The authors asserted the importance of auditory screening test for school children not only in the medical, but also in the educational point of view and presented a new method of screening test.Sixty five thousand seven hundred and eighty nine primary and middle school children were tested by this method in 1979.The method are as follows:When a child fails to respond to 20dB (JIS) pure tone in 1kHz or 4kHz, he is tested immediately at 40dB level. Thus one can obtain more information as to the nature and grade of hearing impairment of the child than the usual screening test.The authors classified the hearing status into No. 0 (normal) to No. 8 types. According to this classification the hearing of both ears of the child is described in 2 numbers for example 2-5. This method may be very useful for statistical purpose as well as for individual care of the hearing impaired school children.
