The fundamental frequency (F0) and sound pressure level (SPL) of voice were measured in 1,563 dysphonia patients of varying etiologic diseases. The measured values were compared with the values obtained from normal control subjects. The results were summarized as follows : (1) In most disease groups, the highest F0 was low and the F0 range was decreased. (2) In most disease groups, the SPL for the loudest phonation was reduced and the SPL range was small. (3) The F0 level for habitual phonation was low in acute laryngitis and Reinke's edema and it was high in sulcus vocalis, carcinoma and mutational dysphonia in males, whereas, in females, the F0 level for habitual phonation was low in many disease groups. (4) Similar tendencies were noted with the lowest F0. (5) The SPL for habitual phonation was within the normal range in almost all disease groups. (6) F0 and SPL presented low but significant correlation to the degree of the lesion in the cases with polyp and carcinoma. (7) The effect of treatment was reflected on F0 and/or SPL in many disease groups.
