Abstract : Pure tones, similar in frequency to fundamentals of voices, were heard by subjects at a constant intensity. A subject read a nonsense syllable after 10-sec. exposure to a tone. The frequency of the tone was then changed and after a 10-sec. exposure the subject read another syllable. This continued through 30 syllables. Each of 10 experimental frequencies was heard three times. The same vowel appeared in all of the syllables. Measurements of frequency and intensity of the read syllables were analyzed. Both vocal frequency and intensity increased as the frequency of the stimulus tone became higher. The procedure was repeated with the loudness level instead of the intensity of the stimulus tones held constant. The results were inconclusive. (Author)
