1. The open quotient of the glottal airflow waveform i
s the ratio of the fall
time (negative-going portion) to the rise time (positive-going portion).
True
False
2. A breathy voice will create a steeper spectral slope than a pressed
voice.
True
False
3. A reflection coefficient of 0 (zero) means that the amplitude of the
reflected wave is as big as the amplitude of the incident wave.
True
False
4. When an arrow is used to represent a wave at an interface, a minus sign
placed over the arrow indicates a compression of air at the moment in time.
True
False
5. A harmonic is a sinusoidal component of a complex tone whose frequency
is an exact integer multiple of the fundamental frequency.
True
False
6. The open quotient and the skewing quotient define the shape of the glottal
flow waveform.
True
False
7. A sound will register on a sound pressure level (SPL) meter as 10 dB
less whenever whenever the distance between the sound source and the SPL
meter is doubled.
True
False
8. "Wavelength" and "period" both refer to the distance from peak to peak
of a waveform, but the horizontal axis represents time when we call it "wavelength," and
it represents distance when we call it "period."
True
False
9. The speed (velocity) of a porpagating wave depends on the elastic and
inertial properties of the medium. The nature of this relationship is:
density increases - velocity decreases
elasticity increases - velocity increases.
True
False
T 10. Sound is generated when ambient pressure in a stationary or slowly
moving air medium is suddenly disturbed locally.
True
False
