Question

Sound is produced by vibration. To detect sound, some part of our ear should also vibrate when sound strikes it. Which part of the ear is this and how does it help us in hearing the sound?

Answer 1

The vibrating part of our ear is called the eardrum. When a sound with a certain frequency strikes the eardrum present inside our ear, it starts vibrating with the same frequency as the sound wave. The eardrum sends these vibrations to the three bones present in the middle ear. These bones amplify the vibrations and send it to the inner ear. The inner ear changes this information into signals and sends it to our mind. That's how we are able to listen to any sound.
