GOTO AND YAMADA devised a method of hearing test in which they selected a tone 20 db. above the value of threshold of hearing as a test tone and calibrated it from 0 to 90 db. Hearing test is made by obtaining the ra-nge of hearing of this test tone as broad or na-rrow as the case may be. They arrived at foll-owing conclusions: (1) A narrow range indicated changes in the organs of Corti,

(2) A normal range which was obtained by s-ubjecting a normal person to temporary des-fness for comaprison indicated 8th nerve involvements, changes in the endolymph or, changes in thd organs of Corti or the hear-ing center, and,

(3) A broad range indicated changes in the hearing center.
