Answer -
The ear transmits several signals to the brain through its different parts who play a specific and important role in reaching the signals to brain.
The outer ear is known as Pinna. It collects the sounds from surroundings. The sound which is collected by pinna passes through the auditory canal. Here, there's a thin membrane called as ear drum. When it reaches to the ear drum, the pressure on the outside of the membrane increases and forces the ear drum inward.
Then the ear drum vibrates. These vibrations are amplified several times by three bones, the hammer, anvil and stirrup which are in the middle ear.
Then the middle ear transmits the amplified pressure variations to the inner ear which turn them to signals by the cochlea.
Now, these signals are sent to brain by the auditory nerve, and then the brain interprets it as sound.
Hope it helps !

Heyaaa!!!
Here's the answer :-
The outer ear (pinna) collects the sound from the surroundings. The collected sound passes through the auditory canal. At the end of the auditory canal, there is a thin membrane called EARDRUM. When a compression of the medium reaches the eardrum, the pressure on the outside of the membrane increases and forces the eardrum inward. Similarly, the eardrum moves outward where a rarefaction reaches it. In this way eardrum vibrates. The vibrations are amplified several times by three bones in middle ear. The middle ear transmits the amplified pressure variations received from the sound wave to the inner ear, the pressure variations are turned into electrical signals by the cochlea. These electrical signals are sent to the brain via the auditory nerve and the brain interprets them as sound.
Hope it helps u!!
