COMD 5070 - Exam 2 UPDATED ACTUAL
Exam Questions and CORRECT Answers
pressure - CORRECT ANSWER - _______ = force per unit area
6, 12, 18 - CORRECT ANSWER - on a laryngeal source spectrum, showing F0 and
harmonics, the F0 is the first and tallest harmonic component
-_____ dB/octave is associated with a bright, resonant voice
-_____ dB/octave is associated with a typical voice
-______ dB/octave is associated with a thin, weak voice
aperiodic, nearly periodic - CORRECT ANSWER - noise is _______ in its waveform,
while the human voice is ______ ________
vowels - CORRECT ANSWER - Pio is equal to atmospheric pressure during the
production of __________
u-tube manometer, electronic equipment, static, dynamic - CORRECT ANSWER -a
________ ________ is a tubed device containing water that is level on both sides until pressure
is applied to it and displaces it
-once pressure is applied, measure the difference in height of both columns, and that will give
you the cm of water that has been displaced by pressure applied
-used to calibrate _____ ______ used to measure pressure
-measures _____ pressure but not suited for ________ pressure of speech production
cmH2O - CORRECT ANSWER - what is the pressure unit of measurement used in speech
research?
,pressure transducer - CORRECT ANSWER - a ________ _________ is a device you stick
in a person's mouth while they speak to measure intraoral pressure
intraoral pressure, vowels, fricatives, stop consonants - CORRECT ANSWER - Pio stands
for _________ _________
-it is equal to atmospheric pressure for _________, elevated for ______, and highest for ______
_______
subglottal pressure - CORRECT ANSWER - Ps or Psub stands for ________ ________
and is the driving pressure for phonation/speech
(pressure from lungs to larynx)
tracheal puncture, esophageal pressure - CORRECT ANSWER - what are 2 ways you can
measure subglottal pressure (Psub)? (1 direct and 1 indirect measure)
tracheal puncture - CORRECT ANSWER - in a ________ ________, a physician creates a
hole in the trachea (below the larynx) & puts a mini pressure transducer into it to measure the
pressure
-provides direct & accurate measures during speech, but it is invasive and hard to attract
volunteers
esophageal balloon - CORRECT ANSWER - because the esophagus shares its anterior
wall with the posterior wall of the trachea, past researchers have indirectly measured Psub using
an _________ __________ which contains a sensor that a person swallows partway into their
esophagus
-this gives an indirect measure of Psub and is not commonly used today
laryngeal devoicing gesture, Pio, Psub - CORRECT ANSWER - when producing a CV
syllable containing a VL bilabial stop such as /p/, the point of lip closure for /p/ produces a
, ______ ______ ______ or abduction of the vocal folds, which then links the trachea and the
mouth, causing ______ to equal ________
-no drop off of pressure at the larynx
5-7, 15-20 - CORRECT ANSWER - Psub values typical for:
-normal speech/conversation: ____ cmH2O
-loud speech/shouting: ____ cmH2O
-clear association between Psub and SPL
because the VF are stretched very tightly for falsetto, requiring more pressure to oscillate them -
CORRECT ANSWER - Psub is lower for pulse register and higher for falsetto, why might
this be?
phonation threshold pressure, 3-5, dehydration, vocal fatigue - CORRECT ANSWER -
PTP stands for ________ ________ _________ and is the pressure needed for the VF to start
vibrating
-between _______ cmH2O is needed to start, but less is needed to maintain it
-PTP increases with _______, and _______ _______
PTP - CORRECT ANSWER - when the VF are dehydrated, they become less
compliant/flexible.
when they are fatigued, they are swollen/bulky. this causes __________ to increase
easy onset, harsh, abrupt onset - CORRECT ANSWER - PTP is lower for _____ ______
where the VF are looser, and is higher for _____ or ______ ______, which some people use
unnecessarily
pressure, flow x resistance, resistance, pressure/flow - CORRECT ANSWER - ohm's law:
