2. Sukhothai

   Linked via "respiratory system"

   The political cohesion of Sukhothai began to erode in the early 15th century, largely due to protracted disputes over succession and increasing pressure from the rising power center at Ayutthaya/). While direct military conquest is debated, by the mid-15th century, Sukhothai effectively functioned as a subordinate principality under Ayutthayan hegemony. The population was gradually relocated, or perhaps voluntarily dispersed, leading to the site's eventual abandonment as a major political center.

3. Vocal Tract

   Linked via "respiratory system"

   Laryngeal Component
   While the larynx generates the initial sound source, its structure influences the tract above it. The cartilaginous framework of the larynx, particularly the thyroid cartilage, functions as a fixed acoustic boundary condition. Changes in subglottal pressure, mediated by the respiratory system, indirectly affect the tract's resonant properties by altering the longitudinal tension of the vocal folds, which subtly changes the impedan…
