Heya...here is your answer ✌
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Working of Human Ear:-
>The sound waves from the outside is collected by the pinna of the outer ear.
These sound waves then move through the Auditory Canal( Ear canal).
>These sound vibrations then strike the tympanic membrane(ear drum) and let it also on vibrate. These vibrations are then carried onto three small bones namely hammer , anvil and stirrup of the middle ear one by one. The function of these bones is to amplify the sound waves.
> After that , from the last bone that is stirrup these vibrations are transferred into the cochlea of the inner ear. The liquid present in cochlea coverts these sound waves into electrical signals which are then transported to the brain by auditory nerves.
>The brain then interprets them as sound.
hope this helps ☺✌

Working of human ear.
The sound waves are collected by the pinna of outer ear. These sound waves pass through the ear canal and falls on the eardrum. Sound waves consists of compressions and rarefactions. When the compression of sound wave strikes the eardrum the pressure on the outside of a drum increases and pushes the eardrum inwards and where the rarefactions of sound wave falls on the eardrum the pressure of the outside of ear drum decreases and it moves outward.
When the sound waves fall on the eardrum the eardrum starts vibrating to and fro rapidly.
Thevibrating ear-drum causes as small bone hummer to vibrate from hummer, vibrations are passed on to the second bone anvil and finally to the third bond stirrup. The vibrating stirrup strikes on the membrane of the oval window and passes its vibrations to the liquid in the cochlea. Due to this the liquid in the cochlea begins to vibrate. The vibrating liquids of cochlea setup electrical impulses in the nerve cells present in it.
These electrical impulses are carried by auditory nerve to the brain. The brain interprets this electrical impulses as sound and we get the sensation of hearing.
