Q

what are the 5 mechanisms involved in one cycle of glottal vibration that results in vocal fold vibration in ADMET

A
  1. the adductor muscles (LCA and IA) close the vocal folds while the tenors (CT and TA) stiffen the vocal folds to the desired fundamental frequency
  2. as person begins to exhale, sub glottal pressure builds beneath the vocal folds. pressure builds until it is great enough to overcome the resistance of the vocal fold and push the folds open
  3. a glottal pulse is released creating an acoustic shock wave traveling through the vocal folds
  4. once the folds have been blown open forces of the elastic recoil and the bernoulli effect help to bring the folds back to there original position
  5. the opening and closing of the vocal folds during phonation is the result of the aerodynamic and muscular foyers indicated above

Q

what does the cover-body theory of vocal fold vibration state?

A
  • the vocal fold cover moves independently of the body
  • the TA muscle (body) participates very little in vibratory movement
  • movement of the vocal ligament falls in between the significant movement of the cover and the minimal movement of the body
  • this theory suggests that anything that interferes with the movement of the cover will affect the resulting voice quality
