Describes your perception of the energy of a sound

100
A set of random notes that are not in a pattern
What is noise?
100
This funnels sound into your ear canal
What is your outer ear?
100
Injury, infection, and exposure to loud sounds cause this
What is hearing loss?
200
What sound waves travel through (making it a mechanical wave)
What is a medium?
200
A description of how "high" or "low" the sound seems to a person
What is pitch?
200
A set of notes that combine in patters to be pleasing to the hear
What is music?
200
A small, tightly stretched membrane over an object in your ear
What is an eardrum?
200
Some animals use this to navigate and find food
What is echolocation?
300
What type of wave sound travels as
What is a longitudinal wave?
300
Sounds with frequencies above the normal range of hearing for humans
What is ultrasound?
300
The study of how sounds interact with each other
What is acoustics?
300
Fluid-filled cavity shaped like a snail in your inner ear
What is the cochlea?
300
A system that uses reflected sound waves to detect and locate objects underwater
What is sonar?
400
A reflected sound wave
What is an echo?
400
Measured in Hertz (Hz); counts the vibrations per second
What is frequency?
400
___________ work to control reverberation in a concert hall, for example
What is acoustics?
400
Separates your outer ear from your inner ear
What is your middle ear?
400
The speed of sound depends on these 3 things
What is the elasticity, temperature, and density of the medium
500
Sound spreads out and/or bends, or does this, when it goes around corners or through doorways
What is diffract?
500
Explain the Doppler Effect
When a sound source moves, the frequency of the waves changes because the motion of the source adds to the motion of the waves
500
When echoes of a sound are heard after the sound source stops producing sound waves
What is reverberation?
500
People wear one of these when their hearing is not at 100%
