Properties of Sound
How we hear
100
Crest
What is the highest point on a wave.
100
disturbance that transfers energy from place to place
What is a wave?
100
set of notes that combine in patterns that are pleasing
What is music?
100
unit for measuring loudness
What is a decible?
100
This is where sound waves are interpreted.
What is the brain?
200
The lowest point on a wave.
What is the trough?
200
Medium
What is the material through which a wave travels?
200
This is what a wave transfers.
What is energy?
200
waves with frequency above normal human hearting
What is ultrasound?
200
These are the three smallest bones in the body, also located in the ear.
What are the hammer, anvil, and stirrup?
300
maximum distance away from resting point in a wave
What is amplitude?
300
Perception of energy of a sound
What is loudness?
300
Longitudinal or compressional.
What is the type of wave for sound?
300
change in frequency of a wave as its source moves
What is the Doppler Effect?
300
These are the three main parts of the ear.
What are the outter ear, middle ear, and inner ear?
400
wavelength
What is the distance between two corresponding parts of a wave?
400
Hertz (Hz)
What is the unit for measuring loudness?
400
These three things are what the speed of sound depend on . . .
What is elasticity, density, and temperature
400
Infrasound
What is the frequency below normal human hearing?
400
This part of the ear is found just after the three bones and it contains fluid and tiny hairs that vibrate when sound waves are passing through.
What is the colchlea?
500
Frequency
What is the number of complete waves that pass a given point?
500
When frequency in creases this is what happens to wavelength . . .
What is decreases?
500
This is how longitudinal and transverse waves are similar (name two).
What is they transfer energy and they require a medium?
500
How high or low a sound seems to a person.
What is pitch?
500
This is where the sound wave turns into something different.
What is the auditory nerve?
