Conditioned orientation reflex audiometry was reported by T. Suzuki and Y. Ogiba in 1960, which was applicable to the children ranging in age from 1 to 3.years for pure tone audiometry. However, we have still some problems in children with big difference acuity of hearing between both ears.The auther studied to prove these problems. Difference between the binaural summation threshold measured by conditioned orientation reflex audiometry and the threshold of each ear measured by play audiometry was investigated in 82 children, for whom both audiometries could be successfully per. formed. The difference over 20db between the both thresholds was frequently observed at all frequencies tested. Therefore, the correlations between the threshold measured by conditioned orientation reflex audiometry and the each threshold of the better ear or the worse ear by play audiometry were separately investigated. Consequently the correlation was more significant in the worse ears than in the better ears, as the significance was 1%.
