PRESENTATION OUTLINE
Sound is tiny vibrations and movements in the air
Air moves and those tiny waves reach our ears
- Air moves and those tiny waves reach our ears
The ear is cup shaped so it can focus the sound
The sound waves squeeze the air molecules that then funnel through the ear
The waves enter the ear cannel which makes it smaller and goes to the eardrum
The ear drum vibrates which moves the bones in the middle ear which pounds on the seashell shaped inner ear
Then the sounds travels in waves in a fluid which hit tiny hairs
Which sends signals to the brain
Then the brain filters and processes those signals and senses it as sound this process takes under 1/100 of a second
