Sounds are created by vibrations of something.
What causes sound?
100
Is how much energy travels through an area.
What is intensity?
100
Is sound in a deliberate pattern.
What is music?
100
The study of sound.
What is acoustics?
100
Sound travels fastest in solids.
What does sound travel fastest in?
200
Sound can travel easily through solids, liquids, and gases. It cannot pass through empty space.
What can sound travel through?
200
The human perception of sound intensity.
What is loudness?
200
The vibrating at specific frequency.
What is resonance?
200
Many echoes from one place.
What is reverberation?
200
Sound travels slowest in air.
What does sound travel slowest in?
300
Speed of sound mainly depends on the temperature and the kind of medium it travels through.
How fast can sound travel?
300
Is how high or a sound is.
What is pitch?
300
The use of resonator to make a string louder.
What are strings?
300
Locating objects by emitting sound.
What is echo location?
300
Hammer, anvil, and stirrup.
What are the three bones of the ear?
400
Inner, middle, and outer ear.
What are the different parts of the ear?
400
Sound waves that are above 20,000 hertz and people can't hear.
What is ultrasonic?
400
The vibrations of air.
What is the bass and woodwind?
400
Emitting sounds underwater for locating things.
What is sonar?
400
The cochlea is spiral shaped and has little hairs with liquid that sends sound up to the brain.
What is the cochlea?
500
The outer ear gathers the sound and sends it through ear canal and eardrum. The middle ear has a hammer, anvil, stirrup, these bones vibrate and amplify the sound as it is transferred to the oval window. The inner ear has a cochlea which is spiral and converts wave sounds to brain.
Explain what the different ear functions do?
500
The change in pitch or wave frequency due to a moving wave source.
What is the Doppler effect?
500
The vibration of a membrane over a resonator.
What is percussion?
500
Able to use sound as an x-ray, clean jewelry, and check for pregnancies.
What is ultrasound?
500
They are the fewest standing waves.
What are fundamental waves?
