Hearing tests for children & newborns

Everything you need to know about hearing tests for children

In everyday life, parents can look out for the following things that your child should be experiencing as they develop. Keep in mind, however, that every child has its own pace of development.

  • With four to six weeks loud noises frighten your baby and they can be soothed by your reassuring words.
  • By the third month, babies begin to babble and laugh, and keep their heads moving toward the smells in their environment.
  • By the sixth month, babies are listening to heard sounds.
  • With the seventh and eighth month, babies react to music and test different sounds and pitches.
  • With ten to twelve months children understand bans and react when you approach them from close. Children who hear nothing, fall silent.
  • A child of two to three years obeys instructions and speaks first sentences.

When you see that your child is not reacting to auditory stimulus, it’s best to sign up them up for a hearing test. Hearing loss in children can be detected in delayed responses or the absence of a response to nearby sounds. Although children do develop at varying paces, it is important to keep watch of your child once you notice the non-responsiveness.

Hearing tests for newborns

Since 2009, newborns have legal entitlement to a hearing test. This is how an existing deafness can be recognized by the doctor as soon as possible. Deafness is one of the most common congenital disorders. Two to three out of 1,000 newborns have a hearing impairment. The hearing test in newborns is called hearing screening and is completely painless for your child and only takes a few minutes.

 

For the hearing test in a toddler, there are two methods:

1. Automated brain stem audiometry

In automated Hinrstammaudiometrie the reaction of the Gerhins is measured on the probe tone. To the forehead, the neck and the cheekbones are covered with small electrons and the child gets a kind of headphones put on the clicking sounds are sent to the inner ear. If a response is measurable, the middle ear, cochlea, auditory nerve and the lower part of the auditory pathway are functional. If the transmission of the siginal disturbed, this indicates a limited hearing.

Optimal conditions for this method are:

  • Calm environment
  • The child sleeps during the examination

2. Otoacoustic emissions

Otoacoustic emission measures the sound emissions of the outer hair cells of the inner ear via a very sensitive microphone. Here, the function of the cochlea can be tested specifically. The ear is offered a special tone. When the ear is healthy, the cell reacts with vibrations. If the signal remains off or is only weak, the sound pickup in the cochlea may be disturbed. If the result is conspicuous, it does not automatically mean that the baby does not hear anything. For example, liquids may be in the ear or background noise may affect the result. 

Optimal conditions for this method are:

  • while the toddler is sleeping
  • if possible, only measure from the 3rd day of life
  • no noise, no suckingc
  • carefully insert the probe into the ear canal, paying attention to the sealing

Hearing test for Children

The auditory test of the child is not painful and is made in the form of games. This test will help determine the child's hearing threshold and determine the source of the disability.

This auditory test is done in several stages:

  • Inspection of the ear canal of the child: it can detect the presence of any wounds or infections in the ear of the child.
  • The objective test: this test assesses the hearing sensitivity of your child. It allows to know if the elements of the ear whose eardrum and the cochlea correctly receive the sounds transmitted to the ear.
  • Audiometry measures the threshold of hearing. The child will be exposed to different frequencies and intensities of sound to determine the smallest sounds perceived on each ear. The results will then be translated by a curve called an audiogram.
  • The audiogram of the child can be performed by several health professionals for complimentary purposes. The ENT doctor practices it to find out if there is a hearing loss. The Audiologist/ Hearing care professional does this to determine very precisely the audiometric profile that will be used to adjust the hearing instruments. This is why the Audiologist/ Hearing care professional will systematically perform a new measurement, even if it has already been done by your ENT doctor.

If a hearing loss is detected, medical or technological treatment will be recommended by the ENT doctor.
