Splet7 This cycle repeats itself as long as phonation is sustained. 3 The vocal folds then blow apart/vibrate, opening from bottom to top. 2 There is an increase in subglottal pressure. 1 To initiate phonation, the vocal folds need to be adducted through contraction of the LCA and IA muscles. 6 A sound wave is produced in the vocal tract. Splet11. mar. 2024 · Electroglottography (EGG) is a method for measuring vocal fold contact area during sustained phonation. It is noninvasive. Contact electrodes are placed against the thyroid laminae, and a slight current moves between the electrodes; the resulting signal indicates the amount of contact area between the vocal folds. So, the more … Splet04. jun. 2024 · The process of phonation occurs in the larynx, commonly called the voice box, due to the self-sustained vibrations induced in the vocal folds by the airflow.
