Quiz 4

Question 1

What are the 3 primary parameters for voicing?

Answer 1

How far apart the vocal folds are
Whether the larynx is raised or not
Timing (duration, relative)

Question 2

What is glottal actions role in voicing?

Answer 2

Orchestrate muscles in the larynx to create a condition where vibration is possible if there is the right amount of pressure
Bernoulli’s principle

Question 3

Describe Bernoulli’s principle?

Answer 3

Principle that makes airplanes fly
Air flows through the vocal folds and they are blown apart
Pressure in the vocal folds is lower than the sub and supra glottal pressures
This pulls the vocal folds back together

Question 4

What are the requirements for voicing?

Answer 4

Vocal folds need to be in ready position
Sub glottal pressure must be 2cm H20 greater than the supraglottal pressure

Question 5

What are the types of non-modal voicing?

Answer 5

Voiceless
Breathy
Modal
Creaky
Glottal closure

Question 6

Describe creaky voice

Answer 6

Arytenoid cartilages are tightly together and only the anterior end vibrates

Question 7

Describe breathy voice

Answer 7

Vocal folds are looser and more air gets through with each cycle

Question 8

What is a transverse wave?

Answer 8

When the particles in a wave travel up and down

Question 9

What is a longitudinal wave

Answer 9

Particles in a wave travel back and forth
Greater the amplitude means higher compression

Question 10

What is frequency?

Answer 10

Number of times a full cycle repeats per second (measured in Hz)
Acoustic property

Question 11

What is amplitude?

Answer 11

The distance between the zero line and the peak
Strength of the oscillations (measured in dB)

Question 12

What is phase?

Answer 12

Point in time when the wave started relative to another wave

Question 13

What is the difference between wavelength and period?

Answer 13

Wavelength: the distance from peak to peak
Period: the time from peak to peak
