The screening errorwas 1.55% and 1.91% in each side.2) Streptomycin deafness: One thousand and forty-five persons were examined using a pure toneof 8000 cps at 15db. without error. It was found in this case that the test of one ear was sufficientto screen the streptomycin deafness.3) School children deafness: Five thousand three hundred and eighty-two ears were examinedusing two pure tones of 1000 and 4000 cps at 20 db. respectively. In each case, the reason whyabove mentioned value of cps and intensity used in the test was discussed and results werecompared with that of the audiometry
