All Ears
This main part of the ear contains the ear canal, and is where sound waves enter the ear.
What is the Outer Ear?
This type of pitch has a very short wavelength.
What is high pitched?
When a sound wave has many waves per second it has a ___________________.
What is high frequency?
This state of matter has closely packed particles.
What is a solid?
This is what happens to air particles when a sound wave moves through them.
This main part of the ear contains the cochlea.
What is the Inner Ear?
This type of pitch has a very long wavelength.
What is low pitched?
When a sound wave has very few waves per second it has a ________________________.
What is low frequency?
This type of matter has particles that are spread apart.
What is gas?
This is what happens to air particles when the sound source stops producing a sound wave.
This main part of the ear contains the eardrum.
What is the Middle Ear?
This high pitched sound can only be heard by dogs and some other animals.
What is ultrasound?
True or False:
Humans can hear all frequencies.
What is False?
This type of matter has particles that are loosely packed together.
What is liquid?
This is what happens to the spaces between the dense air particles when you increase the force of the sound source.
What is the spaces between the dense particles gets bigger?
Stereocilia are these....in the cochlea.
What are little hairs?
This low pitched sound is often heard as a low hum.
What is infrasound?
What is the wavelength?
Sound waves move quickest through this type of matter.
What is a solid?
This is what happens to the spaces between the dense air particles when you increase the frequency of the sound wave.
What is they get smaller?
This is what is traveling from the outer ear to the brain.
What are vibrations?
This is a special type of sound that bats and dolphins use to communicate and locate food.
What is echolocation?
This is what happens when a sound wave matches the natural frequency of glass.
What is the glass breaks?
Sound waves move slowest through this type of matter.
What is gas?
True or False:
Sound waves cannot travel in a vacuum. (Hint: no air)
What is True?
