human ear is the most sensitive part in human beings and they allow to convert the pressure variations in the ear into electrical signals that are send to brain by auditory nerves.
WORKING
1. outer ear is called pinna which helps to collect the sond waves from the surroundings
2.they are then sent to auditory canal which is the passage of sound.
3.at the end of human ear there is an ear drum also called tympanic membrane.
4.now the vibration reach the middle ear which is made upnof three bones -hammer anvil and stirrup. they amlify the sound waves.
5.now the sond reaches the inner ear which includes cochlea which helps to convert pressure variations into electrical signals
6.these electrical signals are send to brain by auditory nerves and are interpreted as sound.
