Explore the surprising side of sound with Sound Uncovered, an interactive book featuring auditory illusions, acoustic phenomena, and other things that go bump, beep, boom, and vroom.

From the makers of Color Uncovered—the Exploratorium—this app puts you at the center of the experiment: Hear with your eyes, see with your ears, make and modify recordings, test your hearing, and more.

How do you make a saxophone growl? Are there secret messages in music played backward? Why does the sound of gum chewing drive some people mad? Listen up and find answers to these questions and more as you take an auditory trip to the place where sound gets truly interesting: the space between your ears.

Find more to explore from the Exploratorium online at www.exploratorium.edu. Better yet, visit us in person at our new home at Pier 15 in San Francisco, California.

***Tip for users with sound playback issues: make sure the side switch on your iPad is not set to mute. (This is separate from the volume control.)

Works well!

This is a nice app about the science of sound. It covers many of the more obscure areas such as car manufacture and beat frequencies. Well worth your time!
