more visual representations of sounds and resonance & anatomy of the respiratory system
True or False: Harmonics can be seen on a line spectrum
True
What are the different types of lung volumes?
tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume
True or False: Spectrogram is another way to represent speech sounds
True
What are the different types of lung capacities?
vital capacity, functional residual capacity, inspiratory capacity, and total lung capacity
Each lung is covered on the outside by a thin membrane called...
a. parietal space
b. pleural space
c. the visceral pleura
d. intrapleural pressure
c. visceral pleura
Why does the volume of the lungs increase during inspiration the alveolar pressure increases?
Boyle's Law
True or False: Air moves from areas of low to high pressure
False
What is one of the 5 major changes when switching to breathing for life and breathing for speech?
location of air intake: inhaling and exhaling for life breathing takes place through the nose; inhaling and exhaling for speech occur through the mouth
ratio of time for inhalation vs. exhalation: life breathing → inhale 40%, exhale 60%; speech breathing → inhale 10% exhale 90% **makes speech more efficient because it is produced on the exhale
volume of air inhaled/exhaled: more for speech breathing, increases with louder and longer utterances
muscle activity for exhalation: life breathing → exhalation is passive, relies on recoil forces; speech breathing → muscle activity is utilized. Inspiration muscles continue to contract to prevent the lungs from depleting too quickly chest wall shape
life breathing → abdomen displaced outward relative to rib cage
speech breathing → abdomen placed inward relative to rib cage
True or False: When the diaphragm is relaxed it is moved downward and the lungs expand and inflate
False
What is a characteristic of a person’s speech/voice with Parkinson’s Disease?
monotone, imprecise articulation, breathy, low intensity and weak; breathy and weak typically due to poor respiratory support
