The Physics of Sound
Jahnai Aikens
Teters block 2
Overview
- Facts of Sound
- The Ear Sound
- Sounds Properties
is a form of evergy produced and transmitted by vibrating matter.
and travels faster through sloids than liquids
or gases.
The Ear
sound is heard through our ears from vibrating air molecuels. Sound waves move through 3parts of our ears.
- Outer ear
- Middle ear
- &Inner ear
Vibration
is a back and forth motion of molecules of matter
Compression
ocurrs when molecules are pressed together as the sound waves move through matter
Sound Waves
have alterative areas of high and low pressure in the air.
all sound is carried through matter as sound waves
Wavelength and Frequency
is the full distance between the peak of the wave
is the number of waves moving past a point per second
Pitch
is a measure of how high or low a sound is. A pitch depends on the frequency of a sound wave

what did I take from this experience?
ANY questions FOR MEE!!!
why did i choose this particular project?
Did i have fun doing it?
