What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why can you tell how big a room is with your eyes closed?

The Big Idea

You can tell how big a room is with your eyes closed because every room has its own sound! A big room has longer echoes and a lingering sound. A small room sounds tight and dry.

Big Room Sound

Step one: big room sound. In a gym, sound travels far before it hits a wall, then lingers and fades slowly. It sounds roomy and open.

Small Room Sound

Step two: small room sound. In a closet, the walls are close and everything is soft, so the sound stops quickly. It sounds tight and dry.

Trained Brain

Step three: a trained brain. Your brain has learned these clues from a lifetime of listening, even when you do not notice. Soft furniture makes a room sound quieter.

A Closer Look

Let's take a closer look! A big room has long, lingering echoes. A small room sounds tight and dry. Soft furniture soaks up sound. Your brain puts the clues together. A room's sound is like its face.
