School screening program was administered to the children under school-age.
The subjects were 580 children aged from three to five, and 288 school-age children in the first and fourth grades were examined as control. The 20dB (JIS-1956) screening levels at 1, 000Hz and 4, 000Hz were used. Those who failed the first test were retested by the same procedure, and those failed the second test were tested with standard audiometry. The hearing-impaired children were examined medically by an ENT docter.
The following results were obtained.
1. Incidences, types and degrees of hearing-impairment and ENT findings in the hearing impaired children under school-age were similar to those found in school children.
2. The percentages of normal hearing children who failed the screening tests were larger than those in the control group, and approximately one third of the children failed the second test were found to have normal hearing.
3. The test time for screening of each child was longer than those in the control group, and in three-year-old children the test time was twice as long as that in the first-grade children.
It was concluded from these results that school screening audiometry could be applicable for the children under school-age, though exercises how they response to test sounds before actual screening tests and the tests should be repeated more than three times.
