vibration - sound waves go out into the air, vibrates through the particles, comes to our eardrums and our eardrums vibrates back and forth. , transverse wave - the particles moves up and down, volume - is the size of the vibration, small vibration - the wave won't have a lot of energy and the vibrating hitting your ear will be light., large vibration - the wave will have lots of energy and the vibration hitting your ears will be more intense (extreme). This is a loud sound., pitch - how many times the vibration hits your ears every second (hertz -htz), hertz - htz - vibrations of sound, frequent vibrations (fast) - the higher the sound, few vibrations (slower) - the lower the sound, compression waves - longitudinal waves , sound compression waves - waves move through matter (solid, liquid, or a gas), the molecules of the matter move backward and forward in the direction in which the wave is traveling.,
