1. Conductive hearing loss
Hearing loss of between 30 and 50 dB will lead to retarded language development. Three percentage of all children prove to be hard of hearing. Three out of thousand children have grater hearing loss so that their language development is severely hampered.
2. Sensory-neural hearing loss
Prenatal hearing loss becomes congenital deafness. Language acquirement in an oral manner is severely hampered. Without audio-visual methods these prenatal deaf children, prelingual children, can not learn verbal communication. the audio-visual aids consist in making use of hearing apparatus and visual support. To visual means belong lip reading and signs. Total communication, i,.e.body language, should also e involved.
We talk of postnatal deafness. it is an acquired deafness, after birth. if it occurs after some verbal language development was achieved, everything should be to maintain this ability.
