• The laryngeal primary tone is modified by the resonance cavity (mouth, nose, throat) and becomes the individual voice which we can hear.A method of the qualitative research of the primary tone was devised.The differences of the spectrum pattern (Section of Sona-Graph) between the vowel "a" and whispered voice "a" were measured and this difference was regarded as spectrum pattern of primary tone.The spectrum pattern of various qualities of voice (loud and natural voice, male and female voice) was examined, In loud and male voices, spectrum pattern had many overtone than the natural and female voices, and individual over tones of the former were taller than the latter.The spectrum pattern of the primary tone which was taken from the patient by probe-tube microphone during surgery and spectrum pattern of the former method were compared.A general similarity was seen.
