Phys exam part 1-2 questions & answers
2024/2025
Brass instruments - ANSWERShave overtones that are not always harmonic to the pedal tone
The most important factor listed below in determinging the timbre of a wind instrument is -
ANSWERSthe shape of the pipe that forms the 'air column"
At 35C (for which the velocity of sound is 352 m/s), what is the frequency of the second
overtone for closed ended cylindrical tube with an effective length of .40m? - ANSWERS1100 Hz
The resonances of the vocal tract when modeled as a closed-ended cylindrical tube occur
approximately at which of the following frequencies? assume the vocal tract is 17 cm= .17m
long - ANSWERS500 Hz, 1500 Hz, 2500 Hz
Which of the following defines the term edge tone? - ANSWERSvibrations produced by fluid-
flow instability when a narrow stream of air is directed against a sharp edge
piping' pete is playing at city park next weekend. one of his open-end pipes is capable of
sounding its first harmonic at 500 Hz. The speed of sound in the pipe is 350 m/sec. what is the
length of the air column inside the pipe? - ANSWERS.35m
The flute is one of the few woodwind instruments that does not use a - ANSWERSreed
A vocal (glottal) fry is - ANSWERSa mode or posture of the vocal folds
, reflections happen at open holes in a woodwind because of the - ANSWERSabrupt change in the
impedance of the pipe caused by the hole
the speed of sound on a humid day is faster than on a day with low humidity. If a pipe organ is
designed to play in a region with low humidity, what will happen to the fundamental tone
produced by the same pipe organ on a rainy, humid day? - ANSWERSthe pitch goes up
a trombone is most simply modeled as a closed-ended cylindrical tube. if the trombone tubing
is 2.7m long, what is its fundamental frequency? Assume T=20 - ANSWERS32 Hz
the sound of a flute is different to the sound of a clarinet playing the same note because: -
ANSWERSthey produce different harmonic recipes
where would you fine the vocal folds (vocal cords)? - ANSWERSlarynx
what jet velocity must a flautist provide with a gap = 0.01 m to produce an edge tone of 880 Hz
(A5) - ANSWERS44 m/s
which of the following are all member of the woodwind family? - ANSWERSbassoon,
saxophone,oboe,clarinet
for brass instruments: - ANSWERSthe bell causes a shift in the low frequency modes to higher
values
a oboe is a stopped pipe because at the reed the pipe is closed - ANSWERSpulses of air pressure
from the reed "valve"
several types of reeds, including the double reeds of the woodwinds, the lips reeds of brass
instruments, and the vocal folds, rely on the bernoulli principle to help them vibrate. The
bernoulli principle states that - ANSWERSthe higher the velocity of air the lower its pressure
