Abstract:
ObjectiveTo study the relation of phonation and respiration in normal subjects. MethodsUsing Aerophone Ⅱ Model 6800 and Visipitch 6097, vital capacity was recorded first , then the simultaneous phonation volume, maximum sustain phonation time,mean airflow rate,sound pressure level and average pitch were recorded in order to induce the relation of phonation and respiration in normal subjects. ResultsThere was a linear correlation between phonation volume and vital capacity. Maximum sustain phonation time varied with changes of mean airflow rate and phonation volume and mean airflow rate varied little in different subjects and had no relation with average pitch and sound intensity. ConclusionMaximum phonation time, the mean airflow rate and ratio of phonation volume to vital capacity can be used as indicator in clinical application.
