1. Speech breathing is generated by a combination of active (muscular) and
passive (recoil) forces.
True
False
2. Boyle's Law states that for an ideal gas at a constant temperature,
if pressure increases, volume increases.
True
False
3. In both liquids and gases, pressure is transmitted rapidly and uniformly
throughout the space occupied by the liquid or gas.
True
False
4. As an incompressible fluid in a duct goes through a narrowing or constriction
(glottis), the velocity of particles of air must increase to maintain the
relationship defined by: U = vA, where U = flow, v = particle velocity, and
A = cross-sectional area.
True
False
5. On inhalation, the gauge (or relative) pressure in the lungs is negative.
True
False
6. Glottal resistance is the ratio of glottal flow to the pressure driving
the flow.
True
False
7. Resting tidal volume is usually less than 50% othe vital capacity.
True
False
8. Typical lung pressures for speakers range between 30 and 120 KPa. with
an average of 70 KPa.
True
False
9. The viscera is the part of the body extending from the shoulders upward.
True
False
10. In a soft-walled enclosure (e.g., the lungs) at a constant temperature,
if the volume of air increases, the pressure decreases.
True
False
11. With respect to laws of fluid flow in ducts, both liquids and gases
are considered to be fluids.
True
False
