Representing Sound as Pressure Waves
Sounds are pressure waves reaching our hearing apparatus by the movement of surrounding air molecules. Studying waves helps us to understand basic transport mechanisms.

Diffraction of Sound Waves
Why is it, that if a person hides from us around the corner of a building, this person can still hear the sounds we make, even if there are no reflecting surfaces nearby?
diffraction of sound waves • bending of waves • pressure waves • wavelength of sound • frequency of sound waves

How the Ear Works
The cochlea, a structure in the inner ear, changes sound waves into electrical signals that get sent to the brain. The cochlea also determines the pitch of sounds.
