    utility for both clinical and research applications
  17. Aerodynamic Studies Pressure flow technique
    based on a theory that states that the area of ______ can be determined by _____ and _____?
    an opening

    measuring the sirflow through and pressure drop across that opening
  18. Aerodynamic Studies Pressure flow technique
    As applied to VP function for speech: the mm extent of opening in the VP can be determined by measuring__?
    nasal airflow (thru a nostril) and the difference in air pressure between the mouth (oral pressure) and the other nostril (nasal pressure) as measured by a pressure-sensing tube.
  19. Pressure-flow-technique does not?
