How can we hear

How can we hear?

We have 5 sense,out of which sound is one of those.We can hear with the help of our ear.But it is the broader idea,main theory is littlebit complex.In side the ear there is different parts of ear ,internal ear is on of those.In internal ear there is some mechanical system like box.Suppose we hang a paper freely in front of a large box.We can observe that the paper will vivrate with the sound.Because as the box produce sound it vivrating itself,along with that the air in front of the box is also vivrating because it is being vivrate by the box.And the air make the paper vivrate.Just like that external sound vivrating our internal ear.Internal ear makes an electrical impulse as it getting vivrating means getting sound.This impulse goes inside our brain and gives the information and that is translated in our mind language.This is the process of hearing.The power and quality of sound is measured by its frequency of the sound.If it ranges in between 20-20000 then it can make sense of hearing in human.Apart from this range human can't hear.
