010 by admin
Statistics indicate that every year, in the U.S. alone about 12,000 babies have permanent hearing loss. Of every 1,000 babies born, three have one or the other type of hearing loss You will gain a deeper understanding about free hearing test Wollongong by checking out that resource.
Hearing loss cases are of different types with some people being able to hear everything except the very soft sounds to others who cannot hear anything at all. It is quite a routine matter to provide some treatment, in conjunction with hearing aids, to children suffering from hearing loss.
In the most extreme cases, cochlear implants remain the only option. Cochlear implants send signals directly to the auditory nerve even when a damaged part of the ear is unable to respond even to amplified sound coming from hearing aids. Complete restoration of hearing is still not possible with any of these devices.
To detect hearing problems in babies, it is a good idea to screen them as soon as possible. The first few months of a baby?s life can be very critical in developing language skills and hence the chosen therapies need to be started within the first six months.

Screening of newly born babies for hearing loss is now possible immediately after birth. The newly introduced procedures ensure that if hearing loss is ascertained in the first six months from birth, the language development proceeds almost normally.
22 to 26 months is about the age at which hearing loss gets detected in children. Quite often, hearing problems do not get detected till they manifest themselves as either speech related issues or language development problems.
Hearing problems can now be detected, using a new procedure, before newborns leave the hospital.
Otacoustic Emissions are able to conclusively establish a newborn?s hearing ability. A soft probe is used for delivering sounds into the ear canal. An echo like sound created by the inner ear is picked up by a microphone which is embedded in the same probe. This procedure lasts about 10 seconds for each ear, while any conventional procedure would have taken 10 minutes.
The Auditory Brainstem Response test is required to be administered to babies who fail the OAE. The ABR test measures the auditory nerve?s responses to sounds delivered to the baby?s ears by a disposable earphone, by three throwaway electrodes placed on the baby?s head and shoulders.
Each ear takes a mere 15 minutes to be screened.
Although the duration of these tests is small, the requirement is that babies must be asleep. Quite often, hearing problems do not get detected till the age of 2 years when they manifest themselves as either speech related issues or language development problems.
Screening all babies is a sure way to ensure none of them has a problem later on in life. This is going to prove very beneficial for the language development of children and also for their entire lives.
In the less likely event of a baby failing both these tests, an audiologist needs to conduct diagnostic testing. This happens in about two percent of the cases.
Hearing loss of infants as small as two months of age can now be overcome by providing them amplification equipment. Help being available early, can ensure normal development of these children.
