COMD 5070 Exam 2 - Questions With Fully
Explained Solutions
Fundamental frequency Correct Answer - The speed of vocal
fold vibration
fundamental frequency Correct Answer - A physical
measurement
Fundamental Frequency Correct Answer - can be derived by a
computer
Fundamental Frequency Correct Answer - Most responsible
for determining our perception of pitch
Fundamental Frequency Correct Answer - the lowest
frequency/ slowest repeating pattern in the sound wave*
Can complex waves still be periodic? Correct Answer - Yes
"You can have repeating components when the sound is simple,
when there's just one frequency present, or when the sound is
complex and there's multiple frequencies present"
What does it mean to be nearly periodic? Correct Answer -
There is a repeating pattern, but not perfectly periodic
Ex. jitter and shimmer
- some signals have minor deviations
nearly periodic Correct Answer - the vocal folds open and
close at basically the same speed but there are tiny little variations
,What is the period of a sound? Correct Answer - a signal or
repeating sound
what is the period of a sound Correct Answer - The amount of
time a single peak cycle (wave) takes
-1/F0 = one divided by the fundamental frequency
What does the Hz unit mean... can you explain it in your own words?
Correct Answer - The number of wave cycles (frequency)
passing through a given point in a second
-1 cycle per second
Why would SLPs be interested in measurements of fundamental
frequency? Correct Answer - -If the client is not happy with the
pitch they are speaking at
-If the client sounds more monotone
-If the client had a more rough/hoarse voice
-To calculate any perturbations a client might have
-We need precise measurements to see the tiny changes from cycle
to cycle
why are slps interested in measuring fundamental frequency
Correct Answer - measurements can helps track changes when
establishing an appropriate pitch for your client
why are slps interested in measuring fundamental frequency
Correct Answer - you need very precise measurements of F0 to
be able to measure perturbation
When the vocal folds vibrate faster/slower, what is the perceived
change in a person's voice? (e.g. is it louder, softer, higher, or lower
, in pitch?) Correct Answer - as vocal folds vibrate faster the
speakers pitch is perceived to be higher
slower vibrations Correct Answer - pitch is perceived to be
lower
vibrating faster Correct Answer - higher perceived pitch
vibrating slower Correct Answer - lower pitch
Describe the different registers of vocal fold vibration. Correct
Answer - - vocal quality changes at pitch extremes
- a pattern of vocal folds vibration
- physiology changes across these
modal register Correct Answer - chest voice
pulse register Correct Answer - vocal fry
Modal Register (chest voice) Correct Answer - -typical
speaking voice and mid-range singing
-Wide dynamic range
-We can change our fundamental frequency up and down
-Lower our voice and raise our voice in terms of pitch and loudness
-The whole mass of the vocal fold oscillates (the entire vocal fold is
used to produce this register)
*Mucosal cover is oscillating
*Collagen and elastic fibers within the vocal folds is oscillating
*Muscle inside the vocal folds is oscillating
Glottal fry. (Pulse Register) Correct Answer - • voice has a
crackly quality
• occurs at very low F0 range
• vocal folds relatively slack
