Question

explain briefly how ear work,and therefore how we hear?

Answer 1

The outer ear collects sound wave which are conducted through auditory canal
these waves fall into ear drum and set it into vibration
The middle ear which is the size of a small marble and houses ossicles(three bones hammer,strrup,anvil) amplifies these oscillation about 60 times
the inner ear which contains cochlea filled with fluid convert these pressure vibration into electric signal
these electric signal are conveyed to brain through auditory nerve for interpretation

Answer 2

The human ear is an organ whose primary function is to hear a sound and to detect and analyze noise by transduction (sound waves are converted into the electrical impulses). In some mammals, it is also used for the sense of balance. Now the question is how compression in air results in sound in our brain.

The compression in the air has to be converted into electrical signals for our brain to detect. Let’s study the structure of the ear and how the whole process of conversion of air compression into electrical signals takes place.
