Calculations on a Model of the Vocal Tract for Vowel /i/ (Meat) and on the Larynx

As a sequel to experiments on the transmission of the vocal cavities, calculations on a model of the vocal tract for the vowel /i/ (meat) are performed to determine the magnitude of the impedances along the vocal tract and the relative contribution of radiation, friction, and coupled vibrations of the cavity walls to the total damping. Calculations also are made to estimate the impedances of the different parts of the larynx. From these calculations the effects of the coupling of the vocal cavities upon the larynx can be understood. Finally an old singing‐pedagogical problem concerning the resonances in the head is discussed.
