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. Children who suffer from hearing loss are advised some therapy and could also need to wear hearing aids.

In extreme cases, doctors recommend what is known as cochlear implants. The biggest advantage of cochlear implants is that they act upon the auditory nerve when any damaged part of the ear fails to respond to amplified sound from hearing aids. Complete restoration of hearing is still not possible with any of these devices.

Doctors will always recommend that babies be screened as soon as possible after birth. Hearing therapy started within the first six months gives babies their best chance to develop their language skills. This site teaches you about free hearing test Taree.

A new procedure is proving very helpful in detecting hearing loss in babies immediately after birth. Modern procedures ensure that language development in newborn babies can proceed normally if hearing loss is detected within the first six months.

In a vast multitude of cases, hearing loss is detected in children only after they are 22 to 26 months old. It is a common occurrence that parents and caregivers first detect speech or language development problems which are only a symptom, the root cause being hearing problems.

Before newborn babies are discharged from the hospital, a new procedure allows screening them for hearing loss.

Otacoustic Emissions are being used increasingly to determine how well a baby is able to hear. Sounds are delivered into the ear canal by a soft probe. A microphone which is placed in the same probe receives the echo which the inner produces. What used to take 10 minutes to screen each using a conventional procedure now takes merely 10 seconds.

Babies who fail the OAE test are administered the Auditory Brainstem Response test. On the baby?s head and shoulders are placed three electrodes to measure the auditory nerve?s responses to controlled sounds delivered through a disposable earphone as per the norms of the ABR test.

Screening of each ear is a simple 15 minute task.

When these tests are run, the babies must be sleeping. Speech and language development problems, noticed around the age of 2 years, happen to be the first symptoms that lead to the detection of hearing defects.

To eliminate the chance of babies having problems after growing up, it is best to screen all of them. Children will be able to develop their language skills better and also lead near normal lives forever.

Only those babies who fail both these tests are referred to an audiologist for diagnostic testing. About two percent of the babies have to undergo diagnostic testing.

Hearing loss of infants as small as two months of age can now be overcome by providing them amplification equipment. If these children get help very early on in their lives, they have a good chance of leading a normal life.
