1) We are not only using hearing aids to hard of hearing children but also to the severely deaf children in the early stage.
2) As a rule, we use a single hearing aid in one ear, but for the children whose hearing impairment is not determined in either of the right or left ear an ear-piece in each ear connected to a hearing aid with Y-code is preferable.
3) As it is difficult for us to determine the suitable volume after studying the research done by Dr. Ogura and others we determined that 70phon input is the optimum volume to bring remarkable reaction.
4) From the inquiries of using hearing-aid of 32 subjects, the following findings were obtained.
a) Within a month 70% of children could tolerate wearing hearing aid, and within three months, the effect of hearing aid could be obtained.
b) In profoundly acoustically retarded children, hearing aids are effective in the raising of the intensity of their voice.
5) In the future, the application of the EEG, play audiometry, speech audiometry and characteristic test of hearing aids is necessary for the investigation of the optimum volume.
