Approximately
one child in a thousand will be born with hearing difficulties in the UK every
year. Early diagnosis is very important. When
your baby is born, his/her hearing will be tested before you leave
hospital. This is part of the Newborn
Hearing Screening
Programme.
The
following may indicate a potential hearing difficulty:
- The
child may not respond when called
- Delay
in learning to speak
- Difficulties
in listening and attending to speech
- Speech
is unclear
- Possible
inappropriate behaviour or temper tantrums
- Watches
the face/lips intently
If
you are worried about your child’s hearing, do not hesitate to contact your
doctor who will be able to refer you to an audiologist. They will carry out some tests to establish
whether or not your child has a hearing loss.
There are two
main types of hearing difficulty or deafness:
1. Conductive deafness – sounds are unable to
pass through the outer and middle ear.
This is often caused by a build up of fluid in the middle ear known as
“glue ear”. This type of deafness can be
temporary and may be aided by the insertion of grommets to drain the fluid.
2. Sensori-neural deafness – due to damage or
loss of hair cells in the cochlea in the inner ear.
A child may
sometimes have a mixture of the above two forms of deafness.
A child may
be born deaf or become deaf following an illness such as meningitis. Sometimes a child may become deaf and the
cause is not known.
There are
different levels of deafness. They are
measured in decibels (dB). These are
usually classified as:
- Mild 20-40 dB
- Moderate 41-70 dB
- Severe 71-95 dB
- Profound 95+
If a child is
deaf in one ear it is known as unilateral deafness; in both ears, bilateral
deafness.
A speech and language therapist will help to assess the impact on speech, language and communication.
