The sound waves are collected by the pinna and then are directed through ear canal. The sound waves on striking the eardrum make it vibrate exactly the same way as the given sound emitting object. The bones in the middle ear start vibrating when the eardrum vibrates. It help in magnifying the vibrations. When the magnified vibration reach the cochlea in the inner ear the fluid in it start vibrating. These vibration are picked up by senory receptors and are converted into electrical signals. These electrical signals then travel to the brain which interprets sound.

Answer:
1) The pinna, collects the sound.
2) The sound wave then travels through the auditory canal which funnels the sound to the ear drum causing it to vibrate.
3) The ear drum then amplifies the sound by vibration of bones. It is in the middle ear where sound energy is converted into mechanical energy.
4) The cochlea in the inner ear converts the vibrations into electrical impulses before sending signals to the brain.
5) The brain then interprets the impulses sound.
