Abstract
It seems that auditory training of children who has 80dB hearing loss is very difficult. But in order to habilitate their language and speech, it is a distinctly advantageous approach to use their residual hearing through hearing aid.
This study attempted to investigate how children who has 80dB hearing loss are able to hear sounds and discriminate speech sounds.
Five children who has flat type of hearing curve, a verage 80dB, congenital hearing loss were chosen as samples.
The summary in this study is as follows.
1) Although their score are very poor, they can discriminate simple speech sounds by using powerfully amplified hearing aids.
2) Their unaided and aided speech reception threshold shorned almost the same level with their unaided average and aided hearing loss for pure tone.
3) In dealing with discrimination for vowel sounds, discrimination score had the tendency to become worse in “a, o, i, u, e” order. They discriminate “u” sounds very hardly and did not discriminate “e” sounds at all.
4) Correct and effective hearing aid and volume control should be considered.
