Why is it said that the ear plays a wonderful role in receiving sounds?

            The human ear is a wonderful organ that performs some of the most important functions in the body. It detects and analyzes sounds, and also maintains the sense of balance.

            Structurally, the external ear is created in a peculiar way. It has many twists and folds that help in enhancing certain sounds up to 100 times.

            Designed in a way as to make the skin maintain its funnel shape, a healthy ear enables the capturing of even the tiniest vibration.

            In addition, the ear can help determine sound direction. It can also decide the range of sounds we hear. However, as we grow old, we become less sensitive to sounds, and may not be able to hear high pitched sounds like the squeaking of a bat. But this could be picked up by a child. It has been found that a normal human can detect frequencies between 20 Hz and 20 kHz.
