A decrease in the length of a tube__________all resonant frequencies.
Increases or decreases - Answer- Increases
T/F. Children have a shorter vocal tract than adults. - Answer- True
Determine the length of a tube closed at one end that could amplify a tuning fork that
resonates at 500 Hz (speed of sound = 340 m/s). - Answer- 0.17m
T/F. There is only 1 unique closed-at-one-end tube that can amplify a tuning fork with
the frequency of 500 Hz. - Answer- False

d. Spectral slope
e. All of the above - Answer- e. All of the above
T/F. Characteristics of speech is shaped by characteristics of vocal folds and
articulators. - Answer- True
T/F. Each time the vocal folds snap shut, it initiates a pressure wave that propagates
through the vocal tract. - Answer- True
, T/F. Perturbation theory can quantitively and accurately predict effects of constrictions
on resonant frequencies of tubes. - Answer- False
T/F. Tongue height correlates well with the third formant frequency. - Answer- False
T/F. Tongue Advancement correlates well with the fundamental frequency. - Answer-
False
T/F. As the constriction created by the tongue moves toward the front of the mouth, the
second formant frequency increases. - Answer- True
T/F. Lip rounding increases the length of the vocal tract. - Answer- True
T/F. In English, back vowels have more lip rounding than front vowels. - Answer- True

frequency domain
T/F. Relative to wideband spectrograms, narrowband spectrograms have better time
resolutions. - Answer- False
T/F. Narrowband spectrograms highlight the overall shape of amplitude spectrum
(spectrum envelope). - Answer- False

resonant frequencies.
a. amplify/pass
b. attenuate - Answer- amplify/pass
What happens to resonant frequencies of a one-end-closed tube if we increase its
length?
