The Low-Hilger Audiometer was used to describe the vocal waves of the Japanese vowels in this study. The subjects of this experiment are seven males among the assistants and students of the psychological laboratory of the Doshisha University and four females. They were demanded to pronounce A ε i σ m of Japanese vowels in their ordinary speaking tones and these were recorded. Then the male subjects were demanded to pronounce the same vowels in different tones of c, e and g and the female subjects were demanded to pronounce in a', c' and e'. These vocal waves were analysed by the Fourier harmonic analysis on the 24-ordinate scheme. Acoustic Spectrums were made by the results of these analyses. The frequency of the maximum resonance, that is, the pitch of the characteristic frequency region was estimated by connecting the highest points of each spectrum. These frequencies of the maximum resonance of each vowel were summed up and thus the characteristic frequency bands of the Japanese vowels were decided in the following.
