How Does Noise is All Around You Work?

Noise is all around you because things are always moving and bumping into each other.

Imagine you're in a big room full of bouncy balls. Each ball represents something, like your voice, music, or even the wind outside. When the balls move and hit each other, they make sounds. That's what happens when you hear noise, it’s just all those things moving and bumping around.

Things that vibrate create sound. Think of a drum, when you hit it, the skin moves back and forth really fast, making waves in the air. Those waves are what your ears pick up as sound.

Even things that don’t seem loud can make noise. Your toys, when you shake them or drop them on the floor, vibrate too. That’s why you hear a clatter, it's just the toy bouncing around and making sound waves in the air.

So whether it's your brother laughing, your dog barking, or even the wind outside, noise is just things vibrating and sending out waves that travel to your ears.
