Swallowing acoustic characteristics
Splet02. jan. 2024 · Swallowing is a complex but brief action that propels a food bolus from the oral cavity to the esophagus while protecting the respiratory tract. This action involves 25 paired muscles of the mouth, pharynx, larynx, and esophagus, which must act in a coordinated manner during voluntary and reflex activation and inhibition sequences [ 1 ]. Spletacoustic characteristics. Results indicated increasing pha-ryngeal swallowing duration with increasing age, bolus viscosity, and bolus volume. In addition, an increased duration to peak intensity with increasing age was found in one of our two analyses, as well as with some of the more viscous versus less viscous boluses.
