Collect sound from surrounding area to channel and convert into electrical
impulses for the brain to interpret.
* A sensory organ.

-gathers sound waves and funnels into the middle ear.
MIDDLE EAR: Eardrum-entrance of the middle ear.
vibrates due to sound then sets off
to occur with three middle ear
3 bones: Hammer, Anvil & Stirrup
vibrations make each vibrate and
set off the
Named by their shapes.
Connected to nose by Eustachian tube.
create waves/tappings for the neurons to bring
info to the brain to interpret.
-snail tube shaped. fluid-filled
to respond to sound waves.
CANALS- loops above the cochlea to help with balance. Fluid-filled that reacts to movement and send info to the brain to interpret and
adapt . -Adjustment to position of the head.
*STRUCTURED TO RECEIVE VIBRATIONS TO HEAR. (CSS 5g)
by pushes of air. Waves sent away from source of sound (ripple effect).
Travels through gases (air), liquid, and solids.
Doppler Effect- pitch of sound changes with distance.
When moves to
you=pulses faster and pitch higher.
When moves away from you= pulses slower and pitch lower.
*Used for sound effects
