Arrange the step-by-step process of how human perceive sound. From 1-5.

□Sound is collected by the outer ear and passes through ear canal

□Sound waves transformed into electric signals which are interpreted by the brain.


□The vibration in the ear drums makes three bone structures to vibrate, amplifying the sound

□Air vibrations make the eardrum vibrate in and out, transforming the pressure vibrations into mechanical vibrations.

□The larger amplitude oscillations create travelling waves in cochlea​
