A Study on the Principle of Sound Production in Human Whistling using Physical Models of the Human Vocal Tract

Principles of sound resonance in human whistling using physical models of human vocal tract

“…Because the shape of the mouth at the time of whistling is considered to be close to the mouth structure required for the pronunciation of the vowel /u/, Mori et al reported adjustments made to physical models to achieve this shape [5]. Following this approach, the vocal cord parts in the model used in this study were detached and various components (described below) were added.…”

“…Following this approach, the vocal cord parts in the model used in this study were detached and various components (described below) were added. By employing simplified models, Mori et al also demonstrated that the resonant frequency and mode in human whistling involve not only the Helmholtz resonance mode but also an air-column resonance mode [5].…”
