When we hear a sound, does any part of our body vibrate? Name the part.
When we ear a sound, our eardrums vibrate:
⇒ When sound enters in the ear, it travels down a canal at the end of which a thin membrane is stretched tightly.
⇒ The thin membrane is called the eardrum.
⇒ Sound vibrations make eardrum vibrate.
⇒ The eardrums send these vibrations to the inner ear. From there, the signal goes to the brain.
⇒ That’s how we hear a sound.
