Ch. 6 - Phonation II Flashcards
(23 cards)
Measurement of fundamental and intensity in three main categories
HMS pinafore
1) Habitual use levels (normal life)
2) Max performance tasks (capabilities - how far can you go)
3) Regularity/stability
span lowest to highest freq
M.F.R.P.
Maximum frequency range of phonation
average fundamental at which we speak
Mean speaking fO
range of fundamentals with which we usually speak
M.S.F.R.
Mean speaking fO range
variability/irregularity in a system
Perturbation
short-term involuntary fundamental perturbation measured through sustained vowel phonation
Jitter
short-term variability in amplitude of acoustic waveform
Shimmer
___ has to do with pitch perturbation and ___ has to do with amplitude perturbation
jitter; shimmer
a person’s __ __ __ is their relationship between their intensity and frequency
voice range profile
In a healthy voice’s VRP, they will have the most dynamic range in the ____ and the least dynamic range ___
in the middle; towards the ends
volume of air that passes a given point in mL/sec
mean airflow
formula for aerodynamic power
Mean lung pressure x mean glottal flow
in regards to testing for vocal efficiency, what does MPT stand for?
max phonation time
duration of maximally sustained vowel
Maximum phonation time
Vital Capacity / max phonation time
Phonation quotient
analysis of vibratory mvt of VF during phonation using any one or combo of tools
Glottography
Test using pulsing light to simulate mvt at rate slower than actual rate
Stroboscopy
excessive contraction of intrinsic and extrinsic laryngeal muscles
Muscular hyperfunction
ratio of open phase to whole glottal cycle
Open quotient
ratio of duration of opening phase of VF to duration of closing phase
Speed quotient
ratio of period during which VF in contact to whole glottal cycle
Contact/closed quotient
series of consecutive fO values of approximately equivalent vocal quality
Vocal register
three main vocal registers for postpubescent voice
Pulse
Modal
Falsetto/loft
