When you speak or sing, you force air from your lungs up through your
larynx, cochlea, anvil, hammer
What is the larynx
Sound waves with frequencies above the normal human range of hearing are called
pitch, echolocation, ultrasound, acoustics
What is ultrasound?
When the frequency of sound waves matches the natural frequency of an object, the result can be
dissonance, infrasound, ultrasound, resonance
What is resonance?
The note C-sharp played on a trumpet sounds different from the same note played on an oboe because of
pitch, density, timbre, resonanceWhat is timbre?
The pitch of a sound depends on the
amplitude of the sound wave
interference of the sound waves
intensity of the sound wave
frequency of the sound wave
What is the frequency of the sound wave?
The sound produced when notes that seem to have no musical relationship are played together is called
resonance, infrasound, ultrasound, dissonance
What is dissonance?
Between the ear canal and the middle ear is the
eardrum, hammer, anvil, cochlea
What is the eardrum?
Sound travels more in air than in water
speedy, slowly, droopily, quickly
What is slowly?
One of the main differences between music and noise is that music is to the ear
uncomfortable, hard, pleasing, angry
What is pleasing?
When sound waves interfere, the resulting sound
is always louder
is always softer
is of a different pitch
may be louder or softer
What is may be louder or softer?
The speed of sound depends on all of the following EXCEPT
temperature, loudness, elasticity, density
What is loudness?
The part of the ear that translates sound waves into nerve impulses is the
cochlea, eardrum, hammer, anvil
What is the cochlea?
A sonar device measures the time it takes to detect
beats of a sound
time it takes to detect a reflected sound wave
time it takes to track an animal
pitch of a sound
What is time it takes to detect a reflected sound wave?
A small drum produces a pitch than a larger drum does
lower, medium, higher, equal
What is higher?
The following are all applications of echoes EXCEPT
sonar, echolocation, ultrasound, resonance
What is resonance?
The intensity of sound wave is
measured in decibels
inversely proportional to loudness
the amount of energy the wave carries
determined by how much the sound is below the normal human range of hearing
What is the amount of energy the wave carries?
The eardrum is in the
outer ear
middle ear
inner ear
whole ear
What is the outer ear?
Sound frequencies above the normal human range of hearing are called
infrasound, sound waves, pitch, ultrasound
What is ultrasound?
You notice one key on a piano if playing a note with a pitch that is slightly too high, What would you do to the piano string to fix this problem?
tighten, open up, loosen, close down
What is loosen the string?
Many people suffer hear loss as a result of any of the following EXCEPT
aging, dissonance, injury, infection
The study of how well sounds can be heard in a particular room is called
acoustics, the Doppler effect, pitch, echolocation
What is acoustics?
As a police car speeds by, the pitch of the siren seems to change because of
Timbre
Acoustics
The Doppler effect
Sonogram
What is the Doppler effect?
Sounds with frequencies below the normal range of human hearing are called
infrasound, ultrasound, sound waves, pitch
What is infrasound?
When the interference is destructive, compressions of one wave occur at the same place as rarefactions of another wave and the amplitudes do what to each other
cancel each other out
create a bigger noise
make seismic waves
never existedWhat is cancel each other out?
Sound is a disturbance that travels through a medium as a
primary wave
longitudinal wave
surface wave
seismic wave
What is a longitudinal wave?
