In order to be able to obtain the normative range of mean airflow rate (U), fundamental frequency of phonation (Fo) and voice intensity (I) during habitual phonation, a tremendous number of subjects of different sexes and varying age groups should be investigated. This is not an easy task for a single investigator or a single institution. The purpose of this paper is (1) to report the results from a limited number of subjects, (2) to show an example of statistical treatments, and (3) to document our data for other investigators who want to make use of them. The distribution pattern of the values of each parameter was examined with the use of stem-and-leaf display, box and whisker plots, mids, and 25% pseudo spread. Outside values were determined by means of Smirnoff test. The logarithmic and the square root transformation were attempted for U and Fo. The average and critical region of U were 156 cm3/sec and 99-246 cm3/sec for males and 158cm3/sec and 96-260cm3/sec for females. The average and critical region of Fo were 121Hz and 85-164Hz for males and 238Hz and 205-277Hz for females. For I, the average and critical region were 72dB and 60-84dB for males and 69dB and 62-77dB for females.
