Hearing impairment and schoolchildren
The two types of hearing loss
This is caused by problems in the outer or middle ear which prevent the sound from being ‘conducted’ to the inner ear and hearing nerves. The hearing may fluctuate and may affect one or both ears to varying degrees. Conductive problems generally affect the quantity (loudness only) of the sound that is heard. It is usually medically or surgically treatable.
A common cause of conductive loss in children is middle ear infections.
This type of hearing loss is due to a problem in the cochlea (the sensory part of the ear) or the hearing nerve (the neural part). It can be acquired or be present at birth. There is usually a loss of clarity as well as loudness i.e. the quality and the quantity of the sound is affected.
NOTE: It is possible to have both a conductive and a sensorineural hearing loss. This type of loss is called a mixed hearing loss.
Unilateral versus bilateral hearing loss
When there is a unilateral hearing loss
- Only one ear is affected
- It causes great difficulty in hearing in background noise.
- It makes localising the source of a sound very difficult (important for road safety).
When there is a bilateral hearing loss…
- Both ears are affected.
- Speech is heard at reduced loudness levels.
- Bilateral sensorineural hearing losses can cause the sounds to be distorted. Putting sounds together meaningfully can be a difficult task.
- Medical intervention is not usually possible and the loss is permanent.
- Hearing aids are frequently fitted to assist the child to hear, depending on the degree of hearing loss.
The following suggestions may help teachers overcome some of the difficulties that hearing impaired children typically experience in the classroom situation.
- Seat the hearing impaired student close to the teacher for the best sound reception and visual information. However, don't restrict them to only one location. Allow the student to move to a better listening position if they wish.
- Check the student has a clear view of the whole class for participation in group activities if possible.
- If one ear is better than the other, ensure the better ear is directed to class and teacher.
- Sit the student away from noisy areas.
It may be necessary to change the seating arrangements for particular activities.
- Ensure good lighting on your face. The glare of strong lighting (such as a window) behind the speaker makes lip reading difficult.
- Speak clearly but naturally; exaggeration or shouting can make it more difficult for the child to understand speech.
- Try to remain in one area while talking. It's difficult to lip read someone moving about a lot.
- Don't talk while your back is turned to the child (e.g. writing on blackboard).
- Try to use as many visual aids as possible.
- When reading aloud, try not to let the book cover your face.
Make sure the hearing impaired student is attending (not just listening) when you begin new work, when you ask a question, or when you give out a job.
Check that the student has understood your instructions, e.g. by asking them to repeat what was just said.
It may be helpful to have a responsible peer share their notes with the hearing impaired student and to fill the student in if some direction or discussion is missed.
People with a hearing impairment cannot block out background noise as people with normal hearing can.
Take steps to reduce the amount of noise in the classroom, such as minimising movement around the class and encouraging the students to be quiet during important teaching times. Try to seat the student away from noise (e.g. a noisy child or open window).
Reading ahead on a topic or some other form of preparation will allow the hearing impaired allow the hearing impaired student to “tune into” the subject and follow discussion more easily.
If the student did not understand, try saying the same thing another way. Encourage the student to admit when they don’t understand, as many will be reluctant to do so.
Don't expect continuous attention on the hearing impaired student’s part. Remember, they may have to work harder to listen than their normal hearing peers and the concentration required to hear can be very tiring.
Watch the socialisation of the hearing impaired student with their peers. Encourage a positive acceptance of the student by other children.
Hearing aid care
Support the use of hearing aids or other listening systems that may be used. Routinely check they are being worn as recommended and that they are working correctly.
Australian Hearing support for teachers
If the child wears a hearing aid, they will be under the care of an Australian Hearing Audiologist who is there to offer support and advice to teachers. The Audiologist can help you understand the child’s hearing loss and aided ability, explain how to best communicate with the student, discuss hearing aids and other devices which help them hear, provide in-service training and informative reports.
If you would like advice or more information, call 131 797 to be connected to your nearest Australian Hearing centre.
