Abstract
The threshold of hearing was measured on 1521 random samples of Japanese and the results were analyzed according to the age and sex. The hearing sensitivity decreased with increasing age accerelatively, specifically in high tone area and in advanced age group. Sex difference exists. Men are more affected than the women, but it was only slight degree, in high tone area and in older age group. The results of the present study was, as a rule, almost the same as previous one appeared in the literature. Accordingly, the results obtained is considered to be the standard of “the age effect on hearing of Japanese”.
