Sound
This is how sound travels
In longitudinal waves
This is the speed of sound
in dry air at 20 degrees C---- 343 m/s
The ear is made up of what three parts
Outer Ear, Middle Ear, Inner Ear
This is where sound enters the ear and helps determine the direction.
The outer ear
This is how sound waves are transmitted
through a medium (solid, liquid or gas)
As temperature increases, what happens to the speed of sound
it increases
This separates the inner and outer ear.
Tympanic membrane
The is the role of the tympanic membrane.
It converts acoustical energy to kinetic energy.
vibrations of an object that create mechanical waves propagating through a medium
If a medium is stiffer, does sound travel faster or slower
faster
These are the parts of the middle ear.
Ear drum and three bones (hammer, stirrup, anvil)
This is the role of the ear drum.
To amplify the sound
all possible sound waves
This is the relationship between the wavelength and frequency?
The shorter the wavelength, the higher the frequency.
indirect relationship
This connects the middle ear to the throat
the eustachian tube
This is the role of the Eustachian tube
to equalize air pressure
This is why SONAR is used
to measure the distance
This is the definition of sound intensity.
The rate at which sound waves transmit energy
This is the main portion of the inner ear
cochlea
What is the role of the cochlea
The sound vibrations are converted to electrical impulses and sent by cells to the auditory nerve
