Parameter analysis using swallowing sounds shows differences in bolus volume, bolus viscosity, sex, and age

Abstract Acoustic analysis of pharyngeal sounds during swallowing may capture physiological functions, providing a noninvasive method for early screening of swallowing decline. In this study, we examined changes in swallowing function across variations in bolus volume, bolus viscosity, sex, and age...
