1

All of the following are biological functions of the larynx except: 

protectig the respiratory system from food and liquid

providing a amechanism for gas exchange

increasing intrathoracic pressure during exertion, coughing, and other bodily functions

controlling airflow in and out of the lungs

providing a mechanism for gas exchange

2

during phonation the muscularly determined position fo the vocal folds is

open 

closed

closed

3

the vocal folds can be considered elastic because: 

they cannot be deformed

once deforemed they stay in teh new posion indefinitely

after being deformed they return to thier normal configuration

of their cellular composition

after being deformed they return to their normal configuration

4

ndamental frequency of adult males vocal fold vibration is 

100 Hz

5

True or False

Although longer and more massive vocal folds vibrate more slowly than shorter and less massive vocal folds raising pitch in an individula speaker is achieved primarily through stretching the vocal folds

true

6

the muscles of medial compression are the (blank) and the (blank) 

posterior coricoarytenoids, lateral cricoarytendoids

posterior cricoarytenoids, interarytenoids

throvocalis, psterior cricoarytenoids

lateral cricoarytenoids, interarytenoids

lateral cricoarytenoids, interarytenoids

7

In the body-cover model of the vocal folds the "body" is considered to be the 

epithelium

lamina propria

thryoarytenoid mucle (thyrovocalis portion) 

thyroarytenoid muscle (thyrovocalis portion) 

8

in the Body-cover model of the vocal folds, during vibration the body and cover

have different vibratory properties

always bibrate ias a single unit

must be stiff

must be tightly coupled

have different vibratory poperties

9

The body-cover model explains why the periodic wave produced by the vocal fold vibratio is 

simple 

complex

contains only one frequency

low-frequency

complex

10

the laryngeal specturum consists of (blank)

a single frequency ie the fundamental frequency

the fundamental frequency plus whoe-number multiples ofhte fundamental frequency

the fundamental frequency plus intervals of 200 Hz

the fundamental frequency and series of subharmonics 

the fundamental frequency plus whole-humber multiples of the fundamental frequency 

11

If the period of a sound wave is .25 ms what is its frequency? 

4000 Hz

12

True or False? 

A single air molecule can travel for hundreds of yards in response to the movement of an osscilator

False

13

If the 5th Harmonic of a complex periodic wave has a frequency of 600 Hz, the fundmental frequncy of the wave is: 

125

150

200

100

125 Hz

14

In a complex periodic wave each frequency component is a whole-number multile of the (blank) of the wave

fundamental frequency 

15

Two sound waves of the same frequency but different amplitudes are produced in phase.  If these waves were combined, the resulting sound wave would: 

a. have a higher amplitude than the first, but a lower amplitude than the second

b. have a higher amplitude than either sound wave

c. be out of phase, and there fore have a lower amplitude then either original sound wave

d. be silence

have a higher amplitude than either sound wave 

16

What does Fourier analysis do? 

a. takes a complex aperiodic wave and reduces it to a set of frequency components int eh time domain (ie showing changes over time) 

b. takes a complex periodic wave and reduces it to a time-varying intensity signal 

c. takes a complex periodic wave and reduces it to a set of simple sine waves at their respective amplitudes 

d. re-calculates a complex periodic wave into a frequency x time display

takes a complex periodic wave and reduces it to a set of simple sine waves at their respective amplitudes

17

teh loudness ofa sound is objectively measured in dB, whichcan be based on physical measures of either intensity or pressure. Most individuals who study speech and/or hearing base dB on  (blank) 

intensity

pressure

pressure

18

aperiodic complex waves contain (blank) 

one frequency component 

a fundamental frequency and multiple frequencies that are harmonically related

multiple frequencies that are not harmonically related

requencies that are 180 degrees out of phase

multiple frequencies that are not harmonically related 

19

in order to raise pich, the vocal folds must be stretched or elongated by the (blank) muscle

cricothyroid

20

When attempting to increase the intesity (loudness) of phonation it is important to increase resistance/tension in the laryngeal muscles so that the aerodynamic force of (blank) can be increased

subglottal pressure

21

The main muscles of the velopharyngeal closure are the (blank) and the (blank) 

a. levator palatine, superior constrictor

b. middle constrictor, inferior constrictor

c. palatoglossus, palatopharyngeus

d. stylopharyngeus, salpingopharyngeus

levator palatine, superior constrictor

22

True or False

The resonatign cavities of the vocal tract (with one excepton) are variable in size

true

23

The extrinsic musle of the tongue most important for positioning the tongue correctly for the /i/ sound is: 

styloglossus

hyoglossus

genioglossus

superior longitudinal

genioglossus

24

 The extrinsic muscle of the tongue most important for positioning the tongue correctly forhte /u/ sound is (blank): 

styloglossus

hyoglossus

genioglossus

superior longitudinal

styloglossus

25

Obicularis oris is most important in producing which vowel sound? 

/i/

/u/

/a/

/u/

26

True or False

Decreasing the air pressure in the lungs results in inhalation

True

27

The pleural linkage causes: 

rest breathing to occure 

the pelvic adn pectoral girdles to support respiration

the ungs to expand or contract with rib cage and diaphragm movements

the medulla to be sensitive to concentrations of oxygen and carbon dioxide in teh blood

teh lunds to expand or contract with rib cage and diaphragm movements
