Resonance Tube Phonation in Water—the Effect of Tube Diameter and Water Depth on Back Pressure and Bubble Characteristics at Different Airflows

Resonance tube phonation with tube end in water is a voice therapy method in which the patient phonates through a glass tube, keeping the free end of the tube submerged in water, creating bubbles. The purpose of this experimental study was to determine flow-pressure relationship, flow thresholds between bubble types, and bubble frequency as a function of flow and back volume.
