07 - Aerodynamics and Quality of Life Assessment

Question 1

What is a Voice Aerodynamic Assessment?

5

Answer 1

Phonatory Aerodynamic System (PAS)

Vital Capacity

Mean Airflow rate

Phonatory Quotient

Voicing Efficiency

Variation in SPL

Question 2

What is a Normal MALE Vocal Duration?

Answer 2

25-30 sec

Question 3

What is a Normal FEMALE Vocal Duration?

Answer 3

15-20 sec

Question 4

What is Vital Capacity?

Answer 4

The total amount of air being used by the lungs

Question 5

What can we learn from Vital Capacity?

Answer 5

Is the respiratory system functioning

Question 6

How do we measure Vital Capacity?

Answer 6

Take the deepest breath you can then exhale into mask

Question 7

How do we measure Mean Airflow Rate?

Answer 7

Air expelled during Maximum Sustained Vibration / Time

Question 8

What can we learn from Mean Airflow Rate?

2

Answer 8

Is air escaping improperly

Low number =Laryngeal Valving

Question 9

How do we measure Phonatory Quotient?

Answer 9

Vital Capacity / Maximum Sustained Phonation

Question 10

What can we learn from Phonatory Quotient?

2

Answer 10

Respiratory function in speech

Low number = poor respiratory function

Question 11

What is Voicing Efficiency?

Answer 11

Measure of air-pressure to speech

Question 12

What can we learn from Voicing Efficiency?

Answer 12

Airflow Resistance by larynx

Question 13

How do we measure Voicing Efficiency?

2

Answer 13

Patient repeats (apapapapapapapa/), placing equal stress on each syllable.

Measures air pressure at lips

(Assumption is that pressure at the lips is the same as subglottal pressure).

Question 14

What are Variations in SPL?

Answer 14

Loudness change

Question 15

What can we learn from Variations in SPL?

Answer 15

Ability to control subglottal pressure

Question 16

How do we measure Variations in SPL?

2

Answer 16

Patient produces /pa:pa:pa:/ at usual, half usual, and twice usual loudness levels

This is done three times without a break at each loudness level.

Question 17

What can we learn from Maximum Sustained Phonation?

Answer 17

How long a patient can say “ahhhh”

Question 18

How do we measure Maximum Sustained Phonation?

2

Answer 18

Patient takes a deep breath then produces a sustained open vowel (‘‘aaah’’)

Phonation should be at a comfortable pitch and loudness for as long as possible

Question 19

What does Vocal Quality of Life look at?

3

Answer 19

Functional Voice

Voice Physiology

Emotion

Question 20

What are three Vocal Quality of Life measures/tools?

Answer 20

VHI – Voice Handicap index

VR-QOL – Voice related Quality of Life index

VAPP – Voice activity and participation profile
