Lecture 14 Flashcards
What are the 3 conditions for starting phonation?
1) bringing the VFs together
2) exert tension
3) air flow/supply from lungs
The myoelastic/aerodynamic thearoy explains what?
Phonation/VF behaviors
VF opening and closing is regulated by what two things?
1) the degree of tension in the VFs
2) aerodynamic events
What is the Bernoulli effect?
Increased velocity of air molecules generates negative air pressure
What aerodynamic factor opens the VFs to repeat vibratory cycles?
Positive pressure below the VFs
What are the four steps of phonation?
1) VF approximation
2) positive subglotal pressure
3) puff of air emitted
4) folds return to the midline
What two prices return the VFs to the midline?
1) tissue elasticity
2) negative glottal pressure
Incomplete closure of the VFs results in an OQ of ____%
100%
Pitch is a _________ concept
Perceptual
Pitch is related to the ___ at which ______ _____ vibrate and the objective correlate is ________ _______
Rate; vocal folds; fundamental frequency
What are the 3 pitch raising mechanisms?
1) length
2) tension
3) mass
what are the 3 voice registers?
1) normal/modal
2) falsetto
3) vocal fry/glottal fry/pulse register
Loudness is the perceptual correlate of _______ and its physical correlate is ________ ___ _____
Intensity; subglottal air pressure
With increased intensity, the closure duration of the VFs is ______
Longer
_____ and ______ often increase together but dont have to
Pitch and loudness
