Sound Introduction

Most of us spend our days surrounded by noises of every imaginable origin—the trill of a bird, the thump of a neighbor’s stereo, the blast of a train whistle.

Pleasing or not, all of these sounds carry important information about the world around us.
Our elegantly designed ears and brain capture and transform vibrating waves of air into the sounds we hear.
Try the ear-tingling activities in this section to unlock the secrets of sound, explore hearing and perception, and have fun playing and making sounds in unusual ways. Get started by creating laser-light shows with your voice!
