This paper illustrate residual hearing and socio-medical background on the hearing impaired children, 207 comming to Deaf School. attached to Hankuk Social Work College, Taegu, Korea.

The survey was performed through interview with their parents and testing by diagnostic audiometer (TRIO, AS 105 type) at soundproof room from March 10, to November 28, 1973.

The results obtained were as follows.

1) The attendance rate of the compulsory primary school was markedly lower tendency in female than male according to directly proportional to prevalence rate of deafness among them. If was showed the deeper gap in the more superior school (middle and high school).

2) Who entered at the suitable age to each school (six years old to primary school, 12 years to middle and 15 years to high) was 11. 3%. And who were enrolled in school age to each school (611 years for primary. 12-14 years for middle and 15-17 years for high) was 45.(9% (43.7% in male, 50.00/, in female).

3) As causative disease, congenital case, were 23.6% included of 13.5% of heredity and 10.1% of troubles during pregnancy; the total acquired cases were 479%, it was classified as 11.6% of convulsion from any other diseases, 7. 7% of measles, 7. 7 % of other febrile diseases, 3. 4% of drug (the most of streptomycin) intoxication, 2.4% of meningitis, 1. 5% of epidemic encephalitis and 31.3% of other diseases; and unknown cases were 28.5%.

4) 31.4% of who included congenital cases lost their hearing within six months -old, 11_ 6% in 611 11 months. 9. 7 % in.1-2 years old and 14.0% in 2-3years old, Consequently we obtained that the most cases 90. 0% were lost. their hearing within 3 years after birth.

5) According to qualities of hearing losses the most of cases were perceptive, 197(97.5%), only two cases were conductive, and eight cases were mixed.

6) The status of residual hearing according to average grade of hearing loss, B(= a+2b+c as table 13) were as follows. Two cases were normal (one was mute and another was severe speach disorder). Ten cases, moderate. Moderately severe cases were 40 (19.3%). Severe cases, 38(18.4%). Scale out, profound cases, 48 (23.3%). And impossible testing cases because that were infantile or had some mental disorder were 69 (33.3%).

7) The using rate of hearing aides was only 12.0%. Among them who had some more residual hearing and could showed hearing effect with hearing aide have used more many proportionary but who were difficult to expect that effect were rare.
