Question

Draw a neat labelled diagram of human ear and explain its working.

Answer 1

 

                Fig. Labelled diagram of an ear

When the sound vibrations fall on the funnel shaped outer ear, the vibrations are transmitted through the ear canal to the eardrum which is a rubber membrane and vibrates when sound vibrations fall on it. Then the vibration goes to the inner ear from which it goes to the brain. This is how we hear.
