? Library of Wonders   The Wonder of Sound

Did you know you can touch sound?

Have you ever felt a thumping feeling, like gusts of wind, when standing near percussion instruments? Those are vibrations in the air carrying the sound. You can’t see the vibrations, but you can definitely touch them and feel them. If you want to feel a lot of sound, try hitting a large drum as hard as you can. The bigger the surface you hit, the more air you can make vibrate. And the harder you hit the surface, the stronger the vibrations.

But life would be difficult if we could feel every sound. Think about all the sounds around you all the time. If you could feel them all, your body would be constantly trembling. But you don’t have to worry. Sounds spread out in all different directions. And the farther they go, the smaller they get.
