Effects of Length and Depth of Vibration of the Vocal Folds on the Relationship between Transglottal Pressure and Fundamental Frequency of Phonation in Canine Larynges

Abstract

The relationship between fundamental frequency of phonation (Fo) and the change in Fo per unit change of transglottal pressure (dF/dP) was investigated in 3 excised canine larynges. The effects of the length and depth of vocal fold vibration on the relationship between dF/dP and Fo were evaluated. A positive correlation between dF/dP and Fo was observed when an increase in Fo was accompanied by a decrease in the depth of vibration while the length of vibration reached a plateau. Although a negative correlation between dF/dP and Fo was observed in only 1 case, this relationship seemed relevant to the length of vibration. These results help to clarify the adjustments of length and depth of vibration involved in regulating Fo.
