1. Audiometric data for school children.The author performed a screening test using pure tone audiometer on 1.584 school children, the first graders to the sixth graders, in Nagasaki City, among whom 508 cases (32.1%) were suspected at the first test and 167 cases (10.5%) were suspected at the second test as having hearing difficulty.These 167 cases were tested again for air-and bone conduction threshould, and 116 cases (69.5%) were confirmed of their hearing difficulty and the remainder (51 cases, 30.5%) revealed no hearing loss, that is to say the latter were screened under suspicion of deafness in the absence of deafnees.More than 35 cases (2.5%) of children who passed the both screening tests were found to have hearing difficulty after having further inquiry and audiometry.In other words, they were not dected their deafness in spite of their hearing difficulty.The auther recommend a new standard of school audiometry, in which those who have more than two 20db or severe hearing loss in two or more frequencies among eight frequencies (125 to 8, 000cps) and those who have one or two hearing loss of 25db or more at 4, 000 and 8, 000cps.2. Study on the error of screening test.To infer the grade of error of the screening test, the author performed two screening tests and air-and bone conduction threshold test on 283 school children the first graders to the sixth graders of another school).The finding were as follows:Therefore, the author recommends a method to test the air-and bone conduction threshold of the children screened at the second screening test, to avoid the error of over-and under-screening.3. Study on the reliability of the response at the screening test.The author investigated the reliability of response at the screening test in 283 cases.The accuracy of the response at the second screening test was improved by 6.7% (from 86.7% to 93.4%) as compared with that at the first screening test.There isno marked difference of the accuracy of the response among the school graders.The accuracy of the response in lower school graders is somewhat better than in higher school graders, so that the screening test can be performed succesfully on the younger school children.
