I am sure you are aware of hearing impairment …
Deafness means loss of hearing and it may be partial or total. Hearing impairment cannot be seen and hence its effects are not visible to others, so deaf suffers in silence. Unlike blindness, deafness often provokes ridicules rather than sympathy. A deaf person is so isolated from family and friends and greeted by unsympathetic attitude he/she is often depressed and needs psychological counselling.
The consequences for a child born with hearing loss are quite severe. It is well established that a child with hearing loss cannot develop speech and language abilities. This puts the child at a disadvantage in school, higher education, and limits future professional opportunities. The problem of the child deaf from the birth is quite different from that of the adult who has become completely deafened after school age or in adult life. The hard of hearing person whose deafness has developed slowly over the years is different again. But, for all of them, the handicap is the same – the handicap of the silent world, the difficulties of communicating with the hearing and speaking world.
