CSD 475 phonation workbook questions
phonation threshold pressure:
Is the lower lung pressure required to initiate phonation
the Lombard effect tells us that:
People tend to increase their vocal intensity when speaking within noise
all of the intrinsic laryngeal muscles receive innervation from cranial nerve:
X vagus
all extrinsic laryngeal muscles are innervated by:
a combination of CN V, CN VII, CN XII
the cricothyroid joint:
allows the thyroid cartilage to rock forward and downward to achieve vocal fold elongation
adduction
closing of VF
the abduction and adduction of the vocal folds is achieved by movement of the:
cricoarytenoid joint
increased fundamental frequency is achieved by elongating the vocal folds, which ____________________ their stiffness and _______________ their mass per unit length
decreases increases
during VF vibration, the arytenoid cartilages ______________ adduct and abduct the VF
do not
three features of vocal fold closure that are important in the regulation of intensity are:
duration, speed, degree
in the body cover mechanical model of the VF, the body consists of
epithelium and the superficial and intermediate layers of the VF
T/F short term cycle to cycle variability in the amplitude of VF vibration is called shimmer
false
T/F the bernoulii effect is the primary means by which the VF are adducted into the airstream during phonation
false
T/F voice quality refers to pitch and loudness
false
during VF vibration, the restorative forces of the VF tissues:
help to return the VF to their midline position
the major regulator of intensity is:
increased lung pressure
In the three-layer mechanical model of the VF, the vocal ligament consists of the:
intermedia and deep layers of the lamina propia
Short term (cycle to cycle) nonvolitional F0 irregularity is referred to as:
jitter
during VF vibration, the arytenoid cartilages:
maintain adduction of the VF
during VF vibration, the air pressure below the VF:
must be greater than the air pressure above the VF
Abduction
opening of VF
the movement of the cricoarytenoid joints is the:
primarily rocking
all intrinsic laryngeal muscles except for the cricothyroid muscle are innervated by the:
recurrent laryngeal nerve
all intrinsic muscles except for the cricothyroid muscle are innervated by the:
recurrent laryngeal nerve
fundamental frequency is controlled by:
the mass per unit length and the stiffness of the VF
T/F the myoelastic aerodynamic theory of voice production describes passive vibration of the vf when adducted into the airstream
true
breathy onset:
vf approximate after exhalation is initiated
hard onset:
vf are firmly approximated prior to initiation phonation
the myoelastic aerodynamic theory of voice production tells us that:
vocal fold vibration occurs passively due to the interaction of the aerodynamics and the biomechanical properties of the vocal fold tissues
the glottal resistance is the amount of resistance of the __________________ to the airflow
vocal folds
gentle onset:
vocal folds approximate at the same time as exhalation is initiated
