Hearing impairment
Signs
* limited attention span * daydreaming * slowness of responses * breathing through the mouth * Irritability. Four categories of hearing impairment are generally used: mild, moderate, severe and profound.
Some pupils with a significant loss communicate through sign language such as British Sign Language (BSL) instead of, or as well as, speech.
Conductive deafness
This is when sound cannot pass efficiently through the outer and middle ear to the cochlea and auditory nerve. The most common type of conductive deafness in children is caused by ‘glue ear’. Glue ear (or otitis media) affects about one in five children at any time.
Sensori-neural (or nerve) deafness
This is when there is a fault in the inner ear (most often because the hair cells in the cochlea are not working properly) or in the auditory (hearing) nerve. Sensori-neural deafness is permanent.
Children who have a sensori-neural deafness can also have a conductive deafness such as glue ear. This is known as mixed deafness.
Presenting difficulties
There are some common signs that might indicate a hearing loss: - * The child does not respond when called. * There is a delay in learning to speak. * There is a lack of clarity in speech. * Unstressed words in speech may be missed or misinterpreted. * The child watches faces/lips intently. * The child is reluctant to speak freely. * The child displays inappropriate behaviour. * There are difficulties in listening and attending to speech. * Constantly asking for repetition. * Failure to follow instructions straight away or misunderstanding/ignoring instructions. * Requiring repeated explanations. * Watches what others are doing before doing it themselves. * Continues with an activity when the rest of the class has stopped. * Inattentive and daydreaming. * Doesn’t pick up information from overheard conversations. *
