Loud and Quiet Sounds

Have you ever whispered a secret and then shouted hooray — and felt the difference? Sounds are all around you, keeping you safe, like a car horn warning you or a quiet lullaby helping you sleep. A rocket launching is one of the loudest sounds ever — it can be heard from miles and miles away. When you finish, try tapping a drum softly, then harder, and listen to how the sound changes each time.
