[First results of a study for the standardization of the electroglottogram of the normal subject]

"Primary results of a study for the standardization of the electroglottogram in normal subjects". Using one sample of waveforms from 151 normal subjects, 79 females form 17 to 80 years of age and 72 males from 12 to 85, the waves were normalized in accordance with frequency and amplitude. Two Kinds of parameters were measured, a) morphological, consisting in the three temporal phases determined by the three main inflexions of the waveform, and b) global, obtained when the glottal cycle is divide through the horizontal line of the electrical "O" into a negative and a positive semi-wave. Statistical analysis shows significant variations in the morphological parameters according to sex, age and fundamental frequency of voice Fo, confirming their close correlation with the vibratory events in the glottis. No significant relations have been found between global parameters and sex, age and Fo, indicating a lack of correlation between the electrical "O" line of the electroglottogram and the vibratory events of the glottal cycle.
